My project is nearing completion yet again, so figured I would assemble another build thread to show the world what I did to my poor little 1.8T and what it yielded. If I don't mention it, it's stock AWP 1.8T. I won't get into any of the body, suspension or brake modifications here since it is the 1.8T forum, but the car is very light and is specifically built for SCCA FP Solo competition as well as HPDEs.
For more information on the non-engine modifications, take a look at this thread I started in the autocross forum: http://forums.vwvortex.com/showthread.php?6126117-My-MK4-GTI-Setup-Thread

New Dyno:
Still at 27 PSI with a little more timing up top than before. Performed on a very hot and muggy day at FFE Racing.
Old Dyno:
Was done at 27 PSI with relatively conservative timing. In a couple weeks I'm going to run the same setup on the Dynojet at ForceFed, then from there bring the boost up a little bit (~30) and dial in the timing more. I'm super happy with the fat powerband and driveability of the car so far, just what I was shooting for when I took the leap from stock turbo.
