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 benefits of using ACL Race Series Main Bearings in my G4KC G4KD G4KG G4KJ engine?
ACL Race Series Main Bearings are designed for high-performance applications, providing enhanced durability and reliability under higher RPM conditions. Their high strength overlay plate and hardened steel backs contribute to increased strength, making them suitable for both 4, 6, and 8 cylinder setups.
Do I need to perform any specific machining when installing these main bearings?
Yes, it is essential to ensure that the main bearing journals are properly machined to achieve the correct clearances. You may need to check the fitment and potentially line bore the main caps after installation to ensure optimal performance and longevity.
What is the significance of the 3/4 grooving feature on these main bearings?
The 3/4 grooving on the main bearings ensures an optimum oil supply to the crankshaft, which is crucial for maintaining lubrication and reducing wear during high-performance operation. This design helps to improve oil flow and cooling, especially under demanding conditions.
How do I ensure proper fitment of these main bearings in my engine?
To ensure proper fitment, verify that the main bearing housing is clean and free of debris. The tight, consistent wall tolerances of these bearings should provide a good fit, but it's advisable to check the bearing clearances with a micrometer or dial gauge to confirm they meet your engine's specifications.
Are these main bearings suitable for both street and race applications?
While ACL Race Series Main Bearings are primarily designed for race applications due to their enhanced durability and performance characteristics, they can also be used in street engines that require higher reliability and performance. However, ensure that your engine is properly tuned and maintained to maximise their benefits.
