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 Honda A18/B18 engine?
ACL Race Series Conrod Bearings are designed to withstand higher RPMs, making them suitable for racing and high-performance applications. Their high strength overlay plate and hardened steel backs provide durability and longevity, ensuring your engine runs smoothly even under extreme conditions.
Do I need to modify my engine for these bearings to fit properly?
While these bearings are designed for a precise fit in Honda A18/B18 engines, it is essential to check for proper clearances and tolerances during installation. Depending on your engine's condition and previous machining, you may need to ensure that the conrod and crankshaft journals are within OEM specifications.
How do the increased crush and tight wall tolerances of these bearings affect performance?
The increased crush helps eliminate flash plating, providing a more secure fit within the conrod. Tight wall tolerances ensure consistent oil clearance, which is crucial for maintaining proper lubrication and reducing wear, ultimately enhancing engine performance and reliability.
What oil should I use with ACL Race Series Conrod Bearings?
Using a high-quality synthetic or racing oil is recommended for optimal performance with ACL Race Series Conrod Bearings. Ensure that the oil meets the required viscosity and performance specifications for your Honda A18/B18 engine, especially under high RPM conditions.
