H22 Turbo Question?
I need some advice on a turbo for my H22. Here are the goals I'm shooting for. All stock internals, no more than 10psi, and hopefully 300 whp. I'm running a Rev-Hard custom manifold. This is a daily driver, set up for road racing. With road racing I want something that has very little lag. I'd like to be at full boost, 10 psi, by 3500 rpm's. I've decided it's going to be a T3/T4, but haven't figured out the trim yet. I'm leaning towards a T3/T04e, 50 trim, with .63a/r. It has quick spool up time, yet enough to flow decent hp. Any advice would be greatly appreciated.

Re: H22 Turbo Question? (Specail Ed)
try a t3/t4 setup that has a .48 exhaust side, or .63 the most for quick spooling times. do a big compressor small turbine. Usually the best setup. I personally just bought a garrett t3/t04e hyrbrid 60 trim comp/.63 a/r exhaust side.

if i were you i would go with garett's disco potato setup. but instead of 3500 rpm spool, it would most likely be 2000-2500 spool. the thing is if you get a turbo with less a/r's it will lose efficiency at high rpm. what this basically means is you will make say 10 lbs of boost at 3500, then as rpm's climb you are slowly losing boost and hp. an adequate setup would either be a disco potato or a t3/t4 in the right cfm range to not lose top end.
