Classic Mini DIY: New Project Reveal

Our high performance engine has all the features of our standard engine, but comes with a fully ported cylinder head, high compression Cooper S pistons, performance cam, ARP high-strength head studs and rod bolts, and flywheel assembly. Each engine is balanced. Power output will be significantly higher than the standard engine, with a power band between 2000-7000 RPM and a slightly lopey idle.

The same careful assembly practices go into our stock rebuilds as our championship-winning race engines. Included in each package is a fully bored and rebuilt 1275 A-Plus engine, rebuilt rod change transmission with 3.44 final drive, reconditioned one-piece pre-Verto flywheel and clutch assembly.
