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 EJ engine?
ACL Race Series Conrod Bearings are designed for high-performance applications, offering enhanced durability and reliability under higher RPM conditions. The high strength overlay plate and hardened steel backs provide robust support, while increased crush ensures a secure fit, making them ideal for racing and performance builds.
Do I need to modify my engine for these conrod bearings?
While the ACL Race Series Conrod Bearings are designed for a direct fit in EJ16/18/20/20T/22/25 SOHC engines, it's important to check for proper clearances and ensure that your conrod journals are within OEM specifications. Some builders may choose to hone the big-end for optimal fitment.
What is the recommended installation procedure for these bearings?
When installing ACL Race Series Conrod Bearings, ensure that the conrod and crankshaft surfaces are clean and free of debris. Apply a suitable assembly lubricant to the bearing surfaces before installation. It's also advisable to check the bearing clearance with a micrometer and adjust as necessary to meet your performance goals.
Can these bearings handle boosted applications?
Yes, ACL Race Series Conrod Bearings are suitable for boosted applications, provided that the engine is properly tuned and clearances are set correctly. However, the overall reliability will depend on factors such as boost levels, fuel quality, and engine RPM.
What type of oil should I use with these conrod bearings?
Using a high-quality engine oil that meets the specifications for your EJ engine is crucial. Synthetic oils are often recommended for high-performance applications due to their superior lubrication properties and ability to withstand higher temperatures, which is beneficial for the longevity of the ACL Race Series Conrod Bearings.
