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 compression ratio do the SC7208 pistons provide for the Mitsubishi 4G63?
The SC7208 pistons offer a compression ratio of 9:1 for the 4G63 2G engine and 9.5:1 for the EVO VIII/EVO IX applications. Ensure that your engine's setup and fuel quality are compatible with the desired compression ratio.
What are the recommended machining requirements for the SC7208 pistons?
When installing SC7208 pistons, ensure that the bore clearance is set correctly, typically between 0.0015" to 0.0025" depending on your application. Additionally, check that the ring gaps are appropriately set for your specific engine conditions.
Can the SC7208 pistons accommodate high lift camshafts?
Yes, the SC7208 pistons feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves, making them suitable for performance builds that require enhanced airflow.
What is the weight of the SC7208 pistons and how does it affect performance?
Each SC7208 piston weighs 285 grams. This lightweight design contributes to reduced reciprocating mass, which can improve engine response and overall performance, especially at higher RPMs.
What wrist pins are included with the SC7208 pistons?
The SC7208 pistons come with standard wrist pins (part number 866-2500-18CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking enhanced durability.
