Hi guys,

What mods can we do to improve our car's performance ? I'm staying NA and don't want to go SC or FI. At the moment, I have intakes, highflow cats, grounding kit, new spark plugs, Splitfire SDIS and cat-back exhaust. I'm not going to bother with headers as I won't be able to install it myself and from what I've read on here that you don't get much gain/benefits for the money you're paying for then plus install cost as well. Are there any other mods that I can do before I go for a tune ? I just want to get it done once, when finished with all the mods and not waste any money as the tuning cost $660 in where I live.

Thanks

 

Plenum mod
Z1 VQ37 Intake Plenum Power Mod 370Z & G37
Motordyne M370 manifold
And I know you didn't say headers, but here's a pkg just for kicks
VQ37VHR 400HP Package

 

AT or MT? Im trying to do the same with mine. I have intake/cats/catback/m370 and Im tuned.

Going with lighter 18" wheels and tires next, since my tires have not been changed and are wasted.

After that,
-3.69 or 4.08 gears
-NST pulleys

 

Elaborate on those coil packs my good man... I'm 6mt with intake/exhaust/hfc/m370 but untuned. .. upcoming mods are clutch and flywheel combo and 4.08 gears. ..

 

It's a 5AT, I actually have the G35 with VQ35HR not a G37. I asked CZP and they told me that mine is good enough, as the M370 intake manifold is basically a VQ35HR manifold that has been modified for the VQ37VHR so it has better airflow or something ?

I really can't tell the difference with the coil packs ? Maybe it's just me used to it, it has been on the car for awhile now haha.
