Been upgrading my turbo and ignition setup lately. Plan is to get the Audi / VW 1.8t from its current 168 wheel HP to about 300 - 320 HP. Basic plan was to swap in a larger turbo and intercooler then replace the Bosch ECU with a DIY Megasquirt system. A Turbonetics T3 Super 60 turbo and a Tial waste gate have replaced the stock k03 internally waste gated turbo. To get these hooked up I had to get a custom exhaust manifold welded up. On the intercooler side, I removed the small air to air IC installed by Intermeccanica and am replacing it with a full custom intake manifold incorporating 3 Laminova intercooler cores after the throttle body. The TB is an upgrade in size to one from a VR6 VW engine. I'll keep you all posted now that the build is underway. So far the turbos side is done and operates nicely.
