Question 1

What does '0.25 oversized' mean?

Accepted Answer

The bearing is 0.25mm larger in outside diameter than the standard size. This allows for a small amount of material to be removed from the connecting rod bore, creating a perfectly round surface for the bearing to sit. Always plastigage your bearings to ensure proper oil clearance.

Question 2

What if I don't need oversized bearings?

Accepted Answer

If your connecting rods are standard size and in good condition, you should use standard-size bearings. Using oversized bearings in a standard-size rod will result in too-tight oil clearances, which can damage the engine.

Question 3

Are these bearings compatible with aftermarket connecting rods?

Accepted Answer

These bearings are designed to fit standard Nissan SR20DE/DET connecting rods. If you are using aftermarket connecting rods, you will need to verify the bearing size and compatibility with the rod manufacturer.
