Forged Pistons for Acura/Honda, B18 Block w/B16A or B18C Head, 81.5mm, 12.5:1 ( (CP Pistons SC7116)

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.

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.

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.

For the SC7116 pistons, a typical bore clearance of 0.0015" to 0.0025" is recommended. This ensures proper thermal expansion and reduces the risk of piston seizure. Always verify with your specific engine build requirements.

The SC7116 pistons have a compression ratio of 12.5:1 when used in a B18 block with a B16A or B18C head. This high compression is suitable for performance applications but requires careful tuning and high-quality fuel to avoid detonation.

The SC7116 pistons come with standard wrist pins (827-2250-16CP1C) included at no additional cost. For higher performance needs, upgraded pins (827-2250-20CP3C) and ultra-duty pins (827-2250-25CP3C) are also available.

Yes, the SC7116 pistons feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves. This makes them suitable for high-performance builds where increased airflow is necessary.

When installing SC7116 pistons, ensure that the cylinder bores are properly honed to achieve the recommended clearance. Additionally, verify that the ring gaps are set according to your engine's specifications for optimal performance and reliability.
