About our kits
Why the Nissan CG Engine?
Lightweight, powerful, durable and affordable – the Nissan CG is an obvious choice.
As the spiritual successor to the A-Series, despite being a significantly more modern design the CG’s dimensions have remained very close to its ancestor. Even the capacities have remained unchanged at 998 and 1275cc.
Why the Suzuki R7ME Gearbox?
The Suzuki R7ME Jimny gearbox is a compact, durable and modern 5 speed transmission. Weighing only a few kg more than the 4 speed BMC gearbox and fitting a Spridget chassis without any modifications, it is a great upgrade.
Synchromesh on all forward gears and an overdrive top gear transforms how the car drives.
