Dose it matter if the engine i use for a M50 swap is from a E36 auto ?
Do i just fit a manual E36 box on the back of it or can i use my E30 box ?

My engine was from an auto.....Remember we spoke about when fitting gearbox! My ECU has the chassis number of an auto on it and it runs fine Keith

The engine ECU is the same be it an auto or a manual 8)

You can use the E30 gearbox but you will need to fabricate a mount as it will be rotated 10°
No messing with props and diffs though 8)

So all i need to do then to use my exsisting M20B25 gearbox is to rotate the rubber mounts,

Anyone got any drawings/dimensions ?

No, you need to fabricate a new carrier for the rubber mounts because the gearbox when attatched to the M50 engine will be rotated a further 10°

When are you getting it out again ????

How does the 10Deg's rotation affect the gear shift ?

All you need is a vice and some sort of lever and twist the linkage approx 10° in the opposite direction.
That will sort the gear shift
