Twin turbo, LS1, T56, Blow through Grand National
Heres a little project me a buddy were working on after hours for the shop owner. Its a 87 Buick Grand National. The engine/trans transplant is finished, just need to fab up the clutch pedal, and run all of the lines, also need to build the trans tunnel, since the t56 was much to large to fit in the stock tunnel. We build this from scratch, no kits here. The kit is utilizing stock grand national turbos for now, with external wastegates. Sorry for the cell phone pics.
The downpipes need finished welding. wastegates need welded on, The motor needs pulled one last time, to fix the oil pressure problem, and put in the felpros, and ARP studs.

The transmission is a tremec T56. Its from a Chevy Camaro, Its a 6 speed tranmission. the Engine is a LS1 also from a camaro.
Those two turbos together should barely support about 700hp max. But they are being upgraded.

Where did you get those flanges for the turbine inlet
I need to get one for mine. 700 hp for both, is that at the wheels? I have only one and figured that is about right (350 for one) props for doing something different.
