Hidden low in the engine bay is a ginormous PTE 91.5mm turbo that, believe or not, is not able to keep up with the new motor. A thunderous 98mm unit now takes its place, mounted off a set of backward 6.0L truck manifolds. The Ohio Boys were the first to start using these humble roots to fabricate their own turbo kits, coming from the suggestion of Wheel to Wheel Powertrain (their engine builder). Mike also fabricated a 5-inch downpipe and exhaust system, though for street use it gets necked down into a 3-inch bullet muffler. |  |  |
