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 SC7120X pistons provide for a B16A engine?
The SC7120X pistons offer a compression ratio of 11.8:1 when used in a B16A engine. For a B20 or sleeved B18 block with a B16A or B18C head, the pistons provide a compression ratio of 12.7:1.
What machining is required for the SC7120X pistons?
When installing SC7120X pistons, ensure the engine block is properly bored to 84mm with correct clearance. Additionally, the ring gaps must be set according to your specific application and tuning goals.
Are the SC7120X pistons compatible with high lift camshafts?
Yes, the SC7120X pistons are designed with deep valve reliefs to accommodate high lift camshafts, making them suitable for performance builds that require oversized valves.
What is the weight of the SC7120X pistons?
Each SC7120X piston weighs 268 grams, which is beneficial for reducing reciprocating mass and improving engine response.
What type of wrist pins are included with the SC7120X pistons?
The SC7120X pistons come with standard wrist pins (part number 827-2000-12CP1C) included at no additional cost. Upgraded wrist pins are also available if required.
