Now if you have terrible shocks, rubbish tyres and only hook up in 4th gear with "550" miniature ponies from a dynojet, the box will probably last a lot longer.

What trans upgrades or trans swap out there?

With the gearing of the CD009 would the ring and pinion need to be changed from stock to get a similar power band?

yes, you will need the FD 3.909 or change to a Ford 8.8 etc. for lower

there are some older 3.727 Mazda R&Ps out there, but they require adding a bushing to the pinion shaft to mate up with larger ID FD diff bushing.

You might try searching for those things or pm me on the side if it will help.

there are a few BMW DCT 7-spd options now, but they cost more and are more complex to integrate die to the electronics and software.
