Genuine GM

The Holden VF HSV GTS ups its performance with an all new 6.2L supercharged LSA engine that delivers 430kw making it second only to the Corvettes LS9 supercharged engine as the most powerful production LS crate engine offered by GM. It is based on the same foundation as the LS9, but with a slightly smaller supercharger and a few other unique components.But just because the LSA doesen't have the same peak power numbers of the LS9 engine doesen't mean it comes up short in any important measurement. The unique aluminum cylinder block casting houses a forged steel crankshaft and super tough reciprocating parts, integrated piston cooling jets, high flow cylinder heads and a relatively mild camshaft with .492" lift on both intake and exhaust sides.The forced induction of the 1.9L sixth generation supercharger makes up for the comparative lack of valve lift by packing the combustion chamber full of air and fuel. This gives the LSA 556 horsepower and 551 Ft. Lbs of torque, along with excellent idle quality and "right now" throttle responce. And unlike the LS9, the LSA comes with a conventional wet sump lubrication system.
