Mk7 GTI IS38 Swap Install

We swap out the IS20 from my Mk7 Golf GTI and swap in an IS38 off of an Audi S3 (Also in the Golf R). This install takes the car from 280hp and 350ft-lbs to 360hp and 360ft-lbs with my United Motorsport ECU/TCU tune! Swapping turbos on the Mk7 GTI is a really common thing to do. The IS20 has really awesome spool up and response, but it falls off pretty quickly past 5500rpm. The IS38 appears to have almost no change in spool up, but is happy revving up to the 7000rpm redline.

You will need a lot of tools for this installation! It is incredibly important to prime the turbo before starting the car for the first time. I recommend pulling the fuel pump control module fuse in the engine bay and letting the car idle out of gas. This will ensure you can prime the turbo, connect everything back up and allow the car to crank freely, building oil pressure, before having your first start.

It is also incredibly important to have the car properly flashed to the IS38 tune before driving the car. I had my car flashed for the IS38 before I did the swap and babied the car home.
