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 is the recommended compression ratio for the SC7020 pistons?
The SC7020 pistons are designed for a compression ratio of 8.3:1 when used in a B16A engine. For B20 or sleeved B18 blocks with a B16A or B18C head, these pistons can achieve a higher compression ratio of 9:1.
What machining is required for the SC7020 pistons?
When installing SC7020 pistons, ensure that the bore clearance is set correctly according to your specific engine build. It's also important to check and set the ring gaps as per your tuning requirements to ensure optimal performance.
Can the SC7020 pistons accommodate high lift camshafts?
Yes, the SC7020 pistons feature deep valve reliefs that are specifically designed to accommodate high lift camshafts and oversized valves, making them suitable for performance applications.
What is the weight of the SC7020 pistons, and how does it affect performance?
The SC7020 pistons weigh 304 grams each. This lightweight design helps reduce reciprocating mass, which can improve engine response and overall performance, especially at higher RPMs.
What type of wrist pins are included with the SC7020 pistons?
The SC7020 pistons come with standard wrist pins (part number 827-2250-20CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those looking for enhanced durability.
