I have a Precision SC6169E Turbo for sale. It is basically a cross between a gt30r and gt35r. It is not a stock location bolt on turbo, it's for rotated setups only. It is rated at 650hp and has a 4 bolt .63ar hotside. I bought it new and has been on my car for around 12k miles. Very Good condition, absolutely no abnormal shaftplay.
Power numbers were 440whp,405tq at 22psi on a 2.5 shortblock with WRX heads and 93 pump with methanol injection. DynoJet dyno.
Turbo is still on the car right now but will be available within a couple of weeks.
$425 shipped.

Thanks for looking.
