From standard street engines to high-speed race motors, the combined expertise of Seven Mini Parts and Mini Mania can help build you the classic Mini engine you've always dreamed about!

Once you find an engine you are interested in, contact us and let our expert Tech Staff help you determine which engine will best fit your needs (and budget!).

About Our 1275 Engines

Our rebuilt 1275cc Power Units are guaranteed for 12 months/12,000 miles from time of delivery. Both the Classic Mini engine and transmission have been rebuilt with our vast experience to ensure the right combination of economy and performance; you get good performance at an economical price!

Transmissions are the rod change linkage-type that uses inboard CV joints and 3.44:1 final drive ratio. (Special order units with the older remote shift and yoke outputs are also available!) Clutch, flywheel, and all covers are in place!

Ready To Install And Run

Built for unleaded gas, these motors should produce between 65 and 75 horsepower (comparable to original Cooper "S") and are an easy connect to your existing intake/exhaust, cooling and electrical systems.

Components Include:
  • Cast iron or aluminum cylinder head, stock valves and 1.25 ratio rockers
  • Cast iron pre-Verto flywheel with stock clutch
  • Street camshaft with standard lifters
  • Simplex timing chain with tensioner
  • Rod Change gearbox with 3.44:1 final drive
