I'd go the other way and try putting it into the car first. Escorts are really short in the front and it will be a big squeeze to get it in. You would need to move the brake booster too as it is where the turbo's will want to live. Let us know how you get on though. I am trying to convince my brother to put a newer engine in one of his Mk1's. Hmmmmm I have a spare 1G too.
