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 are the key features of the ACL Race Series Main Bearings for the Honda F20C1 and F22C1?
The ACL Race Series Main Bearings (5M1913H) feature a high strength overlay plate with reduced thickness for enhanced durability, hardened steel backs for increased strength, and improved fit due to increased crush and elimination of flash plating. They also include 3/4 grooving for optimum oil supply and tight wall tolerances for precision.
Do I need to modify my engine block to use these main bearings?
Typically, these main bearings are designed to fit the Honda F20C1 and F22C1 without modification. However, ensure that your engine block is in good condition and that the main bore is within OEM specifications. It's advisable to check for any necessary machining or clearances based on your specific build.
What is the recommended oil clearance for these main bearings?
Oil clearance for the ACL Race Series Main Bearings should be determined by the engine builder based on the application and intended use. Generally, a clearance of 0.0015” to 0.0025” is common for performance applications, but always consider the specific tolerances required for your engine setup.
Are these bearings suitable for high RPM applications?
Yes, the ACL Race Series Main Bearings are specifically engineered for high RPM conditions, making them a suitable choice for performance builds. However, ensure that your engine is properly balanced and that all components are compatible to maximise reliability and performance.
What type of oil should I use with these main bearings?
For optimal performance with the ACL Race Series Main Bearings, use a high-quality synthetic or semi-synthetic engine oil that meets the requirements of your engine. Ensure that the oil has suitable viscosity for your operating conditions, especially if you are running high RPMs or under heavy load.
