Originally a 998cc model, this Austin Mini Cooper boasts a mouth-watering specification featuring a host of the most desirable performance enhancing modifications available. Built by recognised specialists Bill Richards Racing around an 'A+', 73.5mm-bore block, the 1,380cc engine incorporates Omega pistons, Metro Turbo crankshaft and con-rods, ultra light steel flywheel, 12G940 cylinder head casting, large valves, race-type ports, bronze valve guides, high-lift roller rockers, Piper Blueprint 320 camshaft, and ultra-light cam followers. Fuel is fed from twin tanks by an electric fuel pump to the 45DCOE Weber carburettor, which is mounted on a Maniflow manifold, this same company being responsible for the long centre branch exhaust manifold and 2"-bore system.

The transmission features a Jack Knight, close-ratio, straight-cut gear cluster with Quaife limited-slip differential, 3.9:1 final drive ratio and 1.08:1 drop gears. The brakes have been uprated with Cooper 'S' discs and drums, Mintex pads, servo assistance and Aeroquip hoses throughout, while the suspension likewise has been upgraded with negative camber bottom arms and adjustable tie rods at the front; adjustable camber plates at the rear; HiLo kit; Spax adjustable shock absorbers and up-rated suspension bushes all round. The Special Tuning 4.5"x10" alloy wheels are shod with Yokohama A008 tyres. A roll cage is fitted within the original interior, which has been upgraded with extra 'S' instrumentation.

Rolling road tested on 14.5.99 by Peter Baldwin, peak power was produced at 6,250rpm when 136bhp at the wheels was recorded. 'OGC 66D' has covered the standing quarter-mile at Avon Park Raceway in a time of 15.1 seconds, coincidentally the same time Autocar recorded while testing a 5.3-litre V12 E-Type back in 1973!
The Mini was purchased at Bonhams' sale at the Goodwood Festival of Speed in July 2006 (Lot 563), joining a stable of cars belonging to our vendor, an active enthusiast who regularly attends shows and rallies. Since acquisition it has been well cared for, looked after by an in-house team responsible for day to day maintenance.

This ultra high-performance Mini Cooper is offered with a substantial history file of invoices and expired MoTs dating back to 1998, engine build notes, and a V5C document.
