The Stage 4 Performance Upgrade kit to transform you MINI! This kit blends the racing performance experience of Mini Mania with the demands of the enthusiastic MINI driver.
Designed for the Track oriented MINI, this kit includes components that are NOT STREET LEGAL, and will trigger the Check Engine Light from the O2 sensors (unless you add provisions to cancel the error).
Fits the following Cooper S models:
2007-2013 R56 MINI Cooper S Hardtop
The Kits are different depending on the production date of your R56 Hardtop. There are slight differences with the Intake Kits and the Turbo. Select accordingly.
This kit consists of the K03 Super 42 - Quick Spool Turbocharger and other complementary products to extract the most out of this Turbo.
The Hi-Flow Performance exhaust system from Quicksilver provides a gain in horsepower combined with the right amount of aggressive tones consistent with the performance image of the MINI Cooper S. The Hi-Flow Induction system with their free flowing re-usable air filter allows the engine to develop more horsepower while providing superior protection against dirt and debris, extending the engine life. The Hi-Flow Charge Pipe increases flow by eliminating the OEM sound chamber and increasing pipe diameter over stock. The Turbo Outlet Pipe increases flow by eliminating the intake muffler. The 2.5 inch DE-CATTED Downpipe helps to minimize the backpressure and improves the Turbo's efficiency.
K03 Super 42 - 42mm Quick Spool K03 Turbo Upgrade
This Super 42 Hybrid K03 turbocharger is engineered to be the most reliable and high-performance upgrade turbo for the Turbocharged Cooper S. This can be the number 1 upgrade for your JCW and gives you up to 260 hp. This turbo is designed to be a 'no tuning required' turbo that will add about ~ +30hp, and more with tuning!
This Super 42 upgrade high pressure high-flow dual scrolling turbo uses our big 42mm compressor to give you boost that starts early and last much longer than even the JCW 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 high flow / low backpressure aftermarket exhaust system which will allow this turbo to reach its full potential.
Additional Core Deposit is charged with every Turbo order. Core charges are refunded when a 'Rebuildable' and 'matching' core from your MINI is returned and inspected by the manufacturer.
All or part of the core deposit may be forfeited if the core:
The amount of core refund is determined at the discretion of the Turbo Manufacturer.
Large Bore Downpipe with 3.0 inch pipe diameter produced in high quality 304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers stainless steel may not be) and is less susceptible to discoloration. This quality of stainless steel is used on all pipework and the total construction of the silencer.
Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid range torque. Includes bungs for the O2 sensors.
The larger downpipe provides a greater area for the exhaust gases to expand - ie a greater pressure differential. The Turbo focuses the exhaust energy into the turbine to carry as much energy as possible. As the exhaust exits the turbo and expands, the energy dissipates so the goal is to have the largest area possible for the gas to expand - or a larger downpipe.
On an upgraded turbo, less backpressure equates to MORE HORSEPOWER. The larger the turbo, the more critical this becomes. It may not sound like much, but when you run a larger turbo - it makes a BIG difference!
This 'de-cat' or catless downpipe WILL trigger a Check Engine Light. You will need to find tuner that can modify the ECU software to accommodate the cat-less downpipe.
The tone at idle is nice and deep, similar to a Borla system. The QuickSilver system has slightly more volume throughout the rpm range when compared to the Borla. Definitely not loud or annoying, but a nice sporting sound.
This system delivers on every aspect that our customers have requested:
QuickSilver's newly developed 'Sports' exhaust system for the R56 Cooper S Hatchback is designed to let the 4 cylinder turbo engine breathe more freely and sound great. Customers have reported up to 35bhp performance increase!
Drastic weight reduction - from 40 lbs. to 18.6 lbs! Twin 3" upswept slash cut exhaust tips (DTM style) gives your Mini an individual and assertive look.
Pleasant increase in volume with an encouraging 'Rasp' on acceleration - just right for Urban use.
The 'Open-Air-Box' system gives you the abundance and unrestricted 360° of air source compared to OEM's sealed air box with flat filter and tube fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph. And by logging the Mass Air Flow (MAF) sensor also showed that open-air-box intake generated higher volume (gr/sec) of air going through the sensor. So when we had to choose between (a) cooler air at all speed with limited air source, vs. (b) cooler air at 20~ mph. with unlimited air source, the choice was pretty obvious.
The MINI Cooper S engine utilizes a turbocharger to pressurize the intake tract to force feed the engine air to produce power. As such, a weak point has been identified that impairs the efficiency of this system.
The Hi-Flow Charge Pipe Upgrade replaces the factory necked-down hose between the intercooler and throttle body (cold-side) with a new larger diameter CNC mandrel bent pipe and silicone couplers that will not expand under boost. The system eliminates OEM sound chamber which, in result, helps to increase turbo response as well as mid-range and top-end power.
The R56 MINI Cooper S engine utilizes a turbocharger to pressurize the intake tract to force feed the engine air to produce power. The factory set-up uses an 'intake muffler' with reduced diameter and baffling that prevents 'smooth' airflow.
The Premium Hi-Flow Turbo Outlet Pipe eliminates the intake muffler and replaces the factory rubber hose between the turbocharger and intercooler (hot-side) with a new CNC mandrel bent pipe and silicone couplers that will not expand under boost.
IMPORTANT NOTE: When servicing the Turbo on the MINI, it is very important (maybe even critical) that you replace the Turbo Oil Supply line to avoid potential future turbo issues.
Over time, the turbo and turbo supply line builds a fine layer of 'coked' or cooked oil on the internal surfaces. When you remove the supply line from the turbo, this disrupts the continuity of the coked layer with great potential of some of the coking to flake free. These coked oil particles can easily clog the fine journals that feed oil to the turbo bearings. Once the the oil flow is compromised, it is only a matter of time for cascading failures that can damage the turbo and catalytic converter! Don't take a chance - REPLACE the Oil Supply Line!!
We STRONGLY recommend you change the motor oil more frequently than the factory recommendation. Anecdotal evidence suggests Turbo's with more frequent oil changes have fewer issues. We suggest 7500 mile oil change interval or less.
For additional protection, take a look at the Turbo Oil Supply Line Thermal Wrap.
