Question 1

What does NA/VC mean?

Accepted Answer

NA stands for Naturally Aspirated, meaning the engine doesn't have a turbocharger or supercharger. VC likely refers to a specific engine variant or trim level within the Mazda lineup during those years. Always double-check your engine specs.

Question 2

How do I know if these bearings are the correct size for my engine?

Accepted Answer

This bearing set is 0.75mm undersize. This means the crankshaft journals must be machined to match this undersize. Always consult a professional machinist during engine rebuilds.

Question 3

What other parts should I replace when replacing the connecting rod bearings?

Accepted Answer

When replacing your connecting rod bearings, it's always a good idea to inspect and/or replace the connecting rod bolts. Also inspect the crankshaft journals for wear and have them machined if necessary.
