Re-read what he asked in his post.
He asked the maximum; he didn't say he wanted 600 -- he just said that's what someone else told him. But he should've clarified who told him that..

STEALTH if you do want 600, go find Tino's ride.

Why the fuck are people getting on their horse. It's a bloody question. That's IT!
IF I had any other car and someone told me for xxxxx dollars I'll build you a 600hp car, you'd want to ask people who might know if it's possible that's it. Get on the pills I say and relax. Some of you really need to chill.

350-400 hp at the wheels is achievable with your car if you put a bigger turbo and run E85. You will need a E85 friendly fuel pump and 1000 cc injectors plus a tune for this.

I'm at 356 hp on E85 tune and bigger turbo

The question from the op was:

What's the maximum ball park figure power and torque I'd be able to achieve on an unopened 2.5 06 sti.

The op did not ask how long the sti motor would last at this maximum ball park figure now did he ?
