GT-R R35 Plenum Test Fitment on my VQ37HR

sorry for the image size - I linked them directly from facebook and was not aware they display in full resolution

the oil cap will get a bit more clearance when the plenum reaches its final position on the upper flange, I hope its enough to open and close it flawlessly otherwise we will revise the design of the lower plenum adapter to push the upper plenum back just a little bit.

the throttle bodies of the GT-R R35 and the 370Z are exactly same - the bolt pattern and the I.D. is a perfect match. Only difference the plastic plenum of our cars use an O-Ring for sealing towards the TB and the GT-R plenum will require a real gasket (OEM Nissan R35).

its correct that the position of the TB is slightly more forward - we tried to push the plenum back as much as possible but you are limited by the rear end of the engine/head, so that is about the max we can go. If you have an aftermarket intakte like STILLEN etc. you easily cut about 2 inch off the piping. For the stock intake with airboxes you should also be able to shorten the piping but that has to be tested later on. To be honest I cant imagine that somebody who is willing to upgrade his/her intake manifold runs stock air intake but you never know
