So I'm making incremental progress on getting my car fixed (spun rod bearing - I'm swapping in a lower-mileage stock M20B25 with refreshed bits). I've searched for some vendors online for a rebuilt t-body but I've had no success. I can recall a time where places like Ireland Engineering or Turner offered these....but neither have them listed on their websites. So who offers this service and what can I expect to pay?
During today's work I made a discovery which some may not be aware of. My car is a 1991 325i 5-speed and the t-body has 1 vacuum port casing drilled for vacuum function. The specific port is located near the mounting flange where it bolts to the intake manifold. When I removed the t-body from the '89 motor, I noticed it has 2 vacuum lines I've posted a couple of photos to illustrate my point.
The upper photo is of the '91 t-body and the lower one is of the '89 t-body. Note that just the lower port casing has been drilled in the upper photo while in the lower photo there's 2 vacuum lines (both ports drilled).
