What is the difference between the M42 and the m44 engines? I need to replace the engine my m42 E30 318is and would like the best engine to replace it. Having looked on ebay the more common engine is tyhe m44 but I don't want a major problem fitting a non original engine. If someone knows all the differences that would be very usefull in makeing a decision.

Cheers, martin

M44 was fitted to E36 models from 1995, too many issues to be a viable swap.

If you want some fun, the M50 engine is a fairly easy swap (if you are handy with the spanners or know a good garage!)

I am fairly handy with spanners. Do you know a website explaining the steps needed to do the conversion?

Cheers,

I'm sure this PHer

has an e30 318iS with an M44 conversion. Might be worth a mail?

Can feel my ears burning smile

I've not got an m44 sorry. Still got the original rattley 150k m42. People have done the swap but its not completly straight forward. I'm sure someone on e30zone will be able to offer some useful advice. IIRC the m44 is torqueier but less rev happy. Not very scientific I know. The inlet manifold are different. I think the m44 is a 1.9. I think there are also differences between an e30 m42 and an e36 one. Not sure what though.

Apologies if you've sent an email. I can't get into my hotmail acccount so I' not able to reply (or even read it).

Hello there MrF. What you rolling in these days? Still got the MR2?

eta. Just checked your profile. Very nice choice sir. That's an engine that would go nicely in an e30 biggrin

The MR2? Now thats a blast from teh past!

See my profile - but an brief synopsis is that

MR2 --> FTO --> Bugeye Impreza --> Rover 620Ti (dont ask) --> S2000 biggrin

In all honesty the best engine swap I have seen done was a 24valve E46 325 engine and the car went like a rocket and those engines are really nice!!!

It's not too much work but I think it may require an extra bracket!

If you do it your car will be quicker than an e30 original m3!!!
