for turboing it doesn't really matter which, I'd just stick with what you got if it's in good shape. The best thing about f22s is if you blow them they are a dime a dozen at the junkyard

Ok so the whole turbo thing? Hows that work never really payed attention to it?

Is there a brand better than others? is ther a setup up i should aim for or what?

There are plenty of guides online on turboing a car so I won't go into too much detail. But its usually better to piece together a kit than to buy a kit. Turbonetics and GReddy are the only companies that really make whole kits but you usually pay more for these. Garrett is the biggest name in turbochargers.

So buying a turbo kit isnt a good idea? Better to build my own ?

So i was reading some threads and it seems like ill need a new TB and IM before anything ??? Is this correct?
