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 compression ratio for the SC7025 pistons in a D16Z6 engine?
The SC7025 pistons are designed for a compression ratio of 9:1 when used in the D16Z6 engine. This ratio is suitable for a balance of performance and reliability, but ensure that your engine is properly tuned and that fuel quality is adequate for optimal performance.
What machining considerations should I keep in mind when installing SC7025 pistons?
When installing SC7025 pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, check that the ring gaps are appropriately set for your specific application, as this can affect performance and reliability.
Can I use SC7025 pistons with high lift camshafts?
Yes, SC7025 pistons feature deep valve reliefs that accommodate high lift camshafts, making them suitable for performance builds that require increased valve lift. However, ensure that your camshaft selection is compatible with the overall engine setup.
What type of wrist pins are included with the SC7025 pistons?
The SC7025 pistons come with standard wrist pins included at no additional cost. If you require upgraded or ultra-duty pins, you will need to purchase them separately.
What is the weight of each SC7025 piston?
Each SC7025 piston weighs 242 grams. This weight is designed to optimise performance while maintaining durability in high-revving applications.
