How to spend $3k in mods?

threeseventy

Used forum parts are the best bang for the buck. I'll assume self-install on cooler, intake and cbe because they are really just bolt-ons. UpRev is mandatory after intake and exhaust or you could damage the engine by running too lean plus you can get a 100 Octane map for track days.

Stillen G3 intake $300 shipped, used
Stillen or FI CBE $700 shipped, used
Stillen 25row oil cooler $430 new
HFC's if you can work them into the budget.. Stillen (FTW) Used, installed, $350
Uprev $500ish most places, get a race gas map (take some with you)

OR since the car is not slow to begin with, you could spend the 3K on suspension alone, professionally installed for safety- something like

Hotchkis Sways $500 installed
Swift Springs (since you WILL want to drive it on the street also) $400-450 installed
Wheel Spacers $200 you install
Stainless Brake lines $300 installed/upgraded fluid.
RE-11 Bridgestones or even some Nitto Invo's (installed, price varies)
SPL Rear Camber arms ($300 installed and adjusted during your:
Alignment $100

And you'd really get the most of what the car already has.
