I have a 1.3 1989 escort which I think has the HCS engine. The original gearbox sounds like it's going to die imminently, loud whining and what sounds like a grinding bearing in 1st gear. I bought the car with the intent of sticking in an ST170 turboed engine and I've been collecting parts for it. I have an IB5 gearbox already which looks like it has mk6 diesel housing and an LSD fitted, unsure if gears are diesel or not. Question is; will this fit my current engine? From what I've read on here so far I think it will but wanted to check.
