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 SC7119 pistons in my B16A or B20 engine?
The SC7119 pistons provide a compression ratio of 10.4:1 when used in a B16A engine. If installed in a B20 or sleeved B18 block with a B16A or B18C head, the compression ratio can be increased to 11.5:1, depending on the specific setup and head gasket used.
What bore size do the SC7119 pistons require?
The SC7119 pistons are designed for an 85mm bore size, which is equivalent to 3.346 inches. Ensure that your engine block is properly machined to this bore specification for optimal performance.
Can I use the SC7119 pistons with high lift camshafts?
Yes, the SC7119 pistons feature deep valve reliefs that accommodate high lift camshafts. This design allows for compatibility with oversized valves and helps prevent piston-to-valve contact during operation.
What is the weight of the SC7119 pistons, and how does it affect performance?
Each SC7119 piston weighs 317 grams. This relatively lightweight design contributes to reduced reciprocating mass, which can improve engine response and overall performance, particularly at higher RPMs.
What type of wrist pins are included with the SC7119 pistons?
The SC7119 pistons come with standard wrist pins (part number 827-2250-16CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking enhanced strength and performance.
