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 Holden 202 ACL Race Series Main Bearings?
The Holden 202 ACL Race Series Main Bearings feature a high strength overlay plate with reduced thickness for enhanced durability, hardened steel backs for added strength, and increased crush to ensure a secure fit. They also include 3/4 grooving for optimal oil supply and consistent wall tolerances for reliable performance.
Do I need to modify my engine block to use these main bearings?
Typically, the Holden 202 ACL Race Series Main Bearings are designed to fit standard specifications. However, it's essential to check for any necessary modifications or machining based on your specific engine build, as tolerances can vary.
What RPM range are these main bearings suitable for?
These main bearings are engineered to endure higher RPM conditions, making them suitable for performance applications. However, the actual reliability will depend on your engine's overall build quality, clearances, and tuning.
What should I consider when installing these main bearings?
When installing the Holden 202 ACL Race Series Main Bearings, ensure that the engine block and crankshaft surfaces are clean and free of debris. Proper torque specifications for the main caps should be followed, and it's advisable to check the bearing clearances with a micrometer or plastigauge to ensure they meet your engine's requirements.
Are these main bearings suitable for both street and race applications?
While the Holden 202 ACL Race Series Main Bearings are designed for performance and can handle race conditions, they can also be used in street applications. However, the longevity and performance will depend on how the engine is built and maintained.
