well, warmonger is making 300 fwhp on his 3.0L turbo with only 5.75 psi of boost which is pretty conservative as far as boost goes imho. Hes not running any beefed up internals (yet!

) so i think you might be okay with a stock 3.0L and turbo. But again, doing all that under $6,000 is hard pressed. You might be able to get 250 fwhp on a n/a 3.0L but that would take some serious modding as well. Were talking custom cams, ported and polished heads, headers, the whole shi-bang! If you want 250 fwhp, just spend $1000 and get a venom nitrous kit.
