Hello Paganis, and welcome here m8!

As I already told you, here you are in the right place for answers on any E21 question.
I can't answer to your question (I haven't any experience with swaps, well...yet :lol: ) but I am sure that many in here will be able to.

hope you have fun in here, and discover useful things. Happy posting!!

yes its been done before - you need to fabricate mounts, and use an m20 engine gearbox.

this period...i have made ,,,a lot of research...about the engine swap
i haven' t found anything , for the m43...but there are severals informations about m42 swap..
the m42...and m43,,,are not so diferent...so i think...that i can do it...the same way...
i will use the m20 gearbox...and a m42 oil pan from a e30..i will fabrikate mounts...and try to make it work...

i have no idea why your doing the m43 because im very sure that engine made 120hp maximum - you can get that very easily with standard m10.

unless your planning on turboing but then again you would get the same with m10 engine and m10 engine would be way more simple.

i have a complete engine swap of a m43...and a handmade supercharged kit...with a root type m65 eaton compressor..at about 200hp ..It is all the power i need..for my track day car...
i know...that i can do the same to the m10...but i feel better to programme something more modern...with my perfect power smt7 piggy back...
