hey Jas - no other 1.0 turbos on the road yet i think, but i did pop down to Alan Jefferys a while ago to ask about a dyno run, and they've had whoever ended up with your engine etc back in for a set-up and re-map - he said it was runnin about 130hp iirc...
anyways, turbos been done, but a supercharged 1.0, that would be something else!. anyone spotted a subaru vivio in a scrappys lately lol
