Seeking to see if parts from the G37 and Frontier (V-6) engines share same parts. I can see part numbers for the on-line Nissan parts but for some reason, the Infiniti sites don't publish part numbers.

I'm looking at timing chains and guides as we own one of each of these vehicles.

Attached is part break-out for the G37 and items 17 and 18. Some numbers from a Nissan site are 13091-D40001, 13028-D40006 and 13085-D40002.

 

May I ask what it is you are trying to accomplish?

 

10 or 15 years down the road when engines are replaced with different units, keeping track of which parts fit and which don't is a good idea. It's simply more useful information to keep in the database. Unless the OP has something else going on
