Thanks for your responsesguys,
Yeah been looking into doing the conversion and it looks way easier to build a 1.8 zetec turbo, just not sure its going to have the potential I want.

. I'm aiming to get a smoother more drivable engine but with up to 250 reliable bhp!

. also I've seen people using FRST and cosworth management not sure whats best.
Does anyone drive a car with a 1.8 zetec turbo, so they can tell me what it drives and performs like in comparison to a decent spec cvh??
CheeRS!
