Calling m20b25 guys…..
I have been reading through some threads regarding the m20b25 swap and can’t find a definitive answer to a couple of questions
1. In tank fuel pump: keep 320/6 pump or use 318is pump?
2. Swap sump and use original 320/6 sump?
3. Use e30 m20b25 starter? Does this work with the 320/6 flywheel?
4. Use 320/6 water pump? If so why?
5. Machine 320/6 manifold so ports marry up correctly or does this not matter?

Re: M20b25 question
What kind of swap do you have in mind?
Only block and head and use the solex 4A1 (bad idea) or including motronic injection system (much better)?
Carburettors need a low pressure fuelpump, injection system a high pressure pump.
Use the original 320/6 sump
Waterpump, doesn't matter as long as it is compatible with your fanclutch.
And use the m20b25 exhaust manifolds.

Re: M20b25 question
Planning to put the whole engine in
I thought the m20b25 manifold fouls the steering column??
