Darton Sleeve kit Mini N14 Cooper S & JCW

The limits for generation 2 tuning are being pushed further all the time. Increased boost pressures associated with high-powered, tuned vehicles means increased cylinder pressures. For MINI N14 owners aiming to push over 350bhp you may suffer from a warped or cracked block, this Darton MID closed deck solution will prevent this from happening allowing you to push more boost and achieve higher horse power from your N14 1.6 turbo engine.

Darton are at the top of the game when it comes to block strengthening. Darton Sleeves have a huge 130,000 PSI tensile strength compared with a 30,000 PSI tensile strength of a cast iron block. This allows you to run your MINI Cooper S or JCW at higher boost pressures creating more power without running the risk of damaging your block.

The Darton Sleeves use a wet sleeve design that offers better cooling over standard open deck designs. The Darton Sleeves feature ‘Swirl Coolant Technology’ for significantly improved heat transfer in the upper cylinder wall area. This improvement in cooling reduces detonation in the combustion chamber which is one of the most common causes of engine failure among high performance, high horsepower engines.

Please Note: Machining of the Darton sleeves will be required to install pistons.
