I'm about to take on the above conversion. I've done a couple engine swaps on e36s with no major dramas, however I'm hearing there's slightly more to getting a 6 pot running in an e46 that was originally running a 4 pot. As far as I can see and from what I've been told, the main issues are going to be the clocks, the throttle and obviously the EWS. Anyone successfully done this swap and able share out of experience?
Hi I'm thinking of doing the same! Landing a 2.5 6 pot in where my n42 is! have you made any progress? A diner car would be the best option! Ive heard you need even the ignition barrel
Progress has been good! Bought engine, broke hand. Progress commences in 6-8 weeks. I can't see how you'll need ignition barrel, surely a diy ews bypass or a remap to the same effect will work. But yeah donor car would be the best option, I won't be doing it that way as I've already picked up an m54 3 litre nice and cheap. I'll be chucking a build thread for it up when my hand is fixed anyways, yours may already be done by that point though aha.
Sorry to bring up an old thread but whats actually involved in this? Is it pretty much plug and play with the engine?
Update on this just in case anyone gives a shit, I've got dash lights and the crank spinning but no further. Should know more later on.
Hi EDD I'm looking for some info on the above conversion, the m54 is fitted and all plugged in and will only crank with the n42 ews module but wont start, and with the m54 ews module I get nothing is there a way of bypassing the ews?
Hi mate, you need to use the m54; ecu, ews module, barrel and key. Alternatively you can open up your keys an swap the chips so you can keep the same barrel. I've not yet figured out bypassing the ews but it's only a ten minute job to change it all over dude. Also worth noting you'll want to change the clocks over too.
How did you get it running in the end bud? I’ve just put a M54 lump where my n42 was and now I’m stuck with wiring the x6004 plug from the m54 dme to the n42 chassis loom, cheers JJ
