I am about to tear into my car in the coming weeks. ( I close on my new place in May and will finish the garage before I move in)I Like GeeZ( I have a place in Spring. Close to you now) have a TT car here in Houston. My manifold is diferent than yours. Both my exhaust and intake are a little different. I am considering having my exhaust remade. Mine has a crack in it. I currently have not ran across anyone that has any skills to weld Cast and make it good..... A lot of people say that they can try. I have also noticed that your turbo is different than mine. I have a RayJay unit but it sat for 14 years. It spins good but I want to get it serviced before I push it. Can you give up some specs on your turbo. Have you thought about updating the ignition system? I have been looking passively at the Electromotive XDi stuff.....
Keep us updated I am very interested. I have some TT literature and handouts that I can send you once I get moved into my new place, if you would like them for your records.
