Hi Guys.

Just wondering if you guys with S50B32's could check something out for me. I am using a 3.0l ZF Gearbox behind my motor and for some reason it sits on an angle, either that or the motor is not aligned.

Here are some Videos I got, I don't know what my issue is, whether the motor is sitting too far toward the drivers side or whether its positioned OK but tilted slightly causing the gearbox to be out a lot.









Cheers.

I have put some new videos into my original post.

Also I can't see anything twisted or misaligned with the chassis so not suspecting anything like that for now.

I measured very carefully on my car....Just for comparison purpose too for any other people running the same engine. The Front of the throttle shaft is in the same axis with the little notch on the front radiator support like in the below picture. Other photos on the internet I have seen appear to be the same :

Could anybody with an S50B32 E30 check this one out?
I'm just trying to see if it's the position of the motor that is at fault, or whether it's positioned right but tilted slightly toward an angle

I have done the best I can to guess if the motor is sitting where it should and it sort of appears it is, so the only thing I can think of is finding a way to tilt it to the right such as grinding the notch away on one of the exhaust side engine mount to allow that mount to swivel freely on the subframe, the issue is then the position of the threaded stud will not allow the engine to move anymore even if i remove the notch entirely i would have to elongate the crossmember hole which I don't really want to do at last resort.

As the motor sits, with all the nuts on the mounts loosened, I can try force the transmission to get into place but it has a lot of pre-load and wants to just spring back, I don't know if I should lift the motor up from the sump on a jack then try repeat. Whether it could be some odd issue with my e28 mounts batch manufacturing tolerence not locating at proper angle that they should or something else, no idea

Just joined, did you ever sort your problem. Was going to suggest on one side the e28 m5 mount which has offset studs to allow the engine to twist a little to lineup the gearshift.
