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 is the recommended bore clearance for the M2015 piston kit?
For the M2015 piston kit, it is crucial to set the bore clearance according to the manufacturer's specifications. Typically, a clearance of 0.0015" to 0.0025" is suitable for performance applications, but always verify with the specific engine build requirements.
What compression ratio does the M2015 piston kit provide?
The M2015 piston kit offers a compression ratio of 12.5:1. This higher compression can enhance performance, but ensure that your engine is properly tuned and that you are using high-quality fuel to prevent knocking.
What type of material is used for the M2015 pistons?
The M2015 pistons are forged from high strength 2618 alloy, which is known for its durability and ability to withstand high temperatures and pressures, making it suitable for performance applications.
Does the M2015 piston kit come with everything needed for installation?
Yes, the M2015 piston kit includes two pistons, ring sets, wrist pins, and clips, providing a complete solution for your rebuild. Ensure you follow the installation instructions carefully for optimal performance.
What is the significance of the double forced pin oilers in the M2015 pistons?
The double forced pin oilers in the M2015 pistons help ensure adequate lubrication to the wrist pin, reducing wear and improving reliability under high-performance conditions. This feature is particularly beneficial in high RPM applications.
