IS38 Turbocharger Swap Checklist
IS38 Turbocharger Swap

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.

Note: The turbo swap checklist is a work-in-progress and an informal guide.

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.
