To hit 1000rwhp It will cost you about $45K realistically. I just bought a built vette with 800rwhp that has $35K put into it. And that is also how much I paid for it. The car still has stock crank, block, displacement, heads, intake manifold, throttle body, and radiator. Every thing else has been forged or built in some way. Keep in mind my suspension is stock and aside from rotors/pads and SS brake lines the brakes are stock too. If your serious about getting big power and your enlisted you have to buy it built already. Otherwise just get a A&A kit with headers and cat back and a spare set of C5Z rear wheels with 295/35-18" BFG Drag radials on there.
