U-20T's GTI Big Turbo build

[U-20T]

Hi, figured I would introduce myself and start a thread on my 2011 Autobahn.

My background besides the shop and my VW is in mainly JEEPs. My past build was a very custom regular Cherokee. Then I got my Mk4 and finally the Mk6.

I wanted to big turbo the mk4 very bad but decided to upgrade to an Mk6 since it would be new and fresh. I knew I wanted something different so at 6k on the clock the build began.
