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 SC7326V pistons?
For the SC7326V pistons, a typical bore clearance of 0.0015" to 0.0025" is recommended. However, this can vary based on the specific application and operating conditions, so it's important to consult with your engine builder for precise measurements.
What compression ratio can I expect with these pistons in my SR20VE?
The SC7326V pistons provide a compression ratio of 9:1 when used in an SR20VE engine. Keep in mind that actual compression may vary based on head gasket thickness and combustion chamber modifications.
Are the SC7326V pistons compatible with high lift camshafts?
Yes, the SC7326V pistons feature deep valve reliefs designed to accommodate high lift camshafts, making them suitable for performance builds that require increased valve lift.
What type of wrist pins are included with the SC7326V pistons?
The SC7326V pistons come with standard wrist pins (part number 866-2250-15CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those looking for enhanced performance.
How should I prepare the piston ring grooves for installation?
Before installation, ensure that the ring grooves of the SC7326V pistons are clean and free of debris. It's advisable to check the fitment of the rings (CPN-3425) in the grooves to ensure proper seating and function.
