Well after much looking I've bought a Zetec for the RS. The plan is to keep the standard cams and look for about 155-165 hp.
The engine I have is from a 1996 Mondeo that had done 150,000 kms before being smashed. The guy I bought it off checked it out and ran it before removing and he said it seemed healthy. He was selling it as the class he wants to race in won't allow it in his Anglia. I went to the Pickles auctions a few times but this one came up and ended up working out cheaper (and was easier) than buying a wreck
I have also bought a cam belt kit as they break apparantly.. Cost a lot more than a pinto cam belt [B)]
So anyway I'm gathering parts at the moment.. I'm going to buy Ashley extractors and RetroFord engine mounts. I'm going to modify a CVH sump and make a water rail/thermostat housing. Going to use a pinto clutch (will have flywheel redrilled) and an 8V DOHC starter. ECU will be megasquirt. Also have to sort out the water pump belt, not sure whether I'll fit an idler or a 1.8L water pump.
I'm undecided on induction. I want to keep the brake booster and so I'm not sure throttle bodies will fit. I may use a single throttle body and plenum (similar to std), apparantly these will give 160hp on standard cams with extractors and no cat, but beyond 160hp you need ITBs. I'll have to see how much room there is..
heres a pic of the engine

So thats it! Engine won't be going in for ages but at least the project has begun!
