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 engine?
The CP Pistons SC7265 offer a compression ratio of 10:1 for the Mitsubishi 4G64 / 4G63 with a 2G head, and 10.5:1 for those using an EVO VIII/IX head.
What is the recommended bore clearance for these pistons?
For optimal performance, the bore clearance should be set according to the engine builder's specifications, typically around 0.0020" to 0.0025". Always verify with the manufacturer's guidelines.
Are these pistons compatible with high lift camshafts?
Yes, the CP Pistons SC7265 feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves, making them suitable for performance applications.
What type of wrist pins are included with these pistons?
The SC7265 pistons come with standard wrist pins (part number 866-2250-20CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking enhanced performance.
What machining is required for these pistons before installation?
Before installation, ensure that the pistons are fitted with the correct bore clearance and that the ring gaps are properly set. Additionally, confirm that the engine block is machined to the appropriate specifications for optimal performance.
