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 benefits of using RB25NEO ACL Race Series Main Bearings?
The RB25NEO ACL Race Series Main Bearings are designed to withstand higher RPM conditions, making them ideal for performance applications. They feature a high strength overlay plate for durability, hardened steel backs for robust support, and increased crush to ensure a seamless fit. Additionally, the 3/4 grooving optimises oil supply, which is critical for maintaining engine health under stress.
Do I need to modify my engine block to fit these main bearings?
In most cases, the RB25NEO ACL Race Series Main Bearings should fit without modification, but it's essential to check the specific tolerances of your engine block. Depending on the condition of your block and previous machining, you may need to ensure proper clearance and fitment, especially if the engine has been previously rebuilt or modified.
What is the recommended installation procedure for these main bearings?
When installing the RB25NEO ACL Race Series Main Bearings, ensure that the bearing surfaces are clean and free from debris. Apply a suitable assembly lubricant to the bearings and journal surfaces before installation. It's crucial to follow the manufacturer's specifications for torque settings on the main caps to avoid bearing damage.
What type of oil should I use with these main bearings?
For optimal performance with the RB25NEO ACL Race Series Main Bearings, use a high-quality engine oil that meets the requirements of your engine setup. Synthetic oils are often recommended for their superior lubrication properties, especially in high-performance applications. Always ensure that the oil viscosity is appropriate for your engine's operating conditions.
