Recheck the fluid level at temp. If it is good, check the MV2 solenoid, then the EDS3 solenoid. Then move to the orifices in the VB for those solenoids.

ZF Part # 1058-270-036

That is the A drum. I don't have a part number handy, sorry.

At the snap ring? That is par for the course.

IIRC, behind the rubber plugs, are bolts. You need to pull the tube for the diff shaft to see them.

So, about 2540cc. I doubt that the extra 60cc or so would be worth the compromise, IMHO.

Displacement wise? I know there aren't any stroker cranks, but how big can you bore it, realistically, for a turbo motor? Also, has anyone tried this swap in a B5 or C5? I am intrigued by the VR6, but the 5cyl. just freaking sounds cool.
