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 Mitsubishi 4G63?
The CP Pistons SC7203 offer a compression ratio of 9:1 for the Mitsubishi 4G63 2G and 9.5:1 for the EVO VIII/EVO IX applications. Ensure that your engine's setup aligns with these ratios for optimal performance.
What are the recommended machining requirements for these pistons?
When installing the SC7203 pistons, ensure the bore clearance is set correctly according to your engine's specifications. It's also crucial to check ring gaps and adjust them as necessary for your specific application to prevent issues under high performance conditions.
Can these pistons accommodate high lift camshafts?
Yes, the CP Pistons SC7203 are designed with deep valve reliefs, making them compatible with oversized valves and high lift camshafts. This feature allows for enhanced airflow and performance in modified engines.
What is the weight of the SC7203 pistons and how does it affect performance?
Each SC7203 piston weighs 335 grams. The lightweight design contributes to reduced reciprocating mass, which can improve engine response and overall performance, especially at higher RPMs.
What type of wrist pins are included with these pistons?
The SC7203 pistons come with standard wrist pins (866-2500-18CP1C) included at no extra cost. Upgraded and ultra-duty pins are also available for those seeking additional strength for high-power applications.
