Mini Upgrades

From blueprinted 850cc to Fast road 1380cc, we are steeped in experience with the Mini engine and extracting the maximum performance from it. Either with a supplied donor engine, or one sourced by us if required, the Mini engine upgrade process begins with a detailed inspection of each component before a complete chemical clean.

In terms of a Mini engine rebuild, transitioning from the standard Mini engine to our Rob Walker Performance version is a highly detailed and precise process delivering a fully-reconditioned cylinder block and crankshaft, uprated shell bearings, individually-balanced con-rods, top quality Nural pistons, high performance camshaft and followers, high capacity oil pump, uprated gasket, refaced flywheel, and dynamically balanced crankshaft and flywheel assembly.
