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 can I achieve with the SC7060A pistons?
The SC7060A pistons are designed for two compression ratios: 9:1 for the F20C engine and 9.6:1 for the F22C engine. Ensure that your engine setup, including head gasket thickness and combustion chamber volume, is compatible with your desired compression ratio.
What is the recommended bore clearance for the SC7060A pistons?
Bore clearance for the SC7060A pistons should be set according to the engine builder's specifications, typically around 0.0015" to 0.0025". This may vary based on your specific application, so always consult your engine builder for precise measurements.
Do I need to modify my engine for these pistons?
The SC7060A pistons feature deep valve reliefs to accommodate high lift camshafts and oversized valves. However, you should verify that your cylinder head and camshaft setup align with these features to ensure proper clearance and performance.
What type of wrist pins are included with the SC7060A pistons?
The SC7060A pistons come with standard wrist pins (part number 905-2250-15CP1C) included at no additional cost. Upgraded and ultra-duty pins are available for those looking for enhanced performance or durability.
How should I prepare the SC7060A pistons before installation?
Before installation, ensure that the pistons are properly cleaned and inspected for any defects. It's also important to check the ring gaps and ensure they are set according to your engine's specifications. Additionally, confirm that the pistons are fitted correctly to the connecting rods with the appropriate wrist pin clearance.
