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 K20A and K24A engines?
The SC71423XA pistons offer a compression ratio of 12.5:1 for K20A/A2 engines and 14.5:1 for K24A engines. Ensure that your engine is built to handle this compression for optimal performance.
What is the recommended bore clearance for these pistons?
For the SC71423XA pistons, a typical bore clearance of 0.0015" to 0.0020" is recommended. However, always consult with your engine builder for specific clearance requirements based on your application.
Do these pistons require any specific machining before installation?
Yes, the pistons may require specific bore machining to ensure proper fitment. It's crucial to check bore size and ensure that the pistons are fitted to the correct specifications for your engine.
What type of wrist pins are included with these pistons?
The SC71423XA pistons come with standard wrist pins (part number 866-2000-15CP1C) included at no additional cost. Upgraded pins are available separately if needed.
Can these pistons accommodate high lift camshafts?
Yes, the SC71423XA pistons feature deep valve reliefs designed to accommodate high lift camshafts, making them suitable for performance builds that require enhanced airflow.
