Mini R53

The supercharged Mini Cooper S R53 (W11 engine) is a firm favourite in the UK club and time-attack scene — and notorious for needing its bottom end strengthening once boost climbs and pulleys come down. Pro-Race Engineering stocks the parts that matter for an R53 build: Wossner forged piston kits, performance H-beam connecting rods, ARP fasteners, ELRING head gasket sets, Supertech valvetrain components, Catcams camshafts and Febi timing chain kits.

We also offer in-house machining for R53 W11 blocks and heads, including sleeving, decking and combustion-chamber work — talk to our engineers on 01621 473023 if you’re planning a high-RPM track build or pulley/cam package and need a parts list specced to your target power.
