Twin turbskies!!

Youll have about 2g in just the rotating assembly for forged, depending on size turbos/waste gates, blow off valve, piping for which ever intercooler air/air or air/water, new converter you'll be up towards $10,000 in parts maybe including efi I would think, can you weld? What exhaust manifolds were you planning to use? Even after the engine is done transmission will need to be built to handle it, better drive shaft, what rear end do you have? Even going LS the price will add up due to getting a Chevy transmission, all the custom mounts, plus controllers for the engine and youll need a tuner for it as well. It can be done just depends on your budget, can get the same results with a single turbo that would cut some cost down.
