Several good resources are available for explaining how to perform an IS20 or IS38 turbocharger swap on a Mk7 GTI (or Golf R).
Links to a few are located further down the page.
I like to have a checklist of tasks to be performed that I can quickly reference while working on my car and mark off the tasks I’ve completed.
Because I have changed my GTI turbocharger a couple of times I have basic familiarity with the tasks to be performed, and I made this checklist to print out and check off as I do the work.
It may contain errors and will likely be revised.
This is Version 2 Send me an email if you find an error or have a suggestion for an improvement.
