So did your T/A arrive yet? I got my car back and it's running great. I need to find a way to adjust my clutch pedal though. Its adjusted to the top of the pedal and the shop said the adjustable master cylinder has been adjusted all the way down................so basically it cant get adjusted any lower.
And its already shifting at the top of the pedal. Its very annoying. Its grabbing hard though.

i'd say 360 to the wheels. Without a good set of heads, he's going to be very limited. He's going to need a good set of heads to get him to 400. Throw on a 90mm setup and he'll be around 410-420 with a good tune.

Depends strongly on the tune. Don't see a ported TB or UD pulley either. With a razor sharp tune, he's looking at 385-395 rwhp. Add the other components and the power should rise another 10 rwhp.

I'm right at 345 area(don't have slip here) with mods in sig before the stall converter. If I had a M6 I would be over 360 rwhp, so I'd say it should be over 385rwhp. These cars can vary so is hard to tell.
