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 4B11T engine?
The ACL Race Series Main Bearings for the Mitsubishi 4B11T feature a high strength overlay plate with reduced thickness for improved performance, hardened steel backs for robust support, and increased crush to ensure a secure fit. They also incorporate 3/4 grooving for optimum oil supply and consistent wall tolerances for precision and reliability.
Do I need to modify my engine block to fit these main bearings?
While the ACL Race Series Main Bearings are designed for the 4B11T engine, it's essential to check for proper fitment. Depending on your engine's machining and clearances, you may need to ensure the main bore is within OEM specifications and that the bearings are properly seated.
What RPM range are these main bearings suitable for?
These main bearings are engineered to withstand higher RPM conditions, making them suitable for performance applications. However, the actual reliability at high RPM will depend on proper installation, machining, and overall engine tuning.
What should I consider regarding oil clearance when using these main bearings?
It's crucial to set the correct oil clearance when installing the ACL Race Series Main Bearings. This will depend on your engine's specific application and intended use. Always refer to the manufacturer's specifications and consider the type of oil you will be using, as this can affect performance.
Are these main bearings compatible with aftermarket crankshafts?
The ACL Race Series Main Bearings are designed to fit the OEM specifications of the 4B11T engine. If you are using an aftermarket crankshaft, ensure that it maintains the same dimensions and tolerances as the OEM unit to guarantee compatibility.
