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 compression ratio for the MX2066C piston kit?
The MX2066C piston kit has a compression ratio of 14.0:1, which is designed for high-performance applications. Ensure that your engine is set up to handle this compression ratio with appropriate fuel quality and tuning.
What material is the MX2066C piston made from?
The MX2066C piston is forged from high strength 2618 alloy, which provides excellent durability and performance under high-stress conditions typical in racing and performance applications.
What should I consider for piston to cylinder clearance with the MX2066C?
Piston to cylinder clearance should be set according to the supplied instructions. This is crucial for ensuring proper operation and longevity of the piston, especially at high RPMs and under load.
Does the MX2066C piston kit include everything needed for installation?
Yes, the MX2066C piston kit comes complete with two pistons, ring sets, wrist pins, and clips, providing all the essential components for installation.
What are the balancing specifications for the MX2066C pistons?
The MX2066C pistons are balanced to +/- 1 gram, which helps ensure smooth operation and reduces vibrations in high-performance applications.
