Going for broke

^ haha, me too.

Our transmissions cannot handle over 300whp doing anything other than drag runs, and daily driving.

well, knock on wood, but mine has been fine for a handful of track days.

You lucked out I guess, this is the first transmission failure in the life of this car which isn't too bad I guess ( considering ). I grew used to the tall Yaris gears, however now that I have a high rev limit, I may be better off going back to my xA gearing . I am really hoping my Kaaz lsd is ok. Does anyone know detailed info on the Kaaz gearset? Are they stronger? I know the ratios are closer..... but I would want that set more for a strength upgrade.

I have been told that this is the only option that we have with the C50. The only other real option would be to upgrade to a TRD Vitz RS Turbo Transmission however from what I have found from research the only way to get that is to purchase a half cut of a TRD Vitz however also on the same token I have read that they are rare. I will be very concerned myself once my engine upgrades are complete on the tranny holding up, but then again I won't be overly aggressive with it since I am do straight line racing so the stock one might hold up, but I am not holding my breath. I have already burned through 1 tranny and that is with only having 50k stock and 20k boosted (7-9psi) miles on it.
