I thing lewis (B19 TRB) is thinking of selling his, has about 300bhp and 350lb torque
Not too sure though.

BMW M3 are well over rated, my boss has one (53 plate) and i recon a 200bhp escort will show it up.

Zetec 16v turbo engines are becoming fairly popular and most engine builders will make one, expect to bay around the 4K mark for a decent build though.
