Dyno vq35HR Vs. DE
Like everything learned over the past few years, nobody really knows what the stock VQ35HR is going to be capable of until shops start playing with them... 'Til then, it's all up for debate.
We know that even a stock DE can push 500whp (see GTM's new success story on this), so I don't doubt that we'll see great numbers come out for these engines. The question is whether or not it's going to hold up well past that mark given proper tuning and FI application.
No offense to anyone here, but I think it's too early in the game to be stating any facts.

And i don't think the increased deck height has anything to do with "head lift".
Since the HR rods are the exact same length and the stroke is the same, the logical conclusion is that the compression height on the pistons was increased to promote stability in the bore. This increased piston length is probably to compensate for the reduced skirt area of the new piston design.

The combustion chamber will also be more efficient since they increased the size with could potentially help with any kind of lift.

(No offense bigbri
) Maybe 12-15PSI.

In regards to rod length - the new HR's DO have longer rods. FSM > all, but apparently in this case Nissan dropped the ball on proofing the manuals. The rod is 8mm longer, same as the block height increase of 8mm.
I just had an HR rod double checked with a caliper, and it is 152.2 center to center. 8mm longer than the 144.2 VQ3DE rods.
Nissan really got their act together on this motor by changing to a two piece block! In stock form they may just make marginally more power, but the potential for 1000+hp was increased greatly.

Good. I said in my other thread on maxima.org that the ESM data might be wrong. Now we know for sure.

Also, VQ35DE heads bolt on / work with the VQ35HR.

Work? I doubt that. The DE heads will fit behind the HR cover, but I would almost guarantee the HR heads wont fit behind the DE cover - and the HR cover wont fit the DE.
