Although the factory turbo does a splendid job of forced induction for the Cooper S, there is room for improvement. We are offering two excellent Turbo upgrades have been developed with emphasis on ‘Quick Spool’ for faster response and are suitable for road or track applications.
Mini Mani is offering two Turbo upgrade options for your 2007 MINI Cooper S:
Option 1. K03 SUPER 42 Turbo Upgrade
These units will work with many of your existing OEM components. and are designed to be a No Tuning Required turbo that will deliver ~ +30hp as a stand alone. Additional horsepower is available when combined with other upgrades such as Hi-Flow Intakes, Upgraded Downpipes, Exhausts, and ECU upgrades.
These units use an optimized selection of different turbochargers parts to deliver added durability as well as quick spooling speed.
The Super 42 high pressure high-flow dual scrolling turbo upgrade uses a big 42mm compressor to give you boost that starts early and last much longer than even the JWC turbo. This turbocharger delivers outstanding response with torque and power gains across the entire power-band and the 42mm design gives you extra boost at the top end when you need it most. If you are looking for an extreme street upgrade that delivers full race performance this is the turbo for you. It will deliver great torque, spool early, and last long. For race applications we recommend one of the aftermarket exhaust systems which will allow this turbo to reach its full potential.
Option 2. K04 EXTREME 45R Turbo Upgrade
When we say High flow we mean it! The K04 turbocharge has a larger exhaust turbine which is designed to increase the amount of air flowing though your engine. Since the exhaust turbine is larger it will spool up a little slower but wait until the top end! This means that instead of spooling up at 1800rpms like in the OEM K03 turbocharger the K04 will spool up at 2800rpms to 3000rpms.
The K04 Extreme 45R upgrade high pressure high-flow dual scrolling turbo uses a large 45mm compressor to give you full boost at the top end. This turbocharger delivers the boost at the higher RPM which is perfect for the track, or any off-road application and extreme street applications. The 45mm design gives you extra boost at the top end when you need it most and prevents the torque loss you see with the stock Mini Cooper turbo.
If you are looking for an extreme track, strip, off-road or extreme street upgrade that delivers full race performance this is the turbo for you. It will deliver great torque, and last longer than any other turbo on the market. For ALL applications you should consider installing a high flow / low backpressure aftermarket exhaust system which will allow this turbo to reach its full potential.
The K04 Extreme 45R turbocharger is engineered to be the most reliable and high-performance upgrade turbo for the 2007+ Mini JCW. This is the number 1 upgrade for your JCW and gives you extreme power for all applications above 400hp.
