    Background:
    I started my journey with DSM's in summer of 2000 after purchasing a 99 GS Anniversary Edition off the lot. I turbo-charged that car in short order and drove it for roughly 5 years until I decided to make the jump to the 4G63 platform. I was searching for an X13 GSX, but came up short and settled on an X13 GST. The car is currently is setup with a mild street build. Future plans involve swapping the car to the GSX I always wanted and then running more power through it via a larger turbo and more robust fuel / engine management system.

    We gotta get together when the weather breaks, maybe do cars and coffee. Your GST is a very similar build to my Tsi atm, although I have no plans to convert her to awd.

      I would have left it as a GST, but I like going to the track too much and I'm sick and tired of spinning wheels and trying different strategies to get it to hook up. I figured it I was gonna spend 1k on a Quaife, I might as well buy a donor car.
