The LT77 and R380 gearboxes have been the main two wheel drive gearbox options on the Rover V8 for a long time. However, at their core they are modified Land Rover gearboxes and often don't provide the right experience wanted for a two wheel drive car such as an MG B or kit car. What's more, as time goes on more and more of them are starting to show their age (with even the newest ones being over 20 years old), and parts are becoming harder and harder to get hold of to rebuild them.
But now there are two options on the market for brand new two wheel drive gearboxes. One is the superb and well proven Tremec T5, and new in to us at RPi is a Mazda gearbox kit, recently seen in use and performing excellently on the 4.6 stage 3 MG B GT we've had in our workshop. In our eyes, the Mazda box is now the best value for money gearbox option for almost all two wheel drive Rover V8 powered cars.
