Gang,
Few pics of my latest project, twin top mount TT setup, to replace the footwell turbo system I built in 2002. Adam Clayman is helping (f1dyno fame), he built the headers and turbo mounts. GT4094 (94mm) ball bearing turbos. Check out the big honking TIAL wastegates so we can keep that boost under control.
Should be fun!! Will keep you posted on our progress.
Good luck with the buildup. Looks great so far. Are you guys going to coat the headers? If so, how hot of a coating do you need to stand up to the temps the turbo puts out?
Very nice. That is the best looking set of headers I have seen posted on here so far. Keep us posted on the progress, it should be very interesting. Ed

Dave, looks great!
Adam did a nice job on the headers!
Those look like the new Tial 60's, are they?
The 4094 designation for these turbos refers to the exducer on the compressor wheel.
The inducer on the compressor wheel is more like a 67mm or 68mm, right?

You are correct Paolo, these are 67mm turbo's** I'm actually surprised at why he wouldn't go a little larger to the GT42R's in the 74mm size. Many dyno's show them to spool almost as fast as the GT40's for some reason...but with obviously much more kick.

Kevin, I have already sent Dave a PM telling him he has to go bigger!
Those turbos there will move about the same amount of air the 66mm turbos on my sidemount system will move but will have slightly cooler compressor outlet temps since the compressor cover is bigger.
Some 76 GTS's would fit in there nicely like SVS has done in the past!
42's would be nice except the 4" downpipes would be tight to fit back past the 5 primaries going into the collector on each side retaining things like AC and the stock oil filter adapter location.

I went with these turbos because I use the car for a little bit of everything. Road course, autocross, and drag racing. It's a bit of a pain swapping tires and springs all the time, but I like each of them and still want to do all. So I wanted to keep the boost threshold/power as low as I can for autox, then go blast a few respectable 1/4 runs on the next weekend.
I'm very worried about cooling, pics of that setup to come in few weeks. I'm seriously considering adding plugins for external cooling in the pits for autox (used to race a turbo snowmobile and we did this) as the car used to get pretty hot after a run as your not really going that fast.
Guys,
Some changes since I last posted. Went with Precision 74mm Turbos to replace the Gt4094's as they were too small, and went to a gen 3 intake manifold. Making some progress!!
