Wondering if anybody out there has any kind of dimensions for an EA81 bellhousing? Like the measurements of where it bolts to the back of the engine. Trying to draw up an adapter in Pro-E (CAD program) and cant seem to find any good dimensions to use.

hi,

 they are not just a flat plate type thing, it is precision fitted on dowel pins to the block, and the crankshaft  rear main seal is fitted into it as well, also it seals an inch or so of the rear of the oil pan on the bottom of it.   i think there is a gasket between it and the block  too but can't remember for sure.  it  definately closes off the rear of the block and is integral to it.    anyway point is, it's a lot more involved than the ea82 block plate bell houseing.   dimentions i can't help but someone might send you one to work with, should be plenty of them, ,  there are auto trans ones and manual trans ones , can't say if they are the same or not,, and there are 1.8 ea81 and 1.7 or 1.6 , ea71,  so be aware there are several variations perhaps.

Oh yeah, I understand that, I meant where the engine and transmission mate up. Not the plate where the rear main seal goes.

Trying to make an EJ adapter?if so swap in the 5 spee dual range transmission.
