hehe.. which mech is that?
Anyway, M42 is ideal for good weight distribution and with that, it's more agile.. Can throw into the corner with less tendency for it to understeer.. However, it is down on power when compared to the 2.5 liter M50. U'll feel the lack in torque on the M42 as compared to the M50..
Well, can't have best of both world... Depends what you want the car to do more often loh...

Cut the firewall and move the M50 engine 12 inches further back. That should solve the weight distribution problem. While you are at it, might as well put in roll cage, remove the rear seats, install dry sump, etc, etc

Using an alloy block helps...

Yes. M42 is a good option but NOT the best option out there. There are no best option for engine transplant for E30 nor any car for a fact. It always depends how much money you have, how much patience you have and what you want 2 do with the car when it's ready.

Have u sat in a well sorted M42 converted E30? It's a 140hp pump-petrol-and-go engine. I've converted mine 6 years ago, done about 150,000km and no major issues... Daily drive, track days and long distance drives. Not sure what's the mileage of the engine when I got it but i reckoned it should be at least 50,000km. Water pump never need changing. Only changed some oil seals over the years. Just regular service needed. Duplex timing chain, so very little risk of it snapping.
Not the best engine for the E30 but it's one hell of a tough nut... It took all the abuse I threw at it..
M40 to M42 conversion is relatively straightforward compared to M50 conversion.

Hi Alex, how is ur E3024V convertion going on? Mind to tell me which engine oil is best for M52 engine? My M52 can't wait to drop out from it's half dead body and the heartlessly hunger E30 watching and can't wait any longer to get the M52 drop in...

BMW Car Magazine has done a comparison between E30 M42B18 and E30 M20B25. Both has it's characters, strong point and weakness.
The E30 M42B18 is nickname baby M3. It's not fast, but it's very rewarding to drive in a hands of good drivers (like you
). Therefore, it has the fun & wow factor. As for the E30 M20B25, it's also rewarding to drive as the silky smooth 6 pot. Its a rewarding car to drive daily.
