I have Nismo CAI, 5/16" Plenum spacer, Unorthodox pulley set, Megan Racing Headers, Invidia G200 exhaust, I was wondering what else could I do to my car performance wise, without spending more then $500 that would make a noticable diff? Anyone?

 

Test pipes or metallic resonated test pipes, high flow cats, yada yada

 

Fast Intentions is having a sale right now.. look into them, they have quality stuff, and they got the proof to back it up

 

Will the testpipes set off my check engine light? Will HFC's set off my check engine light?

 

used light weight flywheel

thermo gaskets and the coolint valve thing-a-ma-jig (be able to close the coolint tube to heat your plenum)

 

HFC's no .................... Test pipes Yup. But you can trick the car for real cheap so the pipes won't throw a code.

 

You already said it... diff.

If you have a 5AT, call Turbo Toys in Tampa, FL and get a 3.5 pumpkin for about $500 and swap it out. You will notice just as much if not more improvement in acceleration with just that than you did with all your other mods combined.

Or get an ECU reflash.

 

pumpkin?

 

Yup... pumpkin. And I'm not talking about what you carve for halloween.

Do a search for final drive, pumpkin, gears, vlsd, or differential. There is a ton of info for you to learn what it is, how it works, and how it will benefit you.

 

lol you and me both, man.
