Big-Bore Power Units from MINI MANIA for the Classic Mini Cooper & Mini Cooper S

The "Ultimate Street Performance Engine" from Mini Mania is the result of 40+ years of building and racing our own Mini Coopers. Because drivability and reliability are of utmost importance in any Classic Mini Cooper, only components from well-established suppliers are utilized to build our Mini motors.

While the standard configuration is described here, power-units can be customized to meet your particular needs for your Mini Cooper. Just ask your friendly Mini Mania Sales Technician for a custom power-unit quote.

Engine blocks are cleaned, magnaflux'd, bored and painted. The Classic Mini Cooper cylinder head is one of our special Aluminum heads, which is not only cast ported, but has hardened valve seats for use with unleaded fuels. The Mini motor uses Evo  9cc dished pistons, which are specifically designed for this application. Elgin supplies the custom ground camshaft, which is driven by a new timing chain and gears.

The built Classic Mini engine is mated with a gearbox, with flywheel and clutch assemblies all in place. These late model Mini Cooper rod change transmissions are also fully rebuilt and painted, and in the base configuration are assembled with a 3.44 final drive.

Optional kits to install the power-unit in earlier model Classic Mini Coopers are available. An optional remote shift box can be equipped too.

Note: There is NO CORE CHARGE!  And if you want to save even more money, call us about our 'Trade In' Program that allows you to get money back on your old engine!

  • 73.5mm squeeze-cast pistons
  • 10:1 Compression
  • 10/10 Crank
  • Elgin CAM003 carefully timed in at 107º for best horsepower
  • 11-Stud Aluminum Cylinder Head With Big Valves
    These power-units are hand built with care, stand tested and tuned (final tuning, of course, is always done in the Mini). Shipped palletized and protected, the power-units are ready to bolt in and run.

Engines built by Mini Mania are warranted by Mini Mania for 12 months or 12,000 miles (which ever comes from first). Non-refundable $1,000 deposit required.

Let us build you the engine you need! Call us at 800-946-2642 for your customized rebuild.
