The Minifilms team have gathered together some of the iconic A-Series engine upgrades to demonstrate how effectively they work and which might suit the modern Mini enthusiast. A magnificent Mk1 Cooper S sets the benchmark, with a remarkable performance in the hands of Mini Miglia champion, Bill Sollis, but it's quickly followed by 1380, 7-port, turbo and supercharged examples of the breed, before being topped off with the most recent A-Series tuning fad, a K1100 BMW cylinder head on the A-series block. Add in a turbo for good measure and you have 230bhp!
