Go all in if you are going to do it. I did the Dom III and am not pushing the turbo to its potential on Pump gas or really even on Race gas for reliability. I have had my Dom III for 8,000 plus miles, a full season of Drag racing and two Full Road course track days. Canyon runs and Freeway pulls come pretty often as well. I haven't had any motor issues, I didn't want to do pistons because you have to pull the motor to do so. I figure if I am going to pull the motor it is going to be replaced with a www.raw1performance.com track series block and heads. Set my Rev limit to 8,000 rpm, and boost my turbo to its absolute choke line. Till then though I will be stuck with what I have.



You can tell looking at the Dyno that more power can be made with this turbo if we chose to not taper the boost as much as my Peak power holds for nearly 1,000 rpm. But I am on a stock motor so the tapering was necessary.

I was debating on the Element GT52 turbo but decided to go with Blouch because of the Ball Bearing. Not necessarily for spool but BB turbo's have been shown to last longer than Journal bearing. Rotated will be more efficient up top than Stock location. Either way you will be close to your power levels.

FWIW the Dyno I am tuned on Stock STi's make around 205-215 whp. With the map of the above Dyno I was dead even with a Porsche 911 Turbo on Miller Motorsports parks Main straight that is about 3/4 of a mile long, I was just passing the 150 mph mark when I had to SLAM the brakes. So I am a good 480 hp car. A 2006 Corvette Z06 made 20 whp more than I did on this same dyno.
