+1 on the procharger. If you haven't though about turbo, go to tmaturbo.com and check it out. Personally i would choose the turbocharging route.
If i had the money and was going to keep my car i would turbo, but i'm lookin at a 98 CBR 600 type bike now so the car will have to go.
Yeah put a 100 shot of nitrous on there for less money with better results and not always under boost. Use it at the track when you need it.
