Engineered & Enhanced

TTE360 is an evolution from our TTE340 stage and is based on a brand new Genuine BorgWarner K04 turbocharger, that we dismantle and set about upgrading as Turbo Engineers.

To produce a TTE360 K04(K04 housings K16 turbine) upgrade turbocharger we use a much larger TTE 7+7 billet compressor wheel, chosen because it is highly efficient. We CNC Re-Profile the compressor cover in-house to an optimized tight tolerance and finish to ensure maximum compressor efficiency is given. 7+7 Blade technology enables lower boost threshold giving the user faster spool-up at lower engine speeds while providing the high boost with much less heat for powerful top-end performance.

A key part of driving the large 7+7 compressor and in turn making this unit produce the huge power advantage overstock and also our other stages is machining and fitting a far larger but lightened BorgWarner K16 curved clipped turbine and shaft, while still keeping the K04 core, this is not so easy to do. This K16 turbine gives much lower back pressure and keeps EGT lower compared to stock K04 turbine or clipped stock.

We CNC re-profile the exhaust turbine housing to an optimized profile and gap to take a larger K16 turbine and shaft we use on this stage, this turbine is a Genuine BorgWarner item. We lighten and also give the turbine a 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 backpressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This process also gives a secondary advantage of removing some mass. Lightening the turbine reducing rotational mass, improving moment of inertia, giving faster response.

The intake to the compressor wheel is a CNC milled billet piece with 58mm Dia opening this gives a smooth transition from the intake pipework to the larger compressor to lower turbulence and maximize velocity. The boost discharge outlet is also ported to again smooth the transition to the boost pipework to reduce turbulence.

Attention is given to increase the standard exhaust port size(40mm approx) We CNC mill, porting the turbine housing exhaust and throat and entry size to approx 48mm diameter for maximum flow from an upgraded manifold and so improving efficiency to the bigger turbine used.

Special profile 360 deg high-performance TTE motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response.

The actuator used is uprated sprung Genuine BorgWarner unit, fitted with our reinforced stainless steel clamps and hardware for trouble-free operation. This also can be modified and set to customer needs and specifications if required.


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.
