I can't beleive our Simon hasn't seen this post yet

Yes he has an ST170 turbo, over 300bhp and does go very, very well indeed. It's got tons of mid-range torque, is super smooth (apart from his gear changes ) and makes a really nice noise on boost too!

I'me sure by tomorrow morning he'll see this so I'll let him explain any of the finer points as he's going to be the man to ask seeing as he's done it, and had the experience of one for the past year now.
