    TTE300 Upgrade Turbocharger

    Introducing our TTE300 performance turbocharger for the 1.8T. Offering 340PS in testing by partners with correct hardware & software, Plug & Play Upgrade with fantastic response and OEM reliability. OEM+

    Engineered & Enhanced

    TTE300 start life from a brand new Genuine BorgWarner K04 turbocharger, we then dismantle and set about upgrading as Turbo Engineers.
    To produce a TTE300 K04 upgrade turbocharger we use a much larger BorgWarner 2280 compressor wheel, chosen because it is highly efficient and light in weight at 36grams for fast response. This compressor also features BorgWarner Extended tip technology giving a compressor map that's very wide, creating extremely high flow for comparative size. We CNC Re-Profile the compressor cover in house to a 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 pipe work to the larger compressor to lower turbulence and maximize velocity. The boost discharge outlet is also ported to again smooth the transition to pipework to reduce turbulence.

    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 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 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. Actuator used is uprated sprung Genuine BorgWarner unit, fitted with our reinforced stainless steel clamps and hardware for trouble free operation. This also can also 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.

    Power/Torque limited as motor issues. R-TECH Remarked on how fast this turbo wanted to spool and area volume of power it gives, maybe best hybrid yet seen.

    Great results looking at moderate boost pressure used.

    Shell 99 (no wmi)
    TTE300 port matched
    Pro4 Relentless manifold
    Airtech intercooler
    Forged rifle drilled rods
    82mm je pistons (1mm bigger than standard)
    bartek low compression gasket
    Full bottom end rebuild
    Full head rebuild including supertech exhaust valves
    Relentless 3inch downpipe decat
    Longlife middle and back box delete
