This kit requires the Turbo Inlet Pipe and Air Filter included in the kit due to space requirements

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
