You are talking a lot of work

, have to change the oil pump, oil pump drive, aux drive shaft, all the belt pulleys and the dist blanking cap from a 2litre 16v. Pistons will be wrong, resulting in a very low compression (good for boost, check the parts for sale

)
I'm sure I have missed loads of other things, can be done but better just to get a whole engine and drop it in. Steve.
