New guy here and im.trying to learn about the venerable v6 VQ35de.

I know it's in.lots of Nissan models, is the VQ35de from say an Altima or a 350Z THE SAME motor or are there manifold or cam or exhaust variations accross the lines?

I've heard about the cast oil pump gear unaliving itself in the 7K zone, is there anything else bad that happens up there? Are the stock valve springs up to the task?? They seem super wimpy...

The dual path intake manifold is clever, who's modded it? What did ya do, deltw VIAS? Any gains?

Thx

AJ
