OFFICIAL "What Mods Should I Buy for my Coupe?" Thread
nvm guys did some research and the velocity handle both lower and upper plenum and also eliminates the neccesity to have a plenum spacer which is cool, however do you have to go aftermarket on the intake? I really like my z tube. After getting the kinetix intake manifold (Velocity) i will get stillen headers (Outperforms nismo's R Tune by 3-4 horses and ft/lbs of torque and maybe hks hi power exhuast, UTEC turbo xs engine management system, maybe kinetix hfc's and then a greatttt TUnee!!!!!!!!!!! prolly run me close to 4 or 5 depending on labor but will be wel worth the price, then you can always add a vortech and retune to get super numbers, being careful to keep the hp under 400-450 or so , hopes this helps anyone, let me know what you guys think.

Try G35NYC.com, a lot of those guys are in the NY area, maybe they can help.
HFC's or test pipes, plenum spacer, MREV2 if you have a manual, and Osiris tune
well if your gonna tune anyways i heard you should go with the kinetix, however anyone have a kinetix intake manifold with the z tube?? and can it work with the z tube? If not what CAI should i buy, i really liek my z tube and jwt popcharger
I have the Kinetix manifold. It works best on an FI setup. Don't bother with a CAI since they soak up heat. Z-tube with a custom built intake is the best route IMO.
Alright Ive got all the performance upgrades figured out.. what about visual?
