SEMA 2008: GM Performance Parts Announces 638-hp LS9 Crate Engine
Yes, you read that right. Starting next fall, you'll be able to buy a supercharged LS9, the heart of a Corvette ZR1, and drop its 639 horses and 604 lb-ft of torque into your Miata, RX-7, BMW E30, or whatever else you can find that'll accept a Chevy V-8 (maybe you might even pick an old Chevrolet!). The kit comes fully dressed, including the ignition system, supercharger assembly, exhaust manifolds, and other parts. GM claims the only add-ons needed are an oil tank (the engine is dry sump), and external coolant tank for the charge cooler, and an ECU/wiring harness. Pricing hasn't been announced, but we're sure it won't be cheap.
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.
