Mk3 Mini Cooper S for engine rebuild

This unique black and gold Mk3 Mini Cooper S once belonged to the founder of Newton Commercial. Although there are not that many miles on the engine it has not run much in a number of years and is looking a little shabby. We’ve pulled the original Cooper S engine out for a sympathetic rebuild and to be detailed. We also plan to detail the engine bay before it goes back in.

A beautifully presented Mk3 Cooper S came in on Saturday for rolling road tuning. A very rare factory black model with a fresh 1275cc engine and a Swiftune SW5 cam putting out 83bhp.

Mk3 Mini Cooper S engine rebuild

David Mansell brought in a very sad looking engine from his Mk3 Mini Cooper S. “It has been sitting in some rather damp conditions for some 30 years.” Yes, we can tell. The engine has been rebuilt to fast road spec. The bore was increased by .020″ to give 1293cc. A Piper 270 camshaft has been fitted and the cylinder head is getting large valves and a port and polish. The gearbox has had a rebuild and the whole lot painted in the correct satin black.
