3000lbs and 400hp?
i dunno man, pretty high goal. but well worth shooting for...
weights going to be a problem for sure, and your turbo is going to be eating itself at psi high enough to make 400.. nitrous may be an idea. shoot some on your I/C core at the same time
also your rear end is gonna be freakin' useless with that much power and quick spool, so give it to me
