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 Nissan TD42 ACL Race Series Main Bearings?
The Nissan TD42 ACL Race Series Main Bearings feature a high strength overlay plate with reduced thickness for enhanced performance, hardened steel backs for added strength, increased crush for improved reliability, and 3/4 grooving for optimal oil supply. They also maintain consistent wall tolerances for a precision fit and have oversize chamfers where applicable.
Do I need to modify my engine for these main bearings?
While the ACL Race Series Main Bearings are designed for a direct fit in the Nissan TD42, it's essential to check the main journal sizes and ensure proper clearances. Depending on your engine's condition and previous machining, you may need to perform line boring or other adjustments to achieve the correct fit.
What RPM range are these main bearings suitable for?
The ACL Race Series Main Bearings are engineered to withstand higher RPM conditions, making them suitable for performance applications. However, the actual reliability at elevated RPMs will depend on proper installation, clearances, and overall engine tuning.
How do I ensure proper lubrication with these main bearings?
To ensure optimal lubrication with the ACL Race Series Main Bearings, it's crucial to maintain a clean oil system and use high-quality oil that meets the engine's specifications. The 3/4 grooving design helps facilitate oil flow, but proper oil pressure and volume are essential for performance and longevity.
Can these main bearings be used in a standard TD42 application?
Yes, while the ACL Race Series Main Bearings are designed for performance applications, they can also be used in standard TD42 setups. However, if you're not pushing the engine to higher RPMs, standard bearings may suffice, depending on your specific performance goals.
