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 features of the ACL Race Series Main Bearings for the Lotus/Ford 1500-1600cc engines?
The ACL Race Series Main Bearings (5M2152H) feature a high strength overlay plate with reduced thickness for improved performance, hardened steel backs for added durability, and increased crush to eliminate flash plating for a secure fit. They also include 3/4 grooving for optimal oil supply and consistent wall tolerances for reliable performance.
Do I need to modify my engine block for these main bearings?
While the ACL Race Series Main Bearings are designed to fit Lotus/Ford 1500-1600cc engines, it is essential to check the main bore sizes and ensure proper clearances. Depending on your engine's condition and previous machining, some fitting or honing may be required for optimal performance.
What type of oil should I use with these main bearings?
For the best performance with ACL Race Series Main Bearings, use high-quality synthetic or racing oils that provide excellent lubrication and heat resistance. Ensure the oil meets the specifications required for your engine's operating conditions, especially if you plan on running at higher RPMs.
Are these main bearings suitable for street use?
While the ACL Race Series Main Bearings are designed for high-performance and racing applications, they can be used in street engines if the engine is built for higher RPMs and loads. However, if your engine operates primarily under normal conditions, consider using standard bearings for longevity.
What is the recommended installation procedure for these main bearings?
When installing the ACL Race Series Main Bearings, ensure the bearing surfaces are clean and free of debris. Apply a thin layer of engine oil to the bearing surfaces before installation. Follow the manufacturer's torque specifications for main caps and ensure proper alignment to avoid bearing damage.
