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 SC7344V pistons in an SR20 engine?
For the SC7344V pistons, a typical bore clearance of 0.0015" to 0.0025" is recommended. However, it's crucial to verify this with your specific engine setup and ensure proper machining for optimal performance.
What compression ratio do the SC7344V pistons provide for the SR20VE/VET?
The SC7344V pistons have a compression ratio of 12.5:1. This high compression is suitable for performance applications but requires careful tuning and fuel quality to avoid knock.
Can the SC7344V pistons accommodate high lift camshafts?
Yes, the SC7344V pistons feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves, making them suitable for high-performance builds.
What type of wrist pins are included with the SC7344V pistons?
The SC7344V 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 seeking enhanced performance.
What is the weight of the SC7344V pistons, and how does it affect engine performance?
Each SC7344V piston weighs 332 grams. Lighter pistons can improve engine response and reduce reciprocating mass, but ensure that your engine's balance and tuning are adjusted accordingly for optimal performance.
