GT-R R35 Plenum Test Fitment on my VQ37HR

ChrisUR

1. well, as the stock fuel rail can't be re-used for fitting issues your choice of two new billet aluminum rails will be included. The smallest rails are -6AN which is slightly more diameter than the stock rails have. I have not tested or evaluated if the stock rails cause any problem but at least it won't hurt.

Of course when it comes to larger injectors you will benefit a lot and as those rails are avail up to -10AN there is much room to grow.

We will use Aeroquip fittings and lines to connect the rails to the stock or an aftermarket FPR - a hard line with fittings will be used to connect the rails from right to left. So it is very easy to run two separate lines to each rail if you want to upgrade to a dual feed system later.

2. yes thats true as the position of the throttle bodies doesnt match the stock location - they are about 5cm / 1.9" more forward towards the front. So if you have like a STILLEN GEN3 you need to cut the pipes by this length to keep the stock MAF sensors in place.

I have a STILLEN GEN3 here myself so when the installation process starts you will see pictures of what modifications are needed. But I try to keep the installation effort as low as and to make this as much PnP as possible.

3. correct, this is "just" the adapter so you are able to install the GT-R manifold. Many people asked me meanwhile if it won't be easier / more effective to do a whole new manifold lower AND upper part together.

Well, of course we could have designed a whole new part and but the idea was to make the GT-R plenum fit the 370Z - that was and still is my personal challenge and whatever comes out at the end of the day I will achieve this goal.

Furthermore our engine and the GT-R engine arent so much different and with the GT-R intake NISSAN developed supports well over 1000HP in the most current setups from tuners like PHR, BL, GReddy, AMS, AAM, etc. - they all keep the stock intake manifold and plenum so I guess and cant be too wrong.

BTW the stock R35 plenum is about $600 new from NISSAN but you can find it around eBay for less than half this price.

1. Will the larger fuel lines/rails/injectors be too much for the 'stock' pump to power for those remaining NA for the time being? Or would it be something that can be included in the maps when getting UpRev tuned?

2. Looking forward for the complete install.


Two thoughts, is this a project for someone considering staying NA to even consider if the possible gain was marginal, and just made a much better looking intake manifold for aesthetics?

Secondly, With the GTR having a different strut bar than the Z, would it be somewhat of a tragedy to get this, and then just be covering the manifold with the stock strut bar? I wonder if there was a way to make another strut bar that would go 'around' the cover vs directly over it...

the strut bar is an important thing to look at but I will start to work on this not before the manifold is in place - I have several solutions in mind but need to see it in reality before deciding what is necessary to make it fit.
