Mk3 Mini Cooper S engine rebuild

Another classic Mini 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. Additionally 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 was rebuilt and the whole lot painted in the correct satin black enamel.

Classic Mini engine building service

The BMC ‘A’ Series engine is one of our specialties, having built and raced Sprites, Midgets and Minis for years. Road, rally and full race engines, we can build to your required specifications. We currently have two Mini engines in the assembly shop. One will be a ‘A+’ road engine, the other a fast road small block showcasing all that the 60’s tuning companies had to offer. This little 998 has been bored out to 1040cc and will receive a genuine Speedwell Alloy head and Shorrock supercharger. This will all sit on top of a magnesium cased Colotti 5 speed gearbox. Should be a lot of fun.
