What does 'standard size' mean for these bearings?

Standard size bearings are meant to be used with a crankshaft that is at its original factory diameter. If your crankshaft has been machined undersize due to wear or reconditioning, you would need a different size bearing set.

Are these bearings suitable for a turbocharged engine?

Yes, these are considered high-performance bearings and are designed to handle the increased stresses found in modified and turbocharged applications.

Do I need to order these bearings individually or as a set?

This product is a complete set of main bearings for your engine. You will receive all the necessary bearings to replace the main bearings on your 4G63 or 4G64 6-bolt engine.
