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 Cosworth engine?
ACL Race Series Main Bearings are designed for high-performance applications, providing superior durability and reliability under increased RPM conditions. The high strength overlay plate and hardened steel backs ensure that these bearings can withstand the stresses of racing and high-output engines.
Do I need to modify my engine block to fit the 5M2167H main bearings?
Typically, the 5M2167H main bearings are designed to fit standard specifications for the Ford 1293/1593/1993cc Cosworth engines. However, it's crucial to check the block for any irregularities and ensure proper machining for optimal fitment and clearance.
What is the significance of the 3/4 grooving in these main bearings?
The 3/4 grooving in the ACL Race Series Main Bearings enhances oil supply to the bearings, ensuring better lubrication and cooling under high-load conditions. This design feature helps maintain consistent performance and reduces the risk of bearing failure.
How should I prepare the engine block before installing the ACL Race Series Main Bearings?
Before installation, ensure that the engine block is cleaned thoroughly and that the main bearing journals are machined to the correct specifications. It's also advisable to check the bearing clearances with a micrometer to ensure they meet the recommended tolerances for your specific application.
What type of oil should I use with these main bearings?
Using a high-quality synthetic or semi-synthetic oil is recommended for optimal performance and protection of the ACL Race Series Main Bearings. Ensure that the oil has the appropriate viscosity for your engine's operating conditions, especially under high RPM and load scenarios.
