Hi everyone, I've decided to fit a more powerful engine into my 1982 mk3 escort ghia and was going to go down the zetec silvertop road but am thinking of something a little more modern. I've read that the st170 duratec badged zetec will fit without much work needed but have read that the duratec st150 engine will fit and is obviously a lighter engine being alloy and more tunable but which will give me that little bit more bhp? Thanks in advance 😎
