What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the recommended compression ratio for the SC7264 pistons?
The SC7264 pistons are designed for a compression ratio of 10:1 when used with the Mitsubishi 4G64 / 4G63 2G head. For applications with the EVO VIII/IX head, the compression ratio is 10.5:1.
What is the weight of the SC7264 pistons?
Each SC7264 piston weighs 306 grams. This weight is important for maintaining a balanced rotating assembly, especially in high-performance applications.
What type of wrist pins are included with the SC7264 pistons?
The SC7264 pistons come standard with wrist pins sized at 22mm. Upgraded and ultra-duty pins are also available for those seeking additional strength.
Do the SC7264 pistons accommodate high lift camshafts?
Yes, the SC7264 pistons feature deep valve reliefs that are designed to accommodate high lift camshafts, making them suitable for performance builds with oversized valves.
What machining considerations should be taken into account when using SC7264 pistons?
When using SC7264 pistons, it's crucial to ensure correct bore clearance and set appropriate ring gaps as per your engine's specifications. Proper machining will help achieve optimal performance and reliability.
