SneedSpeed R53 / R52 MINI Cooper S / JCW Engine Rebuild Kit
Street. Sport. Super Sport. Race.
The R53 W11 is one of the toughest engines to ever come in a MINI, but that does not mean the engine is bulletproof. High miles, heat, boost, worn rings, tired bearings, weak sealing, and timing chain stretch still take these engines out.
The SneedSpeed R53 / R52 Engine Rebuild Kit is built to fix what fails and give you the right foundation for the way you drive.
Every component in this kit is SneedSpeed-selected and matched to work together. No generic bundles, no weak links—if we wouldn’t run it in our own engines, it doesn’t go in the box.
