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 Spool CP Custom RB20DET Pistons offer?
The Spool CP Custom RB20DET Pistons are available with a compression ratio of 9.0:1. This ratio is suitable for a balance of performance and reliability, but always consider your specific engine setup and fuel quality.
What type of gudgeon pins are included with these pistons?
These pistons come with 5310 series gudgeon pins, which are designed for high strength and durability under performance conditions.
Do these pistons accommodate high lift camshafts?
Yes, the Spool CP Custom RB20DET Pistons feature deep valve reliefs that are specifically designed to accommodate high lift camshafts, allowing for improved airflow and performance.
What machining considerations should I keep in mind when using these pistons?
When installing these pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, ring gaps should be tailored to your specific application, especially if you plan to run higher boost levels.
Can I get these pistons in custom sizes or compression ratios?
Yes, Spool offers the option for custom bore sizes and compression ratios for an additional surcharge. It's best to contact us directly for specific requirements and details.
