Hello I asked this Question on DSM talk and they pointed me to this site.Anyway I recently built my 420a up with forged internals and all that good stuff. SO now i need the turbo kit and thats when i started to get confused. So before I started buying wrong parts I thought I better ask some questions. I'd like to have about 500 hp. 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!

What is all that good stuff? You dont JUST need forged internals for 500hp. You'll need to make sure all other parts of the motor can handle 500hp and put it to the ground. You will need a built head as well, and LSD and stronger axles(you will snap stock axles with 500hp) a Good clutch Obv. and a ported IM & larger TB, as well as fuel mods such as fuel pump larger fuel lines and bigger injectors. Those are just the things on the top of my head. But Im assuming you have something to Tune with since your going for 500hp! AEM? Megasquirt? any of those? And for your Turbo a .50 will not make 500hp. Id go along the lines of a GTX30 turbo. Also you will want a longer runner turbo manifold, all the cast log manifolds out are not sufficient for that much power. And go with a larger enough FMIC thats sufficient for 500hp IMO Id go with a Bar&Plate type intercooler. Im sure other might chime in on other things you will need or not need.

On my phone now so I will reply with more information later.
.50 compressor means nothing. You need to understand how to match airflow of a compressor to produce the desired HP level. Read Garrett's site and search this section for a post regarding compressor maps.
Again saying ".50" means nothing at all. Read and do the math for airflow and fuel requirements to obtain 500+ bhp.
