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 SC73371 pistons?
The SC73371 pistons are designed for a compression ratio of 11:1 when used with the VQ35HR engine and 10.75:1 for the VQ35DE. Ensure that your engine setup supports these ratios for optimal performance.
What machining is required for the SC73371 pistons?
When installing the SC73371 pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, verify that the ring gaps are adjusted to suit your specific application, especially if you're running higher boost levels.
Can the SC73371 pistons accommodate high lift camshafts?
Yes, the SC73371 pistons feature deep valve reliefs that are designed to accommodate high lift camshafts and oversized valves, making them suitable for performance applications.
What is the weight of the SC73371 pistons and how does it affect performance?
The SC73371 pistons weigh 383 grams each. Lighter pistons can improve engine response and reduce rotational mass, which is beneficial for high RPM applications. However, ensure that your engine's balance is maintained with the full rotating assembly.
Are wrist pins included with the SC73371 pistons?
Yes, the SC73371 pistons come with standard wrist pins included at no additional cost. If you require upgraded or ultra-duty pins, those are available as options.
