depending on how loose of a converter you want (2500, 2500, 4000, and up stall speeds), you'll have heating issues and extreme slippage to deal with. Just remember that you're basically dealing with a small block (engine) and a heavy car. A typical converter for this application would be a 10 inch converter for street use.....upwards of a 7 or 8 inch converter for serious drag racing. Big block engines typically flash higher stall speeds than small block engine.

However.....once you get to the point of playing drag racer with the 928, the rear suspension becomes the limiting factor. There's nothing back there to limit wheel hop, broken axles, suspension pcs pulling away from the sheetmetal attachment points, etc.....

if you really want to push the envelope, a trans brake would be next, with a reverse pattern shift.

You might send an inquiry to John Winters (Rockledge, FLA). He is the guy for powerglide trannies in the drag racing community, and may possibly be able to use that technology to build you a converter using the OEM unit as a model. I would imagine the only parts he would need are the front hub and internal drive spines for the input shaft of the tranny. He has a website (JWPerformance or something like that) or you can find his ad in most drag racing publications.....
