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 compression ratio do these pistons provide for the 4G63 engine?
The CP Pistons SC7263 offer a compression ratio of 9:1 when used with the Mitsubishi 4G63 2G head. If you're using them with an EVO VIII/IX head, they provide a compression ratio of 9.5:1.
What are the recommended machining requirements for these pistons?
When installing the SC7263 pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, check that the ring gaps are properly set to accommodate the specific application and expected power levels.
Can these pistons accommodate high lift camshafts?
Yes, the CP Pistons SC7263 are designed with deep valve reliefs that allow for the use of oversized valves and high lift camshafts, making them suitable for performance applications.
What is the weight of these pistons, and how does it affect performance?
Each piston weighs 298 grams. The lightweight design helps reduce reciprocating mass, which can improve engine response and overall performance, especially at higher RPMs.
Are the wrist pins included with these pistons, and what options are available?
Yes, the SC7263 pistons come with standard wrist pins included at no additional cost. Upgraded and ultra-duty wrist pin options are also available for those seeking enhanced performance and durability.
