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 SC7233 offer a compression ratio of 10:1 for the Mitsubishi 4G63 2G engine. For EVO VIII and EVO IX applications, they provide a higher compression ratio of 10.5:1.
What is the recommended bore clearance for these pistons?
For optimal performance, the bore clearance for the CP Pistons SC7233 should be set according to the engine builder's specifications, typically around 0.0015" to 0.0025". Always consult the manufacturer's guidelines and adjust based on your specific engine setup.
Are the wrist pins included with these pistons, and what sizes are available?
Yes, the CP Pistons SC7233 come with standard wrist pins included at no additional cost. The standard pin size is 22mm, with options for upgraded and ultra-duty pins available separately.
What type of ring pack is compatible with these pistons?
The CP Pistons SC7233 are designed to work with the CPN-3386 ring pack, which features a thickness of 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil ring.
Do these pistons require any special machining or fitment considerations?
Yes, the CP Pistons SC7233 may require specific machining such as honing of the cylinder bores to achieve the correct clearance. It's essential to ensure the engine builder checks all clearances and fits the pistons properly to avoid any issues during operation.
