If I wanted to have an N/A motor ....what would i have to get to get up to about 250hp on my gsr ..i have i/h/e and suspension ..and there are 135k miles on my engine ...ne ideas would be great. thanks

Aggresive cams, cam gears, high compression pistons, mill the head and a good tune; but you still aren't likely to hit 250whp (probably at the crank though).

stage three port and polish the dopest valve job. stage three cams fully built head ,valves ,springs retainers,ext. your tranny light weight fly and a stage 2 or three cluthc.a high flow fuel pump bigger injecters a fuel pressure reg and 12:1 comp pistons on 100 octane.oh yeah diemond cut and blueprinted crank and rods.basicly olot of money.and a good dyno tuner.
