Theres a garage called Autolink services in Cheadle Hulme (it behind a petrol station, think its BP). The guys that owns it races a n/a cosworth mk2 Escort which he built, he has also been restoring a BDA engined mk1 Escort RS. He's also built a N/A cosworth engine on throttle bodies, for another Westfield owner, which is supposed to have 260bhp ish (apparently it was trying to climb off the rollers at 250bhp)., built a 210bhp 2.0 zetec for another guy and set my front geometry. His work seems good so it may be worth speaking to him.

I could try and get the address and number if you want.
