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 bore clearance for the SC7016 pistons?
For the SC7016 pistons, a typical bore clearance of 0.0015" to 0.0020" is recommended. This ensures proper thermal expansion and minimizes the risk of piston scuffing. Always verify with your engine builder for specific requirements.
What compression ratio can I expect with the SC7016 pistons in my B18 engine?
The SC7016 pistons provide a compression ratio of 9.8:1 when used with a B18 block and B16A or B18C head. However, actual compression may vary based on head gasket thickness and combustion chamber volume, so it's essential to measure these factors during assembly.
Can I use these pistons with aftermarket camshafts?
Yes, the SC7016 pistons are designed with deep valve reliefs to accommodate high lift camshafts and oversized valves. This makes them suitable for performance applications where upgraded camshafts are used.
What type of wrist pins are included with the SC7016 pistons?
The SC7016 pistons come with standard wrist pins (part number 827-2250-20CP1C) included at no additional cost. Upgraded and ultra-duty wrist pins are also available for those seeking enhanced performance.
What machining processes are necessary before installing the SC7016 pistons?
Before installing the SC7016 pistons, ensure that the cylinder bores are properly honed to achieve the recommended clearance. Additionally, check that the piston ring gaps are set according to your engine's specifications and intended use.
