TTE280 T Upgrade Turbocharger VAG 1.8T 20V Transverse K04 Hybrid GOLF GTI / A3 / TT / POLO / IBIZA / OCTAVIA / LEON

Introducing our TTE280 T performance turbocharger for the 1.8T VAG Transverse installation. Offering 280+PS with near Plug & Play fitment.

Engineered & Enhanced

To produce a TTE280 K04 upgrade turbocharger we use a much larger BorgWarner 2283 billet compressor wheel, chosen because it is highly efficient and features BorgWarner Extended tip technology, creating an extremely high flow for comparative size, but giving a compressor map that's very wide. We CNC Re-Profile the compressor cover to an optimised tolerance to ensure maximum compressor efficiency is given.

The intake to the compressor wheel is CNC milled from billet to offer a smooth the transition from the intake pipework to the larger compressor to lower turbulence and maximise velocity.

We CNC re-profile the exhaust turbine housing to accept a larger RS6 size K04 turbine and shaft, a BorgWarner item, and give 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 material, lightening the turbine thus reducing rotational mass, improving moment of inertia.

Special profile 360 deg high-performance motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response. The actuator used is uprated sprung OE unit, fitted with our reinforced clamps for trouble-free operation. This also can also be modified/set to customer needs and specifications if needed.


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.

Product has now been updated for more power and better response. Now has our TTE 9 blade turbine for improved performance.

Bellow is same car, same hardware, tuner and fuel only change was turbo and software adjusted to suit.
