Forged Pistons for Mitsubishi, 4G63 2G, 86mm, 9:1 or EVO VIII/EVO IX, 9.5:1 (CP Pistons SC7203)

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.

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.

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.

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.

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.

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.

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.

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.
