Cale 36 Report post Posted August 14, 2008 Hey Peeps, Wondering what would be involved in putting an M42B18 into a ex-M40B18 E30? Would everything need to be changed i.e. ECU etc.? Does a Getrag 240 bolt up to a M42? If it is easy enough (to get hold of engine, aswell as transplant), it would be 18kW more than the M40 and have similiar fuel consumption. And I have never seen a 318iS Touring. Chur Quote Share this post Link to post Share on other sites
Silver Fox 43 Report post Posted August 14, 2008 you'd need to change the whole lot incl ecu and loom, and do the manual conversion thing, M40 box don't fit sorry. Quote Share this post Link to post Share on other sites

Silver Fox 43 Report post Posted August 16, 2008 Getrag 240 from a M40 318 will not fit. Not so certain on the 240 from a M20 motor, maybe someone else knows? Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted August 16, 2008 all m20 m50 m40 boxes swap around the difference is the angle that the motor sits on depending on the chasis . but they all have the same bellhousing size . Quote Share this post Link to post Share on other sites
Gus 5 Report post Posted August 16, 2008 i dont see why the m40 240 wont fit, as the m42 240 fits on the m40. they have slightly different driveshaft lengths. andys 260 is cut and re-welded. i got a 6spd for it instead Quote Share this post Link to post Share on other sites
