GT-R R35 Plenum Test Fitment on my VQ37HR

same here - I first wanted to go FI but as I have the 7AT and dont want to upgrade the transmission plus I track the car a lot and am concerned about stability I wanted to max out the NA first. Currently I run headers, cats, exhaust, intake and pulleys and make about 320WHP. The manifold is hopefully the i on the pie which squeezes out the last remaining HPs plus giving a better mid- and end torque. But no question the best benefit will be achieved with this plenum uprade and FI - those guys should see big gains if we made it right.

I will investigate if there is a valve that would suit our purpose. If you have an idea what we could use please feel free to share !

For the fuel no worries. We will make a -6AN Dual Rail Setup with DASH fittings in the front. This is completely customable to match any power level up to 800HP and beyond.

The basic setup for NA cars (like mine is currently) will be an Y-adaptor which is connected to the stock fuel pressure regulator and distibutes the fuel evenly to the two rails (remember only 3 injectors are sitting in a -6AN rail. We have build Supras with over 1000HP which are feed by a single -8AN rail with 6 injectors in it !).

The rails will be build so they can take the stock injectors and also every injector which has the same design on the top end. If required I'm able to match the bore for the injector as you wish as every rail will be hand drilled here in our shop.

As the rails have two ports on each end it is even possible to run two separate lines from two fuel pumps (e.g. if you have the CJM fuel pump assembly) to the rails (one pump for one rail) and make the balacing on the other side to even the fuel pressure.

Our setup will also be compatible with fuel return kits where you eliminate the stock pressure regulator and connect either the Y-adaptor to the adjustable FPR or run two lines from the FPR to the rails directly.

hope you like that answer

Chris
