5 Speed Gearbox Conversions

Having decided it was perhaps time to hang up my helmet, I wanted to make my Sebring replica, JJO, a little more comfortable to drive on Britain's crowded public roads - with a 286 cam it could be a pig especially when held up in traffic and the motor regularly overheated. So, part of that plan was to install a 5-speed gearbox and a higher diff ratio so that the car will (hopefully) cruise comfortably at around 2500/3500 r.p.m. without too much fuss. I have always fought shy of chopping the chassis in order to install such replacement 'box but so many people have now done it without apparent ill-effect that I decided to go along with it. In September (2013) a Toyota "Starlet" conversion was advertised for sale on mgcars.org and I was able to do a deal with the seller. Subsequent investigation revealed it to be a T50 'box from an early Toyota Celica (rather than a Starlet) and of 1977-79 vintage with bell-housing of unknown origin, but with a new clutch plate and a propshaft to suit.

Another, now more popular conversion uses the Ford Sierra (Type 9) gearbox for which a separate page will shortly be created.
