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 SC7215 pistons provide a compression ratio of 9:1 for the standard application and 9.5:1 for the EVO VIII/EVO IX variant.
What is the recommended bore clearance for these pistons?
For the SC7215 pistons, a typical bore clearance of 0.0015" to 0.0025" is recommended, but always confirm with your engine builder based on specific application and tolerances.
Are these pistons compatible with high lift camshafts?
Yes, the SC7215 pistons feature deep valve reliefs designed to accommodate high lift camshafts, making them suitable for performance applications.
What is the weight of the SC7215 pistons?
Each SC7215 piston weighs approximately 306 grams, which helps in reducing overall reciprocating mass for better engine response.
What type of wrist pins are included with these pistons?
The SC7215 pistons come with standard wrist pins (part number 866-2500-18CP1C) included at no additional cost, with options for upgraded and ultra-duty pins available.
