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 can I achieve with the SC7113 pistons in my B18 block?
The SC7113 pistons provide an 11:1 compression ratio when used with a B18 block and a B16A or B18C head. Ensure that your engine is properly tuned to handle this compression for optimal performance.
What are the recommended clearances for the SC7113 pistons?
Bore clearance for the SC7113 pistons should be set according to your specific engine build, but a typical range is around 0.0015" to 0.0025". Always consult with your engine builder for precise specifications based on your application.
Do I need to modify my cylinder head to use SC7113 pistons?
The SC7113 pistons feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves. However, it is advisable to check for clearance with your specific setup, especially if using aftermarket components.
What type of wrist pins are included with the SC7113 pistons?
The SC7113 pistons come with standard wrist pins (827-2250-20CP1C) included at no additional cost. If you require upgraded or ultra-duty pins, options are available for purchase separately.
How do I ensure proper fitment of the SC7113 pistons in my engine?
Proper fitment of the SC7113 pistons requires accurate machining of the cylinder bores and careful attention to ring gap settings. It is essential to have the pistons fitted by an experienced engine builder to achieve the best performance and reliability.
