K360 Hybrid Ko4 Turbo

Direct replacement for the Ko4 turbo

This is a direct bolt on hybrid that will take your K04 car to 360+

Supporting hardware such as B5 Tip, Chinafold ported manifold 550/610cc injectors, front mount intercooler and 3” Downpipe and system is recommended.

Comes with gaskets only.

It is very important a new turbo is supplied with fresh oil and filter when fitted, this gives it the best start from the first key turn – Please see options when purchasing.

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!

The K360 has 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. The wastegate port locking the sleeve to prevent movement (a common issue on this unit)

To ensure fitment is 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. The upgrade actuator is installed with an uprated, stronger spring which ensures fast spool and accurate boost control without boost creep or pre pressure opening.

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.

The K360 is a hand built, bespoke hybrid turbocharger unit, produced and built in the UK.

Custom Dyno calibration is required when installing this turbocharger – please contact us if you would like us to help.
