Enhanced Turbo Audi/Seat TT Cupra R S3 1.8 20V K04 360 BHP Upgraded Hybrid Billet Upgrade Turbocharger (ET-K360) K04-023 K04-020/022

  • Description

    The 1.8l 20V Turbocharged VAG engine is a cracker. With 210/225HP on tap, this engine gives great power and drivability.

    Our K360 Hybrid Turbocharger has been designed to enhance the original turbo design, increasing power, torque whilst still retaining the fast spooling, punchy power of the OE turbocharger application. 360bhp was the target, and boy did we make it!

    Sitting down with our Hybrid Turbo Design Team, and with the added input from a well respected tuner, we first chose the best possible compressor wheel to flow 360BHP. Once dimensions were decided upon, the wheel’s blade configuration and blade design were next on the agenda. The result is a super lightweight performance billet compressor wheel which - with Increased Inducer Efficiency (IIE), Extended Exducer Technology (EET) and streamline hub - gives unparalleled flow for the wheel size. The 7/7 blade compressor configuration with differing splitter heights not only gives the flow, but also ensures surge is held back to allow maximum power even at low rpm.

    We were determined to ensure the turbocharger’s turbine side of the unit did not ruin the drivability of the car, or indeed hold the car back; the tall blades in a 9 blade configuration ensure this is the case. We increased the size whilst keeping it compact and, most importantly, in the original housing without resulting in dangerously thin walls from over-machining. We also clip the turbine wheel back to aid flow without destroying the spool and low down power. We also upgraded the wastegate port locking the sleeve to prevent movement (a common issue on this unit)

    We wanted to ensure fitment was as near to a genuine original BorgWarner turbocharger as possible, so through the whole design process we constantly compared against the original, although to allow the airflow to be capable of our 360BHP requirement, we have had to produce housings with a larger intake, as such a larger intake pipe will be required on installation.

    The turbocharger boost control is upgraded too. Our upgrade actuator is installed with an uprated, stronger spring which ensures fast spool and accurate boost control without boost creep or pre pressure opening.

    As with all of our Enhanced Hybrid Turbochargers, the bearings are upgraded to our 360 hardened large pad race thrust bearing to ensure they are capable of sustaining the increased boost levels without affecting the hybrid turbocharger’s reliability.

    Being a hand built, bespoke hybrid turbocharger unit, produced and built in our UK production centre, our attention to detail passes not only though the assembly phase, but also onto the turbo balancing phase, where we balance our hybrid turbo upgrade units to motorsport tolerance, giving imbalance levels that are less than half of the level of the original. There are no production time limits, no hourly production quotas, just a technician with a love of turbochargers building a performance hybrid turbo unit that the best it can be! In tests, the most common feedback we get is this is, “The best turbo on the market for 360BHP”.

    If you have a 1.8 20V 210/225BHP then this Hybrid Turbo is perfect for a good daily driver with 360bhp on tap.

    What does it take to make 360BHP?

    We would love to say it’s just the turbo, but it’s the whole “package” of the turbo and other upgrades that sees the best results.

    Turbo – Enhanced Turbo Hybrid 360BHP Turbocharger

    Turbo Inlet pipe – Enlarged Turbo Elbow (54mm required)

    Intercooler – Upgraded Intercooler (stage 3 spec)
