Default VQ37HR vs VQ37VHR

I am looking into upgrading my 2008 350z to a 370z. I am wondering what the benefits of the VHR engine are compared to the HR. I know the HR engines are great and Iíve read some forums on here saying that stock, they can take forced induction and run with it for quite some time. Iím wanting to get something I really like before modding it in any way. So I am just looking for the best option out of all the Z cars and which one can take the most, without putting in the effort and funds to bore out the engine. What should I get and why should I get it? What are the benefits of that one up against mine? Thanks!

It sounds like you're asking about which is the more suitable ENGINE to hot rod but later, it the sounds like you're asking about which CAR (bold, highlighted).

If you're asking about entire platform, my thoughts (take as you wish):
https://my350z.com/forum/buying-leas...l#post10962728

If you're only asking about the engine, I'll cut to the chase (IMO): NOT worth it given the electronics (ECU, harness, etc) and other issues you'll run into swapping it. Search the archives of HR engine related posts (9 years worth!) to see why.

Z'matter of fact, that will actually lend more to my pro-Z34 argument: more turbo and supercharger applications for the newer chassis with VHR engine THAN Z33 HR.

If I were to buy a Z today, it'd be the 370z Nismo everything is already factory maxed in comparison to other model Zs. From building Hondas in my youth with 8-9k redline, seems silly for Nissan to call 7.5k "very high rev" still not used to it, I digress.
