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 Conrod Bearings in my 2AZ-FE engine?
ACL Race Series Conrod Bearings are designed to enhance durability and performance, particularly in high RPM and racing applications. Their high strength overlay plate and hardened steel backs provide superior support, making them ideal for engines under stress.
Do I need to modify my engine to fit these conrod bearings?
Typically, these conrod bearings are designed to fit the standard specifications of the 2AZ-FE engine. However, always ensure that your conrod journals are within OEM tolerances and check for any required machining to achieve proper clearances.
How do I ensure proper oil supply when using these bearings?
The ACL Race Series Conrod Bearings feature 3/4 grooving, which optimises oil supply to the main bearings. It's crucial to maintain proper oil levels and viscosity to ensure adequate lubrication, especially under high-stress conditions.
What should I consider when installing these bearings?
When installing ACL Race Series Conrod Bearings, ensure that the bearing surfaces are clean and free of debris. It's also important to check the crush and fitment to confirm they are seated correctly in the conrod and cap.
Can I use these bearings in a street application?
While ACL Race Series Conrod Bearings are primarily designed for racing and high-performance applications, they can be used in street engines if the engine is subjected to higher RPMs or stress. However, consider your overall engine build and intended use to ensure reliability.
