2618 alloy pistons are designed to be racing pistons. Don’t install these in your car or truck, and expect to travel 100,000-plus miles. If the plan calls for serious nitrous, boost, or rpm, and bulletproof is what you are after, a 2618 piston is the right choice.
Do you need forged pistons for a turbo?
With that said, the vast majority of turbo engine builds require forged aftermarket rods. For mild to moderately boosted engines, a good set of forged rods is a must. As with pistons, they are the ultimate in strength.
Do forged pistons make more power?
It is true that forged pistons are heavier than cast pistons, but this is counteracted by the ability to provide a high compression ratio inside the engine, enabling the engine to rev higher and produce more power.
What is a good compression ratio for Turbo?
Today, the average high-performance street or strip turbocharged four-cylinder race engine sports a compression ratio of 9.5:1, with some even running compression ratios as high as 11.5:1 or more on alcohol or E85. Modern technology allows our racing generation to get the best of both worlds.
What’s the best compression ratio for turbo?
Can I put a turbo on my stock engine?
Turbocharging your car’s stock engine will substantially increase the engine’s horsepower potential. However, there are many upgrades you can perform on your stock engine that can be utilized when installing a turbo system in the future, allowing for maximum turbocharged horsepower potential.
How much HP can forged aluminum pistons handle?
Stock cast pistons will limit you to 5800rpm, but cast pistons will hold more than 500hp. It is good to 7000 for forged pistons.
What’s the difference between forged and hypereutectic pistons?
Compared to both 4032 and 2618 alloy forged pistons, hypereutectic pistons have less strength. However, hypereutectic pistons experience less thermal expansion than forged pistons. For this reason, hypereutectic pistons can run a tighter piston to cylinder clearance than forged pistons.
What are billet pistons?
Billet pistons are fully-machined from solid stock. Billet pistons are commonly thought to be stronger and tougher than forgings when in fact, their strength properties are surprisingly similar, with forged pistons holding a slight edge due to the improved grain structure contributed by the forging process.
What kind of pistons does a LS9 have?
The LS9 is the only factory Gen III/IV engine that came equipped with forged pistons from the factory. Nevertheless, because larger-diameter pistons must be used anytime a block is overbored, the virtues and drawbacks of stock pistons are somewhat irrelevant in a stroker motor.
Does the LSA have hypereutectic pistons?
Despite the fact that it’s equipped with a factory supercharger, the LSA comes equipped with hypereutectic pistons. This is made possible by efficient intercooling and advanced engine management software that can retard timing instantaneously, if necessary. Since 2003, GM has applied a polymer coating to LS piston skirts.

Select your preferred location and we’ll note which parts are ready to be picked up TODAY. Summit Racing® Pro LS piston and rod kits deliver industry-leading fit, finish, and durability at an affordable price. These assemblies are tested to over 1,200 hp in turbo applications.
What size nitrous piston do I need for my car?
For moderate doses of boost and nitrous, a 4032 alloy is sufficient, but a 2618 alloy piston is a necessity in heavy-duty power adder combinations. Wiseco pistons are very popular with LS enthusiasts due to their high strength and low weight. These heavy-duty nitrous pistons have a 1.115-inch compression height and weigh 462 grams.
