If you are considering upgrading your Nissan Maxima to a newer engine model, we recommend going with the 2016+ Gen3 VQ35DE Nissan. They have also come down in price and present a great option for a low mileage and newer engine. We’ve seen them as low as $850-$900 depending on mileage. There is also nothing wrong with considering a Gen2 VQ35DE (2009-2015) engine especially when you can get them at a much lower costs than Gen3. Ultimately, you make the decision on what is best, cost effective and convenient for you.

Overall, the 2016+ Gen3 engine has many new improvements over the previous 2009-2015 7thgen Generation Model Maxima. According to Nissan, the 2016+ engine has upgraded 61% over the previous engine. It also applies lessons learned and new technology from the legendary Nissan GT-R, such as sodium-filled valves.

Why it’s called Gen3 VQ35DE?

We’ve dubbed it the “Gen3 VQ35DE” to differentiate between the different years of the VQ35DE engine. When you hear Gen3, you know it’s an 8thgen 2016+ motor vs 7thgen.

  • 2002-2008 – 1st Generation VQ35DE (5thgen/6thgen)
  • 2009-2015 – 2nd Generation VQ35DE (7thgen)
  • 2016+ – 3rd Generation VQ35DE (8thgen)

Engine Specs:

Key Improvements Include:

  • Reduced Friction and Weights
  • New Upper Intake Manifold
  • Intake Runners Are Shorter and Wider for Improved Flow
  • Exhaust Valves Are Sodium-filled — Just like on the R35 Nissan GTR, and Other High-end Sports Cars
  • All New Part Numbers in the Cylinder Heads and Valvetrain, All-new and Reconfigured to Encourage a High Degree of Airflow
  • Timing Chains Driving the Valvetrain Are Redesigned with a Special Low-friction Design
  • Piston Skirts Are Anodized
  • Piston Rings Have a Diamond-like Coating Treatment, All to Reduce Friction
  • Oil Pump is Redesigned for Improved Flow
  • Oil Pan is Revised with Additional Ribbing to Reduce Noise Transmission
  • New High-flow Monolith Catalytic Converters That Reduce Exhaust Back Pressure

Swap Information:

The newer 2016+ 8thgen Motor has more solenoids that previous 7thgen Motor. If you are putting this in a older maxima, you need to hook up the solenoids noted in the photo.

If you are DIY person and love working on your Nissan Maxima, then this tool is a MUST HAVE! When you go to the Nissan dealer, the person working on your car typically uses a tool called a Nissan Consult. The Nissan Consult that the dealer uses costs thousand of dollars and is only available to dealers. By using the Nissan DataScan software, a laptop and a generic VAG COM OBDII adapter you can achieve just about the same level of on-board diagnosis that $5,000 Nissan Consult provides. This software allows you to:

  • Check CEL codes
  • Check/Reset ABS and SRS-Airbag Faults
  • Check/Reset TCM Codes
  • Adjust timing
  • Perform Idle Air Relearn
  • Reset ECU learned settings
  • Data-log
  • Program keys
  • Check Emissions Readiness Monitors
  • Active Test temporary modify some of the engine parameters for testing purposes
  • And Much much more….

The software itself costs $55.00 and generic cable costs around $7.00-$8.00.

Below are all the functions it provides:

ECU Part Number

This is the main window of the NDSII software which shows the ECM Nissan Identification part number. Basic and Advance Functions can be selected by clicking on the buttons, using the shortcut keys (F1 – F11) or using the Menu bar. Most functions except Data Replay and Log Analyser are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates communication between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

Data Display Settings

This window is used to assign parameters to be displayed by the Data Display function. Only parameters that are supported by the currently connected ECU are available for selection. Gauges are counted from left to right, top to bottom. Multiple gauges can monitor the same parameter.

Data Logging ECM

Selected parameters can be logged to a file. This function can also be accessed from the Data Display window. The data log file can be analysed using the Data Replay or Log Analyser functions.

Self Diagnostics ECM

Self Diagnostics function allows users to read and reset engine ECU error codes.

Idle Adjustment

Idle Adjustment function allows users to adjust the base idle RPM. The setting is saved to the ECU and it does not reset with engine restart.

Timing Adjustment

Timing Adjustment function allows users to adjust the base ignition timing. The setting is saved to the ECU and it does not reset with engine restart.

Active Test ECM

Active Test allows users to temporary modify some of the engine parameters for testing purposes. They return to their original values when a function is stopped, PC disconnected or engine restarted.

Note: It is possible to damage the engine if the A/F Base % functions is used to excessively modify fuel delivery. Likewise the engine may overheat if the Engine Temperature is set to low for a long period of time. Do not use those functions if you are not sure how they will effect your engine.

Work Support

Work Support functions allow users to perform some of the advance service procedures. Those procedures may need to be performed after replacement parts are installed.

Clear Self Learn – clears the A/F Base SL map learned by the ECU.

Idle Air Volume Learn – is an operation to learn the fully closed position of the throttle valve.

Program Immobiliser Key – allows to register the Nissan transponder keys with the Immobiliser Note: The immobiliser security PIN CODE needs to be known. Initially all registered keys will be erased and all keys will need to be reregistered.

Cylinder Power Test

Cylinder Power Test function can be used to identify cylinder that is under performing. This function allows shutting down individual cylinders. If all of the cylinders are producing the same amount of power the engine RPMs will drop exactly the same amount on each cylinder that is cancelled.

Log Analyser is used to review log files previously generated by with Data Logging function. Graphs are drawn by selecting boxes next to parameter value. Graph colours match the parameter value colours.

Speed Test

Speed Test is a unique function for measuring car’s acceleration performance. Predefined or user specific tests can be used. Due to the low resolution of Nissan speed sensors, measurements should only be used as a guide and not a true reflection of car’s performance.

Note: This function should not be used while driving on public roads.

Address Watch

Address Watch function is used for monitor specific ECU memory addresses. By monitoring a memory address extra information can be retrieved that is not normally available using Consult II protocol. A knock sensor reading can be obtain using this method if knock sensor memory address is known.

Wideband O2 sensor

Nissan DataScan II also supports wideband Air/Fuel ratio meters from Innovate Motorsports. A second serial port is used to connect to the controller and collect data.

The data from the wideband meter can be displayed or logged in conjunction with other engine parameters using the Data Logging function.

ECU Part Number BCM

The BCM tab shows the BCM Nissan Identification part number. Basic Functions can be selected by clicking on the buttons or using the Menu bar. All functions are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

Note: Some vehicles may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. This software does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol.

Self Diagnostics BCM

Self Diagnostics function allows users to read and reset BCM error codes.

Active Test BCM

Active Test allows users to temporally activate some of the functions of the BCM. This is usually used to manually test the functionality of the systems controlled by the BCM.

Note: Functions not supported by the BCM are disabled (grayed out).

OBDII Monitor Status

OBDII Monitor Status shows the current status of various monitoring systems used by the car’s engine management system.

OBDII Log Analyser

Log Analyser is used to review log files previously generated by with Data Logging function. Graphs are drawn by selecting boxes next to parameter value. Graph colours match the parameter value colours.

OBDII Fuel System Satus

OBDII Fuel System Status can be used to check if the car’s fuel system is running in Closed Loop mode.

Fuel systems do not normally refer to injector banks. They are intended to represent completely different fuel systems that can independently enter and exit closed loop fuel. Banks of injectors on a V-engine are generally not independent and share the same closed-loop enablement criteria.

OBDII Data Logging

Selected OBDII parameters can be logged to a file. The data log file can then be analysed using the Log Analyser function.

Due to the slow nature of OBDII protocol it’s recommended to log only the required parameters.

Nissan and Infiniti engineered their cars to be able to detect and sense when the vehicle is either in PARK or NEUTRAL. This is very important when installing a remote start system in your manual transmission Nissan Maxima or Infiniti to avoid the vehicle staring in gear (and causing an unwanted accident). Many folks (even longtime professional installers) do not know about this and therefore do not install remote start systems on manual cars. This is actually very straight-forward to do. 

Please note that the below is for the part where you tap into the Neutral Safety Input on your Remote start unit. You still have to follow the normal directions of installing the alarm or remote start unit. 

When the car is in Park or Neutral, the ECU will see 0-volts. If not at 0, the car will not start. You can easily test this with a multi-meter to confirm as we did. The ECU gets its signal from the Park Neutral Safety switch. It also goes by the name Neutral Safety Switch or Inhibitor switch (they essentially work the same).

The Neutral Safety Switch Wire is usually GREEN/ORANGE on Automatic cars, and GREEN/WHITE on 5/6-Speed Manual cars. You just basically tap into this wire and use it to connect to the Neutral Safety Switch Input on your remote start. Most DEI, Viper, Compustar Remote Start and Alarm systems have this. Once this is done, you will now be able to operate your remote start no different than how it’s down on Automatic Transmission cars. It’s very safe and reliable as the signal is coming from the ECU.

It is strongly recommended that you have experience or work with a professional alarm/remote start installer. Please be very cautious and always verify with a multi-meter when in doubt. If you are doubtful and want to test in gear, put in the last (6th) gear and make sure there are no cars around you. Keep your e-Brake on as well through the whole process.

The car scene can be toxic.

Let me explain why…

Long gone are the days where you can build a car how you want it and not receive negative comments towards you and the car.

Buy a new exhaust? Too loud. Sounds like shit. Sounds like [insert instrument here]. Sounds slow. Why didn’t you go with ABC?

Post dyno numbers up? Fake numbers. You’re going to blow your engine up. Way underpowered. My car makes way more HP. Let’s race. Prove those numbers because they’re obviously fake.

Do some exterior/interior mods? HAHA! Wow that looks horrible. Why did you do that? Who does that to [insert your car here]?

There is no more respect in the car community. Everybody’s prerogative is to berate or throw negative comments at other people who are building/modifying/customizing their car to how they want it. They’re not customizing their car to make you happy.

If you don’t like what somebody posts up about their car, or shows off something they’ve done, why even comment? Why does it make you feel good to put other people down?

Why make remarks to make fun of somebody’s work? They probably thought about what they wanted to do, put in the time and money to do it, and now they have it.

It’s just a show of character on yourself when you can’t even say anything nice about what somebody has done.

It’s an equal show of your character if you make a react on a post that talks down or makes fun of somebody else.

Just let the person who is doing custom work be. Let them enjoy their car. No need to make stupid reacts to what he posts or berate/belittle them.

Be an adult. Act your age.

In the end, I’m going to continue to keep doing me, whether anybody likes it or not. I’m going to do what makes me happy, because in the end, being happy with whatever you decide to do with your car and your build is all that really matters💯

Copy and paste if you agree.

I just picked up my HR heads from Gord Bush who cleaned them up for me and flow tested them. We of course have previous numbers from the non-revup heads that I had Gord Bush port – so let’s compare! Visually looking at the HR heads you can see just how much bigger the intake port is than the non-revup heads, and the numbers prove it – the HR heads flow the same as the ported DE heads (in fact substantially more at low valve lifts). The exhaust doesn’t flow quite as well as the ported DE exhaust did, but it is still substantially better than a stock DE at high lifts.

Stock VQ35DE heads on the flow bench, very similar looking to the HR exhaust ports

Stock DE intake ports on the flow bench, substantially different than the HR

One reason the exhaust flows less at low valve lifts may be due to the fact that the HR has smaller valves. While this may be counter intuitive to those of you that go out there and buy the biggest valves you can, a smaller valve shrouds the combustion chamber less, and in-fact promotes flow at higher lifts. My imagination tells me you want the smallest valve and biggest port you can get away with, without overheating the valve.

Once these HR heads are ported, we should be able to get a decent bit more exhaust flow and hopefully crack the 400whp barrier with shorter intake runners and exhaust runners.

 

NEW YORK (April 2, 2015) – The 2016 Maxima is the 8th generation of Nissan’s iconic 4-Door Sports Car (or 4DSC) – though the term wasn’t coined until the 3rd generation 1989 model. The very first model to wear the Maxima name had an “8” in its name – the 1981 Datsun 810 Maxima. Technically, it was the 2nd generation Datsun 810, but the first official Maxima for those keeping score. For the 1982 model year, the 810 badging was removed and Maxima quickly went on to become one of the best known and most popular Datsuns/Nissans for the next three-plus decades. Here we present an infographic showing all Maxima models through the ages.

Big shout to Rico for spending countless hours in finding a cost-effective solution to coilpacks for the VQ35DE engine. This also works on other models and years.

For those that don’t know, Audi coilpacks are stronger and better than Nissan coilpacks. They add better mpg and more HP/TQ. It works on bone stock vehicles or highly modified vehicles. Just rewire the OEM pigtails to Audi pigtails, plug it in and play!

Nissan Coilpack only has 1 coil. Audi has 2 coils as you can see in the picture below. By having 2 coils it doubles the spark output and can easily handle spark blow out that turbocharged vehicles suffer from. Because it’s outer exterior has a metal body it can dissipate heat ALOT quicker than Nissan rubber which helps with heat cycling. It’s also cheaper than OEM Nissan Coilpacks.

Audi R8 Coil Pack Advantages:

  • 50,000 volts compared to Nissans/Infiniti 30,000 volts.
    • Some measure it with Kv so Nissans coils put out 21Kv while VW coils put out 30Kv
  • Quicker Heat dissipation. (Because of its metal body construction it can quickly dissipate heat. Nissan OEM body is made out of rubber that isolates heat instead of disperses it.)
  • More complete burn of the fuel mixture compared to OEM Nissan which equals to better MPG.
  • Idle Stability Improved
  • NO CEL (Check Engine Lights)
  • BEST PART ABOUT THEM IS THEY ARE CHEAPER $$$ than Nissan OEM yet they are much better.
  • Looks 10000% Cooler than OEM Coilpacks

Now the coil packs price varies due to different name brands. They range from $132-$216 for a V6 engine. Below is the link of the coil packs below so you can see the prices and brands. Doesn’t matter which brand you use, I’ve tested them all and they all make the same exact power.

Finally got my R8 coils installed today and I must say it was definitely worth the time and money I spent. I installed them on my turbo 350z running 15psi with #7 plugs. Car runs so much smoother, especially under boost. It’s a totally different car. I used o2 plugs from a 02/03 Maxima to make the adapters for the plug. Just have to file down the alignment guide on the outside of the blue connector.
