A Garrett GT30R would be great for what you want, but is a good bit outside of your price range. An STC Silver Surfer would probably do nicely for what you want, and is listed for $899 on their website, if you're willing to up your budget just a hair. Remember, you get what you pay for.

 

im willing to pay more i only had that much in my pocket but i can wait till friday till i get paid to up my price to around 1000$ u dont think a gt30 would be to big?

 

It's a hair on the big side for your goals, but not horribly big. It's price tag is way too big for your current budget, though. I'd bet the Silver Surfer would probably be a better match for you, though (and a little cheaper, too).

 

i think im going to go with the silver surfer thanks man

 

If you want more responsiveness get the Hunter from STC. It's 53 lbs/min, capable of 460 whp and is $865.
