I lost my 3rd gear and counter shaft after about 500 boosted and logged runs. Track, street, etc. Considering options rather than just slapping in a used transmission or getting the stock unit rebuilt or beefed up through a vendor like Pineapple.

What options do we have?

Mazdaspeed has their MPD unit that allows gear changes without dropping the tranny. Anyone know how much it costs?

I have noticed that the '84-'87 Ford Bronco II has a similar case (Mazda made) and wonder if it can be used with the FD's 5th gear assembly. Anyone have any information on this?

Intent is to have a multi-use sports car that might be beefier than just stock for occasional 1/4 runs, auto-cross, track sessions at the local round tracks, or general use behind a 500+rwhp engine.

Appreciate your insights. Cost is a consideration, but would like to arrive at a good compromise.

Im going to have mine cyro treated, I dont know how much stronger it will be but the price is pretty good and lots of people have nothing but good stuff to say about cryo freezing.

 

Who is going to do the treatment and the build? How much is the cost? Thanks.
