For USA MINI models

Intake upgrade from NM Engineering

NM Engineering's intake system is a completely bolt-on 'Open-Air-Box' system which gives you the most abundance and unrestricted 360° of air source compared to OEM's sealed air box. A simple 1/2 hour install will get you quicker throttle response, increased power, and more pronounced engine and turbo tunes!

Elite Performance Tuner from Dinan

The DINANTRONICS Performance Tuner is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture into. It does this without negatively affecting your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems.  

Intercooler uprade from Wagner 

MINI Cooper Competition Intercooler Upgrade from Wagner, the German Specialist in Performance Intercooler and Downpipe solutions. The Wagner Intercooler improves efficiency, lowers combustion temperatures, and reduces power loss from excessive intake temperatures - the net result is more power at the wheels!  Unlike some performance engine upgrades, the Intercooler upgrade actually reduces the thermal loads on the engine because it greatly improves the efficiency of the intercooler over the stock unit.  The lower inlet air tempertures helps to reduce the combustion temperatures which means less heat stress on the internal engine components.

Exhaust upgrade from NM Engineering

NM Engineering exhaust systems are constructed from 100% aerospace quality T304 stainless steel – inside and out. Featuring a proprietary muffler design with an improved DRC System and large diameter metric sized tubing and low restriction stainless steel mufflers. This lightweight exhaust  is carefully designed to reduce weight, provide the famous Mini sound  AND meets State noise restriction standards. Complete bolt on system without any cutting. The system features 70mm tubing with dual 100mm (4") polished tips.

Super Turbo upgrade from JMT

The JMTC Super S turbocharger was designed with the street and track enthusiast in mind.  JMTC started with a huge 50mm compressor and upgraded 9-blade lightened high flow turbine to give you full boost quick and a huge amount of power at the top end.  Designed to maintain the quick response of the original turbo and deliver much more torque and power (as much as 100 hp, more with other upgrades!)

With the factory stock 43mm turbo, the power and torque begins to drop off well before redline.  This Super Turbo delivers high torque in the low to mid-range AND increased power at higher RPMs.  If you are looking for a great street, track, or strip upgrade that delivers full race performance, this is the turbo for you. 

NOTE: Some States (like California) have ever tightening requirements for emissions testing and inspections. Always check your current local regulations on compliance for street use.


Could you point me what should we expect using this kit? hp and torque? Regards,
We don't publish HP numbers, because they are relative. Every dyno is different, every car is different. Same car and a different dyno you could get a difference of 15% between them.

With that said, the super Gen3 turbo upgrade is massive - could delivery up to +100hp or more with the other mods.
