The kit will also fit the Mk2 and Mk3 Golf Platform Vehicles with a modified rear engine mount 

The manifold will work with the PD150/PD130/PD105 Turbo Inlet Pipe (TIP) along with a PD150/PD130/PD105 Intake Manifold

 The Downpipe is slightly different dependant on what platform you are fitting the kit to, but all fit into the stock position, so will work with most aftermarket Exhaust Systems with a reducer. Please state the OD of your system if you would like the correct size reducer supplying. If not the pipe supplied will be 3"

 This is a true ‘Bolt-On’ Big Turbo conversion that is future proof, as well as being proven to give big power and have perfect daily drivability

Here are just a handful of vehicles with the Turbo Kits fitted:

Stainless Tubular Exhaust Manifold With Billet Collector and Head Flange

If you select a Turbocharger, you will also receive the following:

Brand New Garrett GTB Turbocharger with VNT17 Lever Conversion
Brand New Vacuum Actuator
Laser Cut and CNC Folded Stainless Actuator Bracket

We also have a limited supply of Rebuilt GTB2260VK Turbochargers with MFS Billet Compressor Wheels.
For the GTB Turbo Kit with this Turbo please select the 'NO TURBO' option above. You can then purchase the turbo using the following link:

The only part not included in the kit is a boost outlet pipe. As there are many combinations of intercooler setup, we do not have one definite solution that will suit all builds, normally a 2" silicone 90° bend is all thats required


There are 3 different models of the GTB Turbocharger. There is the GTB1756VK, GTB2056VK and GTB2260VK. All are completely interchangeable, so if you start with the GTB1756VK and decide to upgrade, all you need to swap is the turbocharger unit itself, all the existing pipework will bolt right up. We also now offer the GTD2872VRK turbo. This is the same size turbo used on our Seat Arosa and proven to produce over 400bhp (Without Nos) and over 500bhp (With Nos) with the right supporting modifications. 


Here is a comparison of the various wheel sizes of the popular turbochargers, alongside the GTB and GTD Series turbochargers. Bare in mind that the GTD turbos have the latest 5th Generation VNT System, which is far superior to the previous systems, resulting in quicker spool and lower manifold pressures at high RPMs compared to older Gen Turbo's



Above is also a rough guide to what sort of power you can expect from each turbo, with a comparison to other popular turbochargers. This is assuming you have the appropriate supporting modifications for the individual turbocharger. The power figures are what is considered achievable under 'safe' parameters (Injection Duration, Exhaust Gas Temperature and Exhaust Manifold Pressures). Greater power has been achieved in the past with each setup, but in many cases this was pushing many of the components past their safe operating limits

 GTD2872VRK - Please expect around a 6 week lead time on these turbochargers unless otherwise discussed
