Swaps, Turbos, Buildups / M47 crankshaft to M42

« on: September 21, 2012, 03:21:03 AM »

Thank you for the replies! That's actually very interesting to hear DesktopDave! It's always fun to find someone related to Lithuania or someone who atleast knows there is such a country So I understood that the M47 crank still needs some work done to install, that's ok and thank you for the info! Also, I got my hands on an M44 block (with internals) and head. Would it be possible to swap an M44 head on an M42 block? What modifications need to be done and are there any gains? I've also read, that people use M44 rods with shaved (2.5mm) M44 pistonheads, to gain an approx 1996cc displacement, could that be true?

Hey guys, I'm new to this forum, hope you'll accept me to your team, and help me navigate through discussions! Here's the deal: I have an E36/5 Compact with an M42B18, now the engine (along with the front suspension) was a total bust (head gasket blown, poor piston rings, dire need to change seals, differential, clutch etc.) so I decided to perform a major repair and also add some modifications if possible. So aside from the typical intake/exhaust mods, I have read a few topics about the crank change (m47) and a one-mass flywheel from an M20 installation. I live in Lithuania/Europe, so it's not to hard to find the M47 crank, but my main question is: what pistons (or a combination of piston heads and rods from different engines) should i use, to increase the displacement to at least 2.0l? And will the M20 flywheel just bolt-on fit with the standard M42 clutch? Please don't offer me to "simply swap an m50" because I really like the M42 (also the A/C that came with it ) and I'm just wondering whether it could be improved. Also, it's almost impossible to find the S50/S52 pistons here so you can also scratch those off the advice list . Thank you for your time, I hope I posted in the right topic section.
