Don't speak to garages that talk utter shit for a start mate. A set of 701 injectors, 195 chip, Cossie fuel pump and a carefull setup atnd you should be knocking on the door of 180bhp.

My brothers FRST was making 210bhp @20psi on a completely standard bottom end with 100k on it. The only reason it's apart now is the body needed a check over and while the engine was out we figured we'd make the most of the oppertunity. Car hasn't missed a beat in the 5 years he's owned it.
