has anyone seen a VR block with 370 heads yet?
heard this is possible and zfever was working on one but havent seen any info on it, vr38 block with 370z heads into a 350z

Sounds like too much work....Stick to your LS swap hahah...Hows that monster clutch holding up?

why bother changing the heads?

I've read that z fever made g37 heads fit on the vr38 block. But then the issue of what transmission will you use comes up.

from what i was told the gtr heads wont work in the swap.

I don't understand why. Even if there was an issue with the VQ ECU controlling the VR motor, couldn't they swap the ECU too or run a full stand alone EMS?:dunno:

My thought exactly. Maybe I am missing something.

Its easier and cheaper to fine full stand alone for the HR and VHR heads than the VR heads.
For me, I would rather use the HR heads. Over 300cfm stock FTW |

From what I understand there are no standalones that can control VR/VHR heads properly (due to VVEL). I'm guessing Zfever swapped to HR heads because of this.

OK, but again that begs the question of why don't they swap in a VR ECU as well.:dunno:

A more plausible route might be VHR heads and a VHR ECU. Or HR heads and a stock ECU (as the customer chose). Hell it could be financial reasons on behalf of the customer, I doubt a VR swap is cheap all by itself. |

it is not different than putting the original haltech (stock ecu + piggyback) in a VQ35de or swapping in the LS1 (piggyback stock ecu with gm ecu)
the GTR ecu only needs to control engine functions. The tach might not work, but its no different than an LS swap. Better yet, run the GTR motor on a Proefi or Syvecs and dont even worry about the gtr ecu. So i still dont know why they'd mess with running 370z heads when the full GTR package is way superior.

But the question is would it be worth the added cost? How much better to VR heads flow than HR heads? Would the stock rods give out before the heads started limited flow?
Wiring in the GTR ECU especially if it's never been done before would add significant cost to the build. The customer's wallet ultimately decides what happens. |

i dont think the hr heads work on them, theres a little difference between the hr and the vhr heads height wise

if it's vhr heads going onto the vr block I'd be even less worried about flow issues and more welcome to the simplicity of not hacking in a gtr ecu.
