driftfinatic 2 Report post Posted February 12, 2016 Hey guys, Ive got a m73 V12 and im looking at doing a manual swap into a 5 series. I cant seem to find anything in the search about manual conversions for this motor. I realize ecu etc make it difficult but I have a link G4 that hopefully is good enough to run it. My question is what gearbox fits or can be adapted to fit this motor? Its mainly going to be road use but some track days eventually also. Cheers, Conrad Quote Share this post Link to post Share on other sites
kulgan 1042 Report post Posted February 12, 2016 The 850i's used a 560 getrag but your chance's of finding one are pretty slim. Next option would be a 420g which is more than capable but I'm not sure if the fixed bellhousing could be adapted to the back of the V12? I'd also heard somewhere that there had been an adapter made for the Tremec 6 speed though I cant remember where. Quote Share this post Link to post Share on other sites

_ethrty-Andy_ 2132 Report post Posted February 12, 2016 Should have brought my V12 5 series wagon ahh well. Looked into the manual swap budget $6k or so that alone. Are you looking at putting it into E34 or E39 Quote Share this post Link to post Share on other sites
