a camshaft will be your biggest bang for the buck. For about 200 dollars, it'll but you at about 200rwhp. Contact me via e-mail at
AF1Doerr@aol.com and I can put you in good hands to get the right camshaft. Also, if you've got the money, get some P&P heads and intakes. Since you need to remove the heads to change the valve springs, you might as well change them out for better ones while they're off, same goes for the intakes if they're off you might as well get better ones. Finally if you have enough money for this, I would recommend getting an underdrive pulley and a Cold air induction kit. These two mods alone will give you about 10-15 more hp, and put you at about 205bhp.
