Like everyone else said, if your going big, go turbo. Cash for top swap then other mods to get up in your desired hp range, your looking around turbo or more. Not including wrench time. Also, if your doing that much hp, you need a beefed up tranny. Your stock tranny won't last long. Triple Edge Performance is your answer. So you could get by with a turbo kit for 2500/3000 depending on turbo, then roughly around 2000 high ball on tranny.
