Hrm. I will agree with most of the guys on here by saying that if you want a reliable car that can hit solid 12's pass after pass it will cost you. But I do get the feeling that you just meant what would be the most cost effective way of doing it. All I can contest to is that make sure you sit down, write out your stuff because if you are on a strict budget, if will benefit you in the long run. I thought i knew how much It would cost me to put the HCI combo in... HA! I was wrong. By the time you start putting in the small stuff (in my case a TF Gasket kit to ARP Bolts ect) and then the fuel stuff like the Pump, Injectors, MAF ect it really can add up. But Good Luck and let me tell you,
