Introducing our TTE300 performance turbocharger for the MINI. Proven at upto 300ps with correct hardware & software on 98ron, Plug & Play Upgrade with fantastic response and OEM reliability. OEM+
Engineered & Enhanced

TTE300 start life from a brand new Genuine BorgWarner turbocharger, we then dismantle and set about upgrading as Turbo Engineers.

To produce a TTE300 upgrade turbocharger we use a much larger TTE billet compressor wheel, chosen because it is highly efficient and light in weight for fast response. This compressor also features Extended tip technology giving a compressor map that’s very wide, creating an extremely high flow for comparative size. We CNC Re-Profile the compressor cover in-house to an optimized tight tolerance and finish to ensure maximum compressor efficiency is given.The intake to the compressor wheel is CNC milled/ported and hand polished to smooth the transition from the intake pipework to the larger compressor to lower turbulence and maximize velocity. We CNC re-profile the exhaust turbine housing to optimized profile and gap to take a larger K04 turbine and shaft we use on this stage, this turbine is a Genuine BorgWarner item. We also give the turbine special curved clip of a specific amount. The clipping is a TTE grinding process to the turbine blade tips, curved to alleviate stress from the process. Clipping reduces blade area, increasing gas flow and so reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost level’s. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing rotational mass, improving the moment of inertia.Special profile 360 deg high-performance BorgWarner motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response.?The actuator?used is a sprung Genuine BorgWarner unit.


Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.
