95-01 5spd VLSD rebuild (open diff part numbers too)

I’ve rebuilt 8+ or so 5spd open/VLSDs. Converted plenty of 6spds to HLSD/spec-V 6spd swaps. So it’s not a big deal for me to undertake something like this in a week.

I usually work thru and don’t stop to take pictures, so here’s some pics I was able to snap in between working/breaks. This is not a guide by any means, just familiarizes you with what is involved. This is not a job for someone who doesn’t have intermediate/advanced wrenching skills – so you’ve been warned..

it took me a week to disassemble my first 5spd back in 2005, now ~3 hours. If you are not familiar with how a manual transmission works internally, or are not confident in your abilities or can’t deal with issues when issues arise – leave this job for someone who knows it well.

I did not show the disassembly of shift forks/pins/how to set the check ball system/reverse gear/proper way to re-shim new bearings and other complex parts of rebuild, so once again this is NOT a how-to guide in any form or shape – I’m just posting pics of my progress.


All ordered from Nissan = NACHI/NSK/NTN high quality Japanese bearings.
I’ve seen cheap kits with unknown bearing brands (made in china) and would not recommend using them due to the questionable quality of bearings

  • Input shaft bearing 1 – 32203-03E13
  • Input shaft bearing 2 – 32203-03E00
  • Main shaft bearing 1 – 32273-79E00
  • Main shaft bearing 2 – 32223-79E62
  • Pass side diff bearing (open diff – 2X) – 38440-96E00
  • VLSD driver side diff bearing (EXPENSIVE) – 38440-79E01
  • Input shaft seal – 32113-03E00
  • Shifter yoke seal – 32858-03E00
  • Pass side axle seal – 38342-81X01
  • VLSD driver axle seal – 38342-51E00
  • Open diff driver axle seal – 38342-81X00

How do you know if you have open diff or VLSD (the dumb way – look at the transmission)

  • if axle seal is small = open diff (left)
  • if axle seal is large = VLSD (right)

Now that you know what transmission you have you can get the proper seals/bearings.. not gonna be cheap (VLSD bearings are ~$450)

Having suspected a rear main seal leak for some time and oil covering tranny case (although bad diff. bearings also to blame) and high oil consumption. I dropped the tranny to do a tranny swap and found that the rear main seal was definitely leaking. There was no clutch slippage and the clutch disc did not have evidence of contamination–I think the flywheel shielded it some.

Flywheel removed (note oily residue all over):

Step one: Drain engine oil. Clean area (I used brake cleaner) and remove old seal–it is more of a bracket with integrated inner rubber seal. This includes any old stuck-on gasket sealant attached to the metal surfaces. It should look like this after:

Step two: With new OEM rear main bearing seal in hand (THANKS, JRNISSAN!), coat the appropriate edges with permatex high-temp gasket sealant — the edges will have a channel to hold in the sealant. Coat the inner rubber seal with a light coat of motor oil.

Step three: Very carefully insert seal. Make sure you do not deform (ie. force it) the rubber inner seal or you will tear it (the damned seal ain’t cheap!) or the metal inner retaining spring will pop out. You want to gently nudge it over the crank so the seal sits flush. Make sure you allow sufficient time for the Permatex to cure.

The end result should look like this:

Preface: The whole idea behind a manual transmission is there is no electronics needed to run it ? basically, our slogan was, if the car starts and revs, the conversion will work. The converted car did not have ABS, but our donor car did ? ABS IS A PAIN because it sits right where you will run the hydraulic lines (In a factory 5 speed w/ ABS the lines run under the ABS brain)! Factor in more time if you have Antilock Brakes System. The converted car was a 1995 Nissan Maxima SE, and the donor car was a ’96 Nissan Maxima SE w/ ABS ? I don’t know about other year Maxima’s, but I would assume all 4th gens are somewhat the same when it comes to this conversion (please email me if you know otherwise). I am not liable if you mess up your car, mine worked PERFECT, but don’t blame me if you screw it up!

Before you do the conversion: Check to make sure that you can physically put the transmission in every gear before putting it in the car. Our first transmission’s shifting rod (part in the tranny) was slightly bent and we didn’t realize that we had to junk that tranny until AFTER we had everything finished and realized the car wouldn’t go into gear.

1. Bypass the P-N start switch
2. Install pedals and clutch hydraulic system
3. Remove drive shafts
4. Remove tranny + torque converter
5. Install clutch setup.
6. Install tranny
7. Replace old shifter console w/ new and run shifting rods to tranny
8. Reinstall drive shafts

Bypass the P-N start switch

1.1 TAKE OFF BATTERY CLAMPS (neg and pos) to make sure you don’t mess something up electrically.

1.2 Remove the entire air box assembly and lines so you can see onto the top of your tranny.

1.3 Disconnect the harness that goes into the front of the tranny that only has 2 wires. (Note: the front of the tranny refers to the part that is closest to the front of the car)

1.4 Get your wire and cut a 6 inch strip

1.5 Use the wire taps to connect the 6 inch piece of wire to both of those wires (This will in effect connect these wires)
Add-on to the instructions:

In step 1.5, it says to connect two wires on the tranny harness. You instead, need to run a wire from both of the tranny wires, to the clutch pedal switch (small switch that is engaged when you push the clutch all the way down). This will let your car know when it is “Neutral (since it thinks it is an automatic)”.. your reason for doing this, is so that 1. You cant start the car without the clutch (safety)… and #2, SO CRUISE CONTROL WILL WORK.

1.6 Don’t reconnect the plug.

1.7 Connect the battery.

1.8 Put your parking brake on

1.9 Try to crank your car (Don’t start it, just see if it cranks)
If it does not, re-tap the wires or connect them in some way. And try to start again.
If it still does not start you can’t follow instructions and are not capable of doing this yourself since it is the easiest part.

2. Install pedals and clutch hydraulic system

Tools needed:

  • Drill
  • Phillips head screw driver
  • Metric socket set w/ extensions
  • Good drill bit set
  • Pencil
  • Tree bit (stone bit shaped like a tree, they sell it at Home Depot)
  • Cylinder bit (stone bit shaped like a cylinder, they sell it at Home Depot)

2.1 TAKE OFF BATTERY CLAMPS (neg and pos) you don’t want to burn anything up or blow your airbags.

2.2 Remove lower drivers dash cover (2 Phillips head screws at the bottom)
Pull the cover off w/ caution not to damage the clips at the top.

2.3 Remove the Metal bracket just under the steering wheel (2 12mm bolts)

2.4 Remove the plastic shield from around the steering wheel column (6 Phillips head screws)

2.5 Pull the cover apart and off.

2.6 Remove the plastic housing around the Speedo. (2 Phillips. screws) pull it being careful not to damage the clips at the bottom.

2.7 Unplug the items that are mounted on it.

2.8 Remove 4 screws that hold in the Speedo.

2.9 Pull the Speedo out toward the passenger side. (you can leave it connected)

2.10 Remove the 2 12mm bolts that are now visible where the Speedo sat on the lower left side. That holds a bracket in.

2.11 Reinstall the Speedo. (Don’t worry about those screws needing to go back in)

2.12 Reinstall the plastic housing

2.13 Remove the clip and pin that hold the brake pedal cable on.

2.14 Remove the 4 nuts that hold the break pedal on.

2.15 Remove the 12mm bolt that holds the top of the break pedal on.

You will see where it goes because you will have manual one as a reference

Hopefully you have bought a matching bolt from Nissan, if not take it to the dealer and get one. You can’t install the clutch pedal w/out it.

2.16 Remove the 4 bolts that hold the steering wheel up.

2.17 Lower the steering wheel and let it rest on the seat.

2.18 Remove the metal bracket that the lowest left nut went on.

? Remember you took 2 bolts out of it before in the Speedo area.

2.19 Throw that bracket away. (It is useless.)

2.20 Remove the brake pedal.

2.21 Install the new pedal. (Put the 4 nuts on and the one bolt)

2.22 Put the locking pin in and the clip.

2.23 Bolt your wheel back up. (The three remaining bolts will be good enough.)

2.24 Look up where it seems the clutch should mount.

2.25 If you see a hole in the padding good. If not, you can see it outlined. (Pull it out)

2.26 Now you should be faced w/ a perfect padding hole but no hole through the firewall.

2.27 Make a trace of the master cylinder (I used cardboard)

It will have a big hole and 2 little ones for the bolts

2.28 Cut out your trace and slide it over the master cylinder to make sure it is accurate.

2.29 Mark the top of your trace (that canister on the master cylinder is up)

2.30 Fit it into that area that is punched out under the dash and draw an outline (pencil works great)

2.31 Open the hood.

2.32 Look into the upper driver side area against the firewall.

You will see the cruise unit.
It is the only electronic item in that area.

2.33 Remove it.
There will be one bolt on it and 2 nuts that you access in the wheel well.

2.34 Drill your 2 small holes for the master cylinder from your trace. (From the inside of the car was the easiest.)

2.35 Test the clutch pedal (by putting it through the holes you drilled)

The clutch pedal should be upright and level.
It should fit in there w/out force.
If it does not fit adjust the holes so it does.

2.36 Drill a good size hole in the big part of the trace (Where the master cylinder goes.)

2.37 Use your tree stone bit to make it bigger and work to carve out the hole to the traced size.

2.38 Use your cylinder stone bit to make it bigger and work to carve out the hole to the traced size.

2.39 Test the master cylinder in the hole.

If it does not fit correct the hole

Note: On a factory car w/ 5speed there is a spacer that is ? of an inch thick that is on the inside of the firewall. The 2 bolts that are on the clutch pedal that travel through the firewall go through this spacer, and somehow you will need to recreate it (VERY IMPORTANT!! that you get it just the right size, maybe buy the spacer from Nissan).

2.40 You can recreate it by getting big nuts that fit over these screws and using them as a spacer (or better yet, buy one from Nissan).

2.41 Install the clutch pedal and master cylinder.

2.42 Install the bolt you acquired to match the brake pedal bolt. (The car has this place built in just look for the place)

2.43 Install the locking pin to join the master cylinder and the clutch pedal.

2.44 Put the pin in it.

2.45 Reinstall every panel you removed except the one you tossed.

2.46 Pat yourself on the back.

3. Remove Drive shafts

Tools Needed:

  • Phillips head screw driver
  • Flat head screw driver
  • Metric socket set. (7mm-19mm)
  • Metric wrench set (7mm-19mm)
  • A good breaker bar
  • 1.5″ socket that will attach to your breaker bar.
  • Needle nose pliers
  • 1 jack
  • 2 jack stands
  • Tie rod removal tool (You want the one that screws) (Buy at AutoZone)

3.1 Get on totally nasty “throw away” clothes because you are not going to even want to see them ever again!

3.2 Loosen lug nuts.

3.3 Jack the car up very high, to where the tires are about 9-12in above the ground. Place jack stands under it!!!

3.4 Remove your wheels.

Apply 3.5 – 3.14 parts to both wheels.

3.5 Remove the cotter pin from the center of the rotor area (Wheel Hub)

3.6 Remove the cotter pin from the bolt that connects the Knuckle and the Tie rod.

3.7 Insert the screw driver into the rotor (in those little holes around the diameter)

3.8 Remove that Huge Nut in the center of the rotor. (1.5 inch socket and the breaker bar will be necessary)

3.9 Get the washer off and keep all of these parts clean.

3.10 Remove the nut that holds the tie rod on.

3.11 Use your tie rod remover to loosen it on the knuckle. Then pull it apart.

3.12 Remove the 2 bolts that join the suspension to the Knuckle area.

3.13 Fold the knuckle (brake assembly) area out of the way while LIGHTLY banging on the end of the big threaded shaft you removed the large nut from

Don’t screw up the treads. You can protect them by putting the nut back on and making it even w/ the end.

3.14 You should now have the driveshaft hanging free on the outsides of the car.

3.15 On the driver’s side, push the driveshaft in a little bit (It compresses), and yank it out ? you might have to do it a few times before it comes free. (It will POP out)

3.16 Remove that driveshaft and be very careful not to break the rubber boots.

3.17 On the passenger side, you must go under the car and find the support that the driveshaft goes through before it gets to the tranny. It’s a pain to get at, but there are 3 bolts in a triangle around the outside of the support holding the driveshaft in.

3.18 Remove the three 12mm bolts, and then push in the shaft and pull it out. Be very careful not the break the rubber boots and gently set the two drive shafts aside.

3.19 Pat Yourself on the back you have successfully removed your drive shafts.
Note: Your Shocks/Springs are only 8 min and 3 bolts away from replacement if you want to do it at this time.

4. Remove tranny + torque converter

Tools Needed:

  • Everything from drive shaft removal.
  • 1 hydraulic Jack
  • 1 Nissan Factory Jack
  • 2 bricks (You might need them, depends how high your car is)
  • One extra person

4.1 You now must remove your whole air intake system from the top of the engine. Everything including the rubber 3″ flexible hose. (After your MAF and all that) and unscrew the little clamp. Gently pull it away, and take out all the other bolts (this will be a little different if you have pop vs. cai vs. stock) so you can figure it out. Get all those hoses off and out of the way, so you can see easily down to the tranny.

4.2 Remove all plugs that go into the tranny.

4.3 Remove the dipstick for the auto tranny , it has one bolt at its base.

4.4 Remove the rubber lines that go into the tranny, you can cut them because you won’t use them again.

4.5 Remove the plug that connects to the starter

4.6 Remove the fat wire (pos) that connects to the start itself.

4.7 Remove the starter. (2 17mm bolts)

4.8 Pull the starter out.

4.9 Remove the plastic panels from the driver side wheel well so you can see the side of the tranny.

4.10 Remove the linkage line that goes to the front of the tranny (Fat cable that bolts next on at the front left corner of the tranny)

4.11 Put your hydraulic jack under the tranny.
Just on to the tranny, not so much pressure you are jacking the engine up.

4.12 Remove all the bolts that bolt the tranny on (there are 17mm on top and 14mm on the bottom) except for one 17mm on the front. Just loosen it a little.
These bolts will be hard to break and you will need a breaker bar to loosen them.

4.13 Put your Factory Nissan jack under the support beam (Runs under the Engine/Tranny) toward the front, up close to those 2 bolts but leave enough room so you can loosen and remove them.
This is where you might need the brick to get up to the beam.

4.14 Look down from the top on to your tranny.

4.15 You will see a motor mount sort of next to your battery w/ 4 bolts going into the tranny

4.16 Remove these bolts.

4.17 Very slowly, lower the transmission 1/2″(Hydraulic Jack) and then the engine 1/2″(Nissan Jack) until they are sitting very low where the transmission is clear of anything in its way coming off the engine.

4.18 Remove the last 17mm bolt that holds the transmission onto the engine.

4.19 Have your extra person ready.
They will work the jack as you do the wiggling, wedging and clearance checking

4.20 Look for a place between the tranny and the engine that you can stick a screwdriver

4.21 Crack the seal w/ a screwdriver.

4.22 Now pull the tranny away from the engine wiggling it off the engine gently (don’t let that rod be bending around or rest the weight on that center shaft!)

4.23 Now, using the jack slowly lower the transmission to the point where you can roll it out the driver side wheel well.

4.24 You are now looking at the torque converter mounted on the engine.

4.25 Go get some food and Pat yourself on the back.

4.26 Look at the bottom of the engine (Sort of from the passenger side) and you will see a black cover w/ 2 small bolts.

4.27 Remove the bolts and the cover.

4.28 While looking through this hole use your screwdriver to rotate the flywheel around on the teeth of the flywheel until you see a bolt.

4.29 Use the screwdriver as a wedge to prevent the flywheel from turning and remove the bolt.

4.30 Repeat for all four bolts.

4.31 Slide the torque converter off.

4.32 Now look at the flywheel and you will see 8 bolts in the center bolting it to the crankshaft.

4.33 Use your screwdriver wedge to break loose all the bolts.

4.34 Remove the bolts and your flywheel.

4.35 Remove the bolt that holds the tranny motor mount and remove it.
The manual one is different.

4.36 Good job, you just ate so I would continue installing your new clutch setup.

5. Install clutch

Tools Needed:

  • Torque wrench
  • Hayes Manual
  • Metric Socket Set
  • Screwdriver
  • Clutch aligning tool

5.1 Take your flywheel, line it up on the engine, and attach it in place of the old one.

5.2 Torque it to the specs in the Hayes Manual, using your screwdriver wedge.

5.3 Make sure the flywheel is VERY clean, no grease on it? if there is use 409 to clean it, and sand it with 180grit or more sandpaper. VERY IMPORTANT that it is clean

5.4 Put in your clutch aligning/centering tool in the engine hole.

5.5 Slide your clutch on over the tool.

5.6 Slide on the centering piece of the tool and get the clutch just right.

5.7 Put on the new pressure plate you have, make sure the clutch is centered and pressure plate lines up right, and bolt it all down, making sure you do it with a torque wrench as it is VERY important in there.

5.8 Remove the tool.

5.9 Now go get some sleep seeing you probably did most of this yourself and it took all day.

6. Install the Tranny

Tools Needed:

  • Torque wrench
  • Hayes Manual
  • Metric Socket Set
  • Screwdriver
  • 1 hydraulic Jack
  • 1 Nissan Factory Jack
  • One extra person

6.1 Put the manual motor mount back up into the car w/ the “M” symbol facing the engine.

6.2 Put the 5spd tranny on the jack and roll it in through the wheel well the same as you took the other out.

6.3 Slowly lift it up w/ the jack to where it seems to be aligned.

6.4 Make sure that it is lined up just perfectly level w/ the engine when doing this, because once you put it on the engine, it is virtually impossible to rotate it and it HAS to line up PERFECT for the bolts to go in (Can be very frustrating)

6.5 Here is the hardest part, wiggle the transmission over toward the engine until it is flush.
Be sure to have the shaft going through the middle of the of the pressure plate.
If it won’t continue to travel rotate the flywheel (w/ your screw driver) just a little and try it again.

The shaft and clutch have little teeth that need to align.

6.6 Quick put a bolt on (The front 17mm is the easiest)

6.7 Work all the way around the tranny putting the bolts on. You might need the jack to make small alignment adjustments to get some bolts on.

Make sure and leave the bolt (or both of them if you are going to try) for the shifter stabilizer out so you don’t do it twice

6.8 Lift the tranny 1/2″ and the engine 1/2″ and so on and so forth till its back up.
Have your helper make sure the motor mount does not bind and lines up w/ the holes on the tranny.

6.9 Put the bolts in the support beam and the motor mount onto the top of the tranny.

6.10 Put in the starter using the two bolts.

6.11 Torque all the bolts to spec.

6.12 Connect all the wires back to the starter.

6.13 Plug in whichever harnesses still plug together.

6.14 Put the plastic panels back on in the left wheel well.

6.15 Fill the tranny w/ fluid using the holes where the drive shafts go in.
It is full when fluid starts coming out of the hole.

6.16 You are almost there you have done everything hard.

7. Replace old shifter console w/ new and run shifting rods to tranny

Tools Needed:

  • Phillips head screw driver
  • Flat head screw driver
  • Metric socket set. (7mm-19mm)
  • Metric wrench set (7mm-19mm)
  • A good breaker bar
  • 1.5″ socket that will attach to your breaker bar.
  • Needle nose pliers

7.1 Now comes some fun. From inside the car, pry up the console piece that sits around your automatic shifter w/ the screwdriver.

7.2 Pull it off and out of the way.

7.3 Take the screw out that holds the shifter handle on.

7.4 Pull it up and down while trying to pull the button off. It will come off the shaft.

7.5 Remove the cover w/ the shift indicators on it (has some Phillips head screws)

7.6 Look down into the hole and you will see 2 cables coming in.

7.7 The small one on the left (Toward passenger side) is the key release linkage.

7.8 Remove the clip that holds it on and pull it out a little (in only moves 1/8 of an inch) wrap tape around it so it can’t move. I does not want to move so don’t worry.

7.9 Remove the larger cable and bend it out of the way.

7.10 You can remove the cable or cut or bend it, it was what changed the gears in the automatic but is now useless.

7.11 Remove the 2 nuts on the top that holds the Aluminum frame onto the painted area of the car.

7.12 There will be two nuts holding the assembly up from the underneath ?

7.13 Go under the car, and pull the rubber things that hold your exhaust up? there are 3.

7.14 Unbolt the heat shield on the ends (not in the middle) so you can get under it.

7.15 Take out the two bolts from the bottom that hold the shifter piece in your car, and remove it from the top.

7.16 Run the two shifting rods above the heat shield.

7.17 Put the shifter piece in the car from the top, but don’t bolt it.

7.18 Go back underneath the car and put the spring in (It runs between the 2 rods)

7.19 Bolt in the shifter.

7.20 Attach the support rod (W/ 2 bolts if you can get them) to the Tranny/Engine.
There is only one place it will bolt so it won’t be too hard to find.

7.21 Attach the shifter control rod to the transmission

7.22 Put trim piece back inside of car and screw on the shift knob.


8. Reinstall drive shafts

Tools Needed:

  • Phillips head screw driver
  • Flat head screw driver
  • Metric socket set. (7mm-19mm)
  • Metric wrench set (7mm-19mm)
  • A good breaker bar
  • 1.5″ socket that will attach to your breaker bar.
  • Needle nose pliers
  • 1 jack

8.1 Reinstall the MANUAL drive shafts. (They are different then the automatic shafts)

8.2 Put the left one in first.

8.3 Put the shaft in as good as possible. (Be careful not to damage the boots) Then sort of extend the joints and slam them together. The idea is to make it into a self-sufficient hammer. Until it clicks into place. It will!!

8.4 Reinstall the Knuckle (Brake assembly).

8.5 Remember your big washer and be sure to get that big bolt tight.

8.6 Put passenger drive shafts back in, don’t forget the triangle that locks the passenger side one in.

8.7 Put center driveshaft bolt back on, cotter pin in, control arm bolt and cotter pin, and two bolts that mount the wheel to the suspension.

8.8 Wheels back on, drop the car.

8.9 Turn the car on; let it idle for about 30 ? 60sec to make sure oil gets through the engine and tranny.
HAVE FUN!!!!!! Remember you have to BABY that clutch all the time for the first 500+ city miles

REVERSE LIGHTS WIRING: (Thanks Stephen Max for write up)

The back-up lights turn on when a circuit is completed when the transmission is in reverse. This is true for both automatic and manual transmissions. All you have to do is find the correct wires in the automatic harness that go to the gear selector mechanism of the automatic, and splice them into the wires that go to the neutral/reverse position indicator on the manual transmission.

1. Look for a large, gray wiring harness connector that is unused. This used to carry a bundle of wires to the gear selector mechanism on the front of your automatic transmission. This harness connector should just be dangling somewhere around the top of your manual transmission about where the slave cylinder is. There are eight wires that go into this connector. The wires you need to find are the solid green wire and the green/white wire. Splice two wires into these two. To test to make sure you got the correct two wires, turn on your ignition and touch the ends of the two splices together. Your back-up lights should come on regardless of what gear you are in.

2. Find the harness that comes from the neutral/reverse position indicator switch on your manual transmission. The switch is the one that is down at the bottom of the transmission and there are four wires in that harness. The wires you are looking for are the blue wire and the blue/red wire. To make sure you got the right two, put the transmission into reverse and get a multimeter and check the resistance across the two pins in the connector that correspond to the blue and the blue/red wires. The resistance should be near zero.

3. Now just take the two splices from the auto harness and splice them into the blue and blue/red wires in the manual harness. It doesn’t matter which splice goes to which wire.

Now, for the questions everyone wants me to answer..

1. Q: Is it really worth it? A: It is a whole lot of work, I will say that right now. When you are doing it, it gets frustrating and seems almost not worth it. When you take your first ride in it converted to 5spd, it makes everything worth it 10x!!! And then to realize you get to drive it every day as a 5spd from then on. Without a doubt I would do it again in a heartbeat.

2. Q: Does it really work and is it still running? A: Yes, I have been running on it for over a year now, with no problems. The thing runs AWESOME, no trouble from it so far (knock on wood) and I have really DRIVEN the car a TON(

3. Q: How much did it cost? A: This is the hardest question to answer… can’t really give you a dollar amount. People are paying anywhere from 800-1500$ for all the parts (check a bunch of junkyards, even if they have to ship the stuff…). Then labor, you can attempt it yourself, its not super difficult but it isn’t exactly like putting a strut bar on.. I would advise having someone who is very experienced do it with you, or pay a shop to do the labor (prices can vary a TON!!.. 500-1500+$)

So I’ve been asked to do a write-up on how to make the Z32 MAF setup work with the JWT ECU + 370cc Injectors while Supercharged on the charged side.


With the Z32 MAF on the charged side and stock Stillen piping the car idles horribly, bucks hard when cold, and is generally not drivable.


The Stock Stillen piping doesn’t work well with this setup. After spending a year trying to figure out if it was compressor surge, vacuum leak, etc, etc it turned out the reason (And solution) is quite simple.

I needed 3″ Piping.

The reason is not compressor surge or any performance boost with 3″ piping. The reason is simply that with the flange on the stock Stillen piping facing the way it faces, it causes the MAF harness to face up or down.

It must face towards the battery – like this:

As soon as I had the 3″ piping in originally (With the harness facing up) – it still idled and ran horribly especially when cold.

Turned the MAF 90 degrees – and problem solved.

Z32 MAF Part Number: 22680-30P00
Tomei Z32 Airflow Meter Harness Part Number: 194002

The Z32 Mass Air Flow (MAF) sensor is great for turbo or supercharged setups. If you are not boosted then you do not need these. If you are boosted, the Z32 MAF allows you to measure more airflow into the engine than what the stock A32 MAF can. The Z32 MAF is calibrated for higher airflow and you can stay with an airflow referenced fuel metering system. The A32 MAF maxes out at an airflow equivalent to about 300HP and the Z32 MAF can meter about 500HP worth of air.

The J30 and the Z32 MAF both have the same sensor, just different harness connectors. The Z32 connector has two extra unused pins. Sometimes you can save money if the junkyard dealer doesn’t realize that the J30 MAF is the same as the Z32.

To simplify the installation, you can grab a Tomei Harness. The part number is 194002.

Brief Details: What can the device be used for:
In the VTEC AFC II, the VTEC changeover point of a vehicle with a VTEC engine (in our case 00VI/MEVI) can be adjusted at an optional engine RPM. This fuel adjustment controller can increase and decrease fuel in a wide range of +50% to -50% by 1-point increments for the specified engine rpm. RPM points can be set in 100 rpm increments and make fuel correction according to the throttle position.

The second-generation SAFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The SAFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. The SAFC is capable of monitoring and replaying the following data channels in Numerical, Analog Meter and Graph displays: Intake Manifold Vacuum/Boost Pressure, Air Flow Capacity, Intake Manifold Pressure, Karmann Frequency, Engine RPM, Throttle Position, and Air Flow Correction %.

Tools Required: Necessary components used to install the VAFC to an A32:

  • Wire cutter
  • Wire Crimper
  • 10(or 12mm) socket and ratchet
  • Soldering iron with 16-22ag solder
  • Electrical tape
  • Snap connectors

Warning: I am not responsible if you fry your electrical system or damage your engine. Use caution when working with electricity and please disconnect the battery before proceeding!

Installation: Installing into your 1995-99 Maxima

You will need to access the passenger side of the ECU so from the passenger side of the car remove the kick plate to reveal the sealed harness to the ECU. Undo the 10mm socket from the center of the harness plug and separate the harness from the ECU. Pull off the clear plastic shielding which encases the wiring and we will begin the taping of wires for your new S/V-AFC II.

From here you will need to match up accordingly the wiring from the V-AFC II Harness to the wire location (NOT COLORS) on the ECU harness. Please note that you will not be using the Light Blue, Purple, or Orange wires from the V-AFC harness, tuck them away. Take note of subscript on ECU harness image for the location of Blue(O2 sensor hookup wire). Solder all wires securely and cover with electrical tape. Below are an V-AFC wiring diagram, an S-AFCII wiring diagram, and also the pin-outs on an A32 ECU harness, please use them properly to match up the wires. Failure to do so will result in damaged electronics or engine.


Initial V-AFC II Setup: Before you can start the engine you will need to setup the V-AFC.

Now that you have securely solder all the necessary wires to the ECU you may now begin the setup to make sure you do not damage the engine on startup. Turn ignition to the ON position but DO NOT start the engine and your newly installed V-AFC will come alive. Navigate through the menu’s, be sure to take it slow as not to incorrectly configure a vital setting. Move to the ETC menu; hit right on your joystick, scroll down and continue into Initialize, and toggle over to Yes. Accept the choice, after doing so wait 5 seconds and turn the ignition to the OFF position. Doing so will clear any unwanted information stored in the device if you happened to purchase the device used.

Return the ignition back to the ON position but DO NOT start the engine. Your V-AFC will activate again for more information to be stored. Navigate into the ETC menu again, and proceed to enter the following:

Sensor NO: 4 IN, 4 OUT (Assuming you are running a A32 MAF) –Otherwise*1*
Car Select: 6 Cyl, Arrow UP and RIGHT, V/T 1
Sensor CHK: Ensure sensors are giving readings

Further tuning settings will need to be fine tuned while on a dynamometer. Once all settings have been checked over, turn the ignition to OFF wait 5 seconds and return the ignition to ON one last time. While your V-AFC is booting let the throttle rest at 0% for 10 seconds, and depress the throttle to 100% for 10 seconds and release. You have now completed the learning sequence for throttle positions and you can proceed to start the car.

If you are tired of your OEM plastic radiator cracking or just simply looking for an upgrade, the 4thgen radiator is a very good option. It fits perfectly on the 2000-2003 5thgen and only costs around $100 bucks. The quality is great and equal to those of other known brands like Mishimoto and Megan (in my opinion). I have been running this radiator on my Supercharged 5thgen with no issues for years now. This post contains all the details you need to know.

Important Note for Automatic Transmission Owners

You will notice that most aluminum radiators say “Manual Transmission Only”. This is because the Automatics have a cooling hose that flows between the radiator to the transmission. You can easily purchase a transmission external oil cooler and you will be all set. One of the most commonly used brands is Hayden and you can find it any local parts store. Below are some reference photos. Here’s a link to a write-up which can be helpful: https://www.my4dsc.com/how-to-install-transmission-cooler/
