After swapping my 1998 4thgen Nissan Maxima with a 2020 Gen3 VQ35DE engine, I was not able to use a strut bar. But thanks to some information from Josh and Blandon, I was able to try a 6thgen Maxima Stillen strut bar and to my surprise, it fits 100%. Fits perfect and has no hood clearance issues. This strut bar should work with any VQ35DE swapped 4thgen. No modifications are needed.

Below are the ones I tried that did not fit: 

  • 1995-1999 Stillen Strut Bar (only works with VQ30DE)
  • 2004-2008 Racingline Strut Bar (Does not clear the upper manifold)

Additional Reference (via Blandon’s 4thgen)

Finally got a chance to dyno the swap today. I decided to spring the extra $10 for an AFR reading since my EU is disconnected. Grand total: $30 for two pulls. Same shop/dyno I used for my previous pulls with the 3.0.

Minor changes that might affect readings:

  • New tires 245/50R16
  • Finally had the car aligned after the swap.

Current setup:

  • 2002 VQ35 w/3.0 timing, DE-K Injectors & FPR, return fuel setup
  • Stock 5th gen intake w/ BOMZ  cone filter
  • PFTB
  • NWP BOP
  • NWP 5pc spacers
  • Altima headers w/ 3″ y pipe back
  • VQ30 Spark Plugs
  • Fuel and timing are bone stock, no adjustments made.

Ok, I started with my 5th gen kit and had to use to the 5th gen piping. This piping was nice and clean but I could not use an open air BOV since the MAF was on the uncharged side any air lost thereafter was registered as a leak and the car would stall. It was time to get creative and try to make some changes.

This setup was nice for a very dependable and worry-free boost application, I just think all that piping made the blower choke and not deliver to its full potential, mainly because of all the bends on the piping.

This is the way it is now, it is still not complete but its %85 there

My MAF is not going to stay this way. A member on here(absoundlab) is helping me out with a 3in MAF housing to make the 5th gen MAF capable of registering all the air that is going by. This pic is just the initial mock-up and not the final product, as I said before it’s only 85% done.

As for the supercharger air inlet, I used 3in piping and a 3in Fujita filter to make things work. I had to cut the part of the car where the windshield tank comes up and make the hole bigger to pass the pipe. Cutting this part of the car is not going to hurt it structurally.

This is how the filter sits…..

Don’t know if this was posted before but…I used a DEK fuel rail on a 3.5 to utilize the return line. It was a cheap and easy way out for me since I did not want to go looking for another option and use what I had.

First, I shaved the tabs off my DEK rail and marked the mounting tabs, and trimmed them so the rail would drop in.

Little clearance issue with the UIM, it cleared but touched

I marked it and shaved it down a little

Then I made some brackets to apply pressure to the original tabs that do not line up with the 3.5 LIM to hold it in place.

I think I will cut where I made the red mark in the pic below and put a rubber tube there as it has on the 4th gen fuel rail to give it some more flexibility.

The Mishimoto performance aluminum radiator for the Nissan Maxima is designed and engineered to maximize cooling efficiency, boost engine functions, and protect your car from overheating.

Important Note:

  • Per Mishimoto, the 04-08 Nissan Maxima Performance Aluminum Radiator (part number MMRAD-NIS-08) is not directly compatible with automatic transmission vehicles. It is only a direct fit for the 2004–2008 Nissan Maxima 3.5L with manual transmission.
  • For automatic applications, you’ll need an external transmission cooler. If you choose Mishimoto, you can go with this part number “MMTC-U”
  • You can also purchase your own transmission cooler at your local parts store (usually B&M or Hayden) which works just as well. They are much cheaper in price as well. I paid $40 bucks for mine.
  • There are some 6thgens within 2005-2006 that have a Heat Sink Type Cooler and DO NOT require an external cooler. The easiest way to check is to look at your radiator and see if there are lines going out to the transmission. 

Transmission Info:

  • 6-Speed Manual: 100% Plug and Play
  • 4-Speed Automatic: External Transmission Cooler Required
  • 5-Speed Automatic: External Transmission Cooler Required (Unless it has built-in Heat Sink Cooler)
  • CVT Automatic: External Transmission Cooler Required

Product Features:

  • Full aluminum construction including durable, TIG-welded end tanks
  • Features a two-row, 1.42″ thick, efficient brazed aluminum core
  • Increased fluid capacity and optimal heat dissipation
  • Perfect for use on the street, strip, or track
  • Ideal replacement for an aging and/or clogged stock radiator
  • Efficient temperature regulation for both stock and modified vehicles
  • Includes 1.3 Bar High-Pressure Radiator Cap which effectively raises the boiling point of engine coolant, providing a safer and more efficient system
  • Includes Magnetic Drain Plug to capture any metallic debris/fragments in your cooling system
