GT-R R35 Plenum Test Fitment on my VQ37HR

Kingbaby · 05-15-2013, 12:29 AM

OEM Z34/Z33 intake manifold runner is $288

GT-R intake manifold is $650

ChrisUR's adapter runner : $380-$450 range ?

I have no idea how much labor/design/cost was to make this....would be cool if it's under $1000 to upgrade

Nice! When will you be tuning?

roplusbee · 05-15-2013, 07:25 AM

Put me on the list for the adapter please. Now I just need to source a GT-R plenum.

Sign me up for everything excluding the plenum

Chris, absolutely loving the progress being made and assuming I don't have to kill too many babies to afford this, I will be taking one myself.

I do have a big question though.

Have you looked into ways to get the strut bar back? I know the factory one will no longer work with this setup and will require modification at the very least, but just wondering if you had given that any thought.

Thanks, keep up the great work!!!!

Nixlimited · 05-15-2013, 09:21 AM

I wonder if the dip around 5300 rpms is related to a resonance at that rpm. I think seeing whether it is persistent after a tune will give a good indication.

indyn · 05-15-2013, 09:35 AM

there might be little bit more gains with slightly bigger intake plumbing.

But, hats off to OP for taking the time to do this.

Looks like I might be keeping my GTR intake collector since no one want it. ;-)

Put it on. Tune it. Show us what it will do with boost. I'd imagine it would really shine. I want this, but I'm not going to be the guinea pig.

thank you all for the good feedback !

as I have already installed the STILLEN intake piping which is slightly larger than stock there should be enough air flow.

for the strut bar this is one of the next things on the todo list 2gether with getting the car tuned via OSIRIS.

as for pricing I have not yet calculated anything. The only thing I can tell currently is that I have paid well over US$6000 (not taking my time into account) in total to make this conversion happen so I fear it will not go for 200 bucks but is well in the 4digit area.

To be honest this mod is from my opinion for people who have done every possible mod you can do to an NA car or even super/turbocharged it and just want this icing on the cake to make it perfect.

Just to give you an idea only the welding took about 2 hours plus about 3 hours of hand-polish/grind the runners for perfect flow. This part even though it is "only" an adapter to make a plenum from another car fit is very complex (5 axis CNC for radius conversion) and not just a cheap "3 flange plates plus 6 pipes".

Please bear with me with the pricing as my current goal is to make the tune perfect and proof what gain can actually be achieved - after everything is 100% finished, tested and discussed I will offer you a group buy no question.

Thank you !

Chris

Post #368 to my response of selling the plate for $200 (I was jk of course) But his response was towards the price of just the plate. Not everything else included.

I'd love to, but various priorities is keeping me from doing much with my car for the next 1-2 years. Double income would be nice by now lol. The next major phase short of building the motor is 3' exhaust, new fuel upgrades, and possibly change out the intake manifold.
