Guys,
This question has been asked before and I have found various answers. I have been looking at a front entry plenum to go with an FMIC to shorten pipework and neaten things up a bit. GTR throttles/inlets seems to go for cheap money compared to a GReddy inlet for example. I have seen pictures of them fitted to various RB20/25 engines but nothing specific to the NEO engine.
Best info I have found is here,
rb26dett intake manifold and itb's on a rb20 head: RB20 / RB25 / RB26 Forum: Nissan Forums / Infiniti Forums - NICOclub
From what I can see the manifold has the same stud arrangement but not the port arrangement on an RB20. I can easily make up an adaptor plate, and more than likely a fuel rail to run the side feed GTT injectors. If anyone has already done this I would be massively grateful for information or pictures. I know a Greddy inlet would be easier, and cutting off and welding the throttle flange onto the side of the standard inlet cheaper. But the Greddy inlet doesn't work very well with the GTT (and is EXPENSIVE), and a modified standard plenum looks like it will give horrendus flow to cylinder 1 and 2. Plus the standard GTT throttle is stupidly big for both arrangements. GTR inlet solves both problems, plus throttle bodies sound ******* sweat.
If anyone has any info at all it would be great. If anyone is interested in an adaptor plate and fuel rail for their own R33 or R34 I'm sure I could work out a group buy.
Cheers!
