The dynamic 1400cc (1380cc) Engines were originally developed in our own Mini's way back in the 1960’s. As you would expect, we have continued to develop and improve these engines making them just as popular for today’s exciting breed of Classic Mini's.
Every 1400cc engine we produce goes through the same meticulous process listed below, ensuring the Mini Sport quality and reliabilty guarantee!
