Sorry, I though you had some suspension mods.
I would put all my money into that. The few ponies you will get with your limited budget, wont make as big a difference as suspension mods like sways bars, and springs would make, plus you'll make the car a hell of a ot more fun to drive. Id concentrate on those first, then add a little more power later if you can.
