No more then that though! So what size turbo and intercooler would I probobly need? Will a turbo with a .50 compressor and a .63 exhaust turbine reach that high? Sorry If my post is a little sloppy I just woked up and whanted to post this before I left for work. Thanks!

First of all, if you want any good help from the mods of this site, I would advise you to use spell check as they are very anal about spelling and grammar. 500 hp for your engines requires a lot of work and money. Your looking at, at least a 20g turbo witch is a little bigger than a 60-1 trim turbo. All turbos vary of course. Also you will not be using a SFMU or an FMU, your looking at a megasquirt EMS or a 8 injector setup for your fuel setup. The problem I had with having a megasquirt is tuning, many of the shops around me do not know how to tune it or don't want to.

In my opinion, if your just looking for something fast to drive in, max out the sfmu setup at around 300hp give or take. If you still want 500hp, look for an evo or a subie, or something other than a 420a! Hope this helps!
