For The Ultimate Mini
Ultimate-Mini is able to offer a variety of engine and transmission options to suit every owner. Our custom built range starts from standard engines through to powerful, yet useable, modified units.
All our engines, regardless of specification, are built with meticulous care and attention.
Chose between 998, 1293 or 1380 engine sizes. Each unit is built using components that will suit the way you intend to use the car.
We offer alternative carburation and exhaust options to compliment your choice of engine.
You may choose to go for twin SU's to improve the breathing. These are offered in either 1.25" or 1.5" to suit the engine specification. For the bigger unit, the 1.75" HIF SU is a possible alternative.
For competition purposes, a variety of Weber carburetors can be fitted, including single, split and downdraught configuration.

Each gearbox is reconditioned prior to installation and can be built with the customers choice of differential ratio. We are happy to assist in suggesting which ratio would best suit the use of the car.

For competition use, straight-cut gears are available and limited slip differentials.
