    Default One more 4hp22 question - and, anyone know where to get 5speed parts?!

    Guys -

    I'm told that the 4hp-22 that BMW bolted onto the m20 engines won't work on the m30's - anyone know definitively if this is true or not?

    Also - looking for sources for parts for the 5 speed conversion. Anyone know where to go?!

    Happy holidays to everyone!!

    Best, Whit

    swap the bellhousing and hook up the kick down cable (may need to get creative as the eh has no cable) and it should work. m20 and m30 have different bolt patterns, if you install the m30's 4hp22eh you would need to figure out how to install and make the computer work that controls it
