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 K20A and K24A engines?
The SC70459 pistons offer a compression ratio of 9.6:1 for the K20A and 10.9:1 for the K24A. This makes them suitable for applications where a balance of power and reliability is desired.
What are the recommended bore and stroke specifications for these pistons?
These pistons are designed for an 88mm bore and a stroke of 86mm. Ensure your engine block is properly machined to these specifications for optimal performance.
What is the weight of each piston, and how does it affect engine performance?
Each piston weighs 345 grams. A lighter piston can improve engine response and reduce reciprocating mass, which is beneficial for high RPM applications.
Are these pistons compatible with high lift camshafts?
Yes, the SC70459 pistons feature deep valve reliefs that accommodate high lift camshafts, making them suitable for performance builds that require increased airflow.
What type of wrist pins are included with these pistons?
The SC70459 pistons come with standard wrist pins (part number 866-2250-20CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking enhanced performance.
