The 325 engine goes straight in, just keep the inlet manifold, throttle body etc. on the 325 engine.

You'll need the 325 ECU too.

and youll also need to 325i prop as the 320 is different length apart from thats its a straight swap i done one from 320 to 325 in 1 week end and then drove it to work on the monday at the time i didnt realise that the diff caseings were different lol but still done the whole swap in 1 weekend no problem

if your keeping the 320 box all you need is a complete lump and ecu !
providing they are from the same era, pre-face or facelift
