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 are the recommended bore and compression ratio for the SC7130 pistons?
The SC7130 pistons are designed for a bore size of 87mm (3.425 inches) and a compression ratio of 10:1. Ensure that your engine block is properly sleeved to accommodate these specifications.
What type of engine modifications can these pistons support?
These CP pistons are compatible with oversized valves and high lift camshafts, making them suitable for modified H22 engines aiming for increased performance. Ensure that your engine setup is properly tuned to take advantage of these features.
What is the weight of the SC7130 pistons, and how does it affect performance?
Each SC7130 piston weighs 329 grams. Lighter pistons can improve engine response and reduce reciprocating mass, which can lead to higher RPM potential. However, ensure that your engine is balanced with the full rotating assembly to maintain reliability.
What are the ring specifications for the SC7130 pistons?
The SC7130 pistons use CP rings with a thickness of 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil ring. Proper ring gap settings are crucial for performance and longevity, so consult your engine builder for specific recommendations.
Are wrist pins included with the SC7130 pistons, and what are the options for upgrades?
Yes, the SC7130 pistons come with standard wrist pins included at no additional cost. Upgraded options are available, including the Ultra Duty Pin for those seeking enhanced durability under high-performance conditions.
