TT57 Chevy is one of the wildest twin turbo's ever created. This NRE 515cid, twin turbo, big block features "one-off" intake, valve covers, and timing cover - all cut from billet. We've reversed the cooling system; running water through the heads first and eliminated the distributor with a Crank trigger ignition. All the plumbing, fabrication, machining, and rigging of the engine was done by NRE. The car is scheduled for the 2007 Riddler Awards. The NRE motor made 1000 hp on pump gas and 1850 hp on race gas.
