535i_E34_90 0 Report post Posted February 2, 2005 Does the M20 manual G/B bolt up to M50 engine - later version 525 etc. I know engines diff, but wondering if possible, or even close as want to give it as a crack. BMW were awfully unhelpful again......the norm here. cheers Quote Share this post Link to post Share on other sites
gmccormack 0 Report post Posted February 2, 2005 The M20 box will fit the M50 engine, but the combination of a M50 engine with a M20 box will not fit back into a car originally fitted with an M50 engine. The different engines (M50/M20) sit on at different angles in the engine bay, so the mounts cast into the gearbox casing are in a different posistion in relationship to the bellhousing to compensate. For example the M50 engine/M20 gearbox combination must be used if you if you were fitting a E30 with a M50 engine to keep the engine at the same angle as the old M20 engine sat at to avoid any clearance problems. Fitting the M50engine/M20 box into a E34 would push the engine onto the same angle as the old M20 would sit in the engine bay, not a problem for a M20 but could create clearence problems for the wider M50 head and at the very least need custom mounts etc. Quote Share this post Link to post Share on other sites
535i_E34_90 0 Report post Posted February 2, 2005 your the man - than you so much, if thats the case im sure it will fit..... I want to put M20 5 spd behind M50 in 91 525i - I overlaid diagrams of each gearbox and they are almost same, a dowel or two need to be moved - but all good. BMW told me gearboxes diff lenghts, but I'm sure M20 drive shaft etc will fit, with some help from me...... I have a fella keen to buy it, but insists on 5 spd manual, even thou 5spd auto... Hard to please some... He's also willing to pay for upgrades of: Cold Air intake' Extractors Port and Polish manifold Higher diff 3.72 or 4.10 in it Opening up throttle body so will be interesting - good asian fella.......wants as fast car.. sh*t it's quick without any of that...
