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 SC7138 pistons?
For the SC7138 pistons, a typical bore clearance is around 0.0015" to 0.0020". However, this can vary depending on the specific application and the builder's preferences. Always consult with your engine builder for the best results.
What compression ratio can I expect with the SC7138 pistons?
The SC7138 pistons have a compression ratio of 11.5:1. This is suitable for applications that require a balance of power and reliability, but ensure that your fuel quality and tuning match this compression for optimal performance.
Are the SC7138 pistons compatible with stock L15A VTEC components?
Yes, the SC7138 pistons are designed to work with stock L15A VTEC components, including the factory conrods and cylinder head. However, you may need to check for adequate clearance with high lift camshafts or oversized valves.
What type of wrist pins are included with the SC7138 pistons?
The SC7138 pistons come with standard wrist pins (part number 708-2250-15CP1C) included at no additional cost. If you require a stronger option, an upgraded pin (part number 708-2250-18CP3C) is available.
What machining processes are necessary when installing the SC7138 pistons?
When installing the SC7138 pistons, ensure that the cylinder bores are properly honed to match the piston size and that the ring gaps are set according to your specific application. Additionally, check for any necessary clearancing with the cylinder head and ensure the pistons are balanced with the full rotating assembly.
