This adapter allows the installation of the BMW M57/N57 engine to a Chevy small block V8 / V6 transmission. It works with both the stock GM 153 tooth or 168 Tooth pre 1985 flywheel/flexplate (two piece rear main seal) and includes a high torque mini starter.
The adapters are not transmission specific, they make the back of the BMW M57/N57 "look" like the back of the engine that the BMW M57/N57 is replacing. The adapters can be used with automatic or standard transmissions 2WD or 4WD.
ALL BMW M57/N57 Adapters are $1,499 USD
and include the mini high torque starter
