Turbo and downpipe upgrade.
My 1.8T quattro recently overheated due to a split coolant pipe and i failed to notice the temperature rise on the gauge until the alarm came up, and i fear that i may have damaged the head. If so, im planning to put a new one on and im going to use it as an excuse to hopefully upgrade the turbo and maybe the downpipe whilst the whole lots off. I was just wondering if the S3 turbo and downpipe are a a direct fit and if not what would be the best way to go about upgrading these parts. Any info would be a great help, thanks.
