1995-1999 4thgen MAF Upgrade to 350z/370z/GTR or Newer Nissan Maxima MAF (Mass Airflow Sensor)

Community Member Credit: ViperVadim / Eddy

This will allow you to use a newer Mass Airflow Sensor to your 1995-1999 Nissan Maxima.  This upgrade has been available for many years in the Maxima community. The newer MAF sensor is pretty much the same as 90% of the newer Nissan Models. Much cheaper and easier to find. You just need to be sure you also use the newer MAF housing when installing.

You can either get an OEM pigtail or use the one from eBay below. I went with the eBay pigtail which costs around $16 bucks shipped. The most important part is that you follow the pin order (wire colors do not really matter as long you follow pin order).

*********************************
Important Note: In order to properly use this new MAF, your car will require tuning. The car will drive OK but your idle will be off and may fluctuate. If you’re preparing to get an ECU tune using stock ECU, make sure to let your tuner know so new MAF can be factored in.
*********************************

For installing, you just need to match the wires as noted below. Very simple but please proceed with caution.

For reference, once you swap to this MAF… you can use MAF’s from any of the cars below. They all share the same exact MAF which makes this a better option.

1998 Infiniti i30 with Vortech V2 Supercharger and DET Manifold

Credit: HomerMAC

Setup Details:

  • Works on A32 (95-99) or A33 DE-K (00-01)
  • V2 Supercharger with V2 Aluminum plate kit with 3.0″ Pulley
  • Only modification I did was shave 1/2 Diameter off the leg located in the center of the SC on the mounting plate. This was to ensure the 3.0″ pulley didn’t have any trouble with the belt. It was done super clean and you will think it was not modified at all if I don’t mention it. It was done by a machine shop.
  • 2.75″ welded alum. charge pipe with coupler from Blower.
  • 2.75″ to 3″0 Bending reducer to connect to the MAF or whatever
  • Pipes are welded with broken beads at the coupler points to keep them from sliding off.
  • AEM Dryflow filter 9×6″
  • Bending coupler 3.5″ (SC inlet) to 4″ Filter Opening
  • Kenne Bell 8:1 FMU for use with stock injectors
  • DET MANIFOLD: Consisting of lower, middle, upple plenums. It bolts up to the vq30de/dek block. TPS,IACV etc is 4thgen interchangeable. Idle ,start up etc. are flawless and OEM.

2020 vs 2002 VQ35DE Upper Oil Pan Comparison

Community Member Credit: Chris Strasser

There are also two variations of the 2nd Gen VQ35DE engine. A Maxima engine is equipped with EVT ( Exhaust Valve Timing ) and has a slightly higher compression ratio along with larger intake manifold and throttle body (75mm). The Altima engine has a slightly lower compression ratio, and is not equipped with EVT. The intake manifold and throttle body (70mm) are also a bit smaller.

Notes:

  • The OBX V2 headers don’t fit with 2020 upper
  •  I used the 2020 new pan, got new headers made. It’s not a big deal.
  • I just tried to fit a 2020 Vq35 windage tray with a 2002 upper oil pan and it didn’t fit. I had to remove the 2020 one and use the 2002.
  • I used the 2014 windage tray but had to grind a few spots to make it work. It was hitting the ribs in the 2002 oil pan.
  • I believe you remove the one on the motor because the wind tray is built into 02 oil pan.
  • What is the main reason to change the upper and lower oil pans, Is it a height or sensor issue? If it’s just a height issue, can that be solved with the raiser motor mounts? Exhaust issue. Depending what headers/ ypipe you use if they are made for the 5.5 upper oil pan they might not work w the deeper 2nd gen oil pan
  • Bottom line is it’s best to have the correct oil pan that goes to the car
