K03 to K04 Conversion

Categories: ,


This turbo is a direct drop in replacement for the K03, fitted to the 2.0 TFSi VAG cars. including the MK5 Golf GTi, Seat Leon, Skoda Octavia VRS & Audi A3 cars.

This turbo will add 100bhp to your vehicle, but that’s not the whole story because the torque increases from 322nm to tarmac shredding 466nm, which is more that the new Porsche 911 Carrera.  With other modifications such as a high flow exhaust and intake system even more is possible.  You can see the improvements on the dyno plot above.

This is a popular conversion for the enthusiast but up until now it caused a few problems as the diverter valve would need to be plumbed in and the air intake would need to be modified to accommodate the closed loop diverter.

It has the K04 internals but the exterior is the same as the K03.  Even the diverter valve is in the correct position making for a very easy installation.

You will need to remap your car to run this turbo.
