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 Mitsubishi 6G72?
The ACL Race Series Main Bearings for the Mitsubishi 6G72 feature a high strength overlay plate with reduced thickness for improved performance, hardened steel backs for durability, increased crush to eliminate flash plating, and 3/4 grooving for optimum oil supply. These features ensure precision and reliability under high RPM conditions.
Do I need to perform any machining before installing the ACL Race Series Main Bearings?
Yes, it is recommended to check the main journal sizes and ensure proper clearances. Depending on your engine's condition, you may need to perform line boring or honing to achieve the correct fit and tolerances for optimal performance.
What is the recommended clearance for the ACL Race Series Main Bearings in a 6G72 engine?
Clearance specifications can vary based on the engine's intended use and build. Generally, a clearance of 0.0015" to 0.0025" is common for performance applications, but it is essential to consult with your engine builder for specific requirements based on your setup.
Are these bearings suitable for turbocharged applications?
Yes, the ACL Race Series Main Bearings are designed to handle the increased stresses associated with turbocharged applications. However, proper installation and tuning are crucial to ensure reliability and performance.
How do I ensure proper oil supply when using these main bearings?
To ensure proper oil supply, make sure the engine is adequately prepped and that the oil passages are clean and unobstructed. The 3/4 grooving design of these bearings aids in oil distribution, but maintaining proper oil pressure and using quality oil are also critical for performance.
