This is very exciting news. What question burns in my mind was sort of asked/talked about here, so I'll throw it out and wait for the experts to speak on it.

Seeing as how Nissan took the VQ35 and increased the displacement to 3.7L and dropped in newer pistons, rods and some other internals. THEN threw on two turbochargers.. Could this mean us low guys with the maxima's VQ35de take the same route and maybe, possibly throw on one turbo?

I'm not asking or thinking about huge numbers, just something a little extra for all those ricer hondas out there.

 

you could always do that, the 3.5 has always been a strong engine, and with the right tuning you can put out 600whp on stock internals, in fact, meximax is making 426 on stock internals.

 

I don't know about 600whp, thats a pretty high number. I would think somewhere around the 500whp on a very very good tune. Thats probably as good as its gonna get on the stock motor and something that not many people especially maxima guys have been able to acheive. There are however some 350z guys pushing around 500whp terriorty on stock motor but having twins tho.
For my setup, stock rod/pistons with ARP rod bolt, studs, HG and valves springs... I plan only to be in the 460-475whp range on race gas/track setup, daily I want to keep it around 375whp to 400whp. Even that is a lot to handle as a DD.

 

Can we keep it on topic?

 

Negatory .. awaiting more info also...

 

The actual fitment to me is the crucial part along with the benefits. After further review of the HR motor PDF, there's allot about the HR motor that were going to have to keep in mind that adds up to why the HR is a whole step ahead of the DE (NA & FI) wise. Such as hydrogen free DLC lifters, height of the block deck and rods are lengthened a redesigned ladder frame, so on and so on will make just getting your hands on the complete motor itself much less of a headache. But their are also many various combinations we may also use to equal or better the performance of the HR. So SR20 keep the technical data's coming. I'm going to be a little more patient this time with my complete 05' DE motor for further data.

 

So do you guys think this new VQ37HR can be added the list with such engines as the RB26DETT?

 

It was already on the list before the 37 or the HR came along. Its now the president of the club.

 

And OT it goes...sigh

 

Ok, so what is the status of the fitment nismology? Got any updates, let's steer this back on topic.

 

I'm interested to hear what SR20DEN says about them, especially weight vs. DE pistons.

 

Yeah we need actual weight differences.

 

The difference in weight is not nearly as important as the reduction in friction and resulting compression ratio (yet to be determined) IMO. We're talking a handful of grams at the most since these are still cast.

 

that's true, less friction would be more important wouldn't it for sustaining longer, high RPM speeds? Which is why I'm sure most of us are interested in using these pistons (I am at least).

 

How long is the coating expected to stay on the skirt? I guess its designed to be there through the life of the motor but is that really going to be the case?

 

Piston heads that weigh less is also of importance since there's less mass to move up and down. And to that end, less friction created can also help with power numbers.

What I would like to know, is how reliable are these internals going to be. I am positive that Nissan threw insane amounts of money into building up the VQ35, but I'd like to see real world test data.

 

Theoretically, yes. Practically, i doubt you'd see any difference by virtue of the weight decrease alone.
