2004 GTO TC78 Build I just bought this car with a maggie on it. I sold it and started my build today. It is going to have a TC78 on the drivers side, 80 lb injectors, 2x walbro 255's, LS6 intake, MS3 cam. The turbo build is going to consist of the stock passenger side manifold with a 2.25" crossover into a log manifold on the drivers side. The log manifold is going to be 3" and then into the turbo. 3" downpipe. Intercooler is 31x12x4. 3" charge piping routed through the frame rails. All piping built by me.
Here are some pics of my progress. More to come...

The log manifold is going to 90 towards the outside of the car and the turbo is going to sit straight ahead with the downpipe pointing towards the rear of the car. My new tc78 will arrive on tuesday. I will mock it up and take some pics of it.

Made some more progress. Got the downpipe finished, LS6 intake and 80lb injectors installed. Going to finish the cross over tomorrow and get it all welded up and wrapped. Purchased some dei titanium wrap with the silicone spray. I also bought HP Tuners to start getting this thing lined out.
