ZR1 In A Box: GM Performance Parts Carting LS9 Crate Engine To SEMAGM Performance Parts has announced the introduction of its 638 HP LS9 crate motor, set to debut at the SEMA show next week. Yep, the supercharged, 6.2-liter heart of the ZR1 can now be ordered without the Corvette wrapper, ready to drop into the bare engine bay of your choice. You get a complete engine including the ignition system, supercharger assembly, exhaust manifolds, dry-sump oil pan and provisions for the intercooler's liquid cooling system — pretty much everything in this gorgeous exploded LS9 view except the 'Vette engine cover. Pricing isn't mentioned, but considering an LS7 crate engine runs about $14k, figure well north of there. Plus a home-built Lamborghini to put it in, of course. Full release below the jump.
GM PERFORMANCE PARTS SET TO UNLEASH THE SUPERCHARGED LS9 CRATE ENGINE LAS VEGAS - The LS9 6.2L supercharged V-8 is the power behind the most powerful and fastest production car in GM's history - the 2009 Corvette ZR1. In the third quarter of 2009, it will be available as a complete crate engine package from GM Performance Parts. It delivers a stunning 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm). The LS9 crate engine will be the ideal all-in package for enthusiasts and racers who want the ultimate LS power plant for their project cars, from resto-modified vintage Corvettes, muscle cars and street rods to late model F-bodies and "shoebox" Chevys. The supercharger and charge cooler are integrated in the engine's valley for a lower profile, allowing creative builders to fit the engine in a variety of applications with plenty of hood clearance. The engine's 6.2L displacement is shared with the LS3, but the LS9 is built for high-revving power with a supercharger. It uses stronger cylinder head castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing. High-rpm-validated lightweight reciprocating parts, including titanium intake valves, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. A new, four-lobe rotor design delivers greater power at the low end and sustains it longer through the rpm band for broad, on-demand power, whether off-idle or at speed. A dual-brick charge cooler is integrated on a unique manifold system that mounts the "blower" in the engine's valley, with charge cooler on top. GMPP's LS9 crate engine assembly comes fully dressed, including the ignition system, supercharger assembly, exhaust manifolds and more. It also includes the production dry-sump oil pan and provisions for the charge cooler's liquid cooling system. Builders will need an external oil tank, external coolant tank (for the charge cooler) and an ECU/wire harness.
