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 main benefits of using ACL Race Series Main Bearings in my TD25 or TD27 engine?
ACL Race Series Main Bearings are designed for high-performance applications, offering enhanced durability and reliability under increased RPM conditions. The high strength overlay plate and hardened steel backs provide added strength, while the 3/4 grooving ensures optimal oil supply, making them suitable for racing and high-stress environments.
Do I need to modify my engine block to fit these main bearings?
Typically, these main bearings are designed to fit the standard specifications of the TD25 and TD27 engines. However, it's essential to check for any machining requirements or tolerances specific to your engine build, as variations can occur.
What should I consider regarding installation and clearances when using these main bearings?
When installing ACL Race Series Main Bearings, ensure that you achieve the correct clearance as specified by the engine builder. Consistent wall tolerances are designed for a tight fit, but proper measuring and fitting are crucial to avoid issues like oil starvation or bearing failure.
Are these main bearings suitable for boosted applications?
Yes, ACL Race Series Main Bearings are engineered to withstand the demands of boosted applications. However, the overall reliability and performance will depend on proper engine assembly, tuning, and oil quality. Always ensure that your engine is built to handle the additional stress of forced induction.
