Slow down everyone... This motor also goes into the Altima and will find its way to replace all the VQ35DE's. What makes everyone so sure the internals are made for FI?

 

LOL your trippin. Wait and see then you can apologize for you dumb as s comments.

 

I guess we'll find out sooner or later. I believe Sharif is going to toy around with one when his friend gets one.

I think turbotim (SFR I think) plans on boosting one asap once they have everything figured out.

 

You actually believe the HR is going to make 100whp more than the DE at 10psi?!! You can't be serious.

 

Maybe 12lbs. The downpipes and exhaust may have to be modified but I think it can be done. The heads and cams are like highly modified ones we've been putting on the DE to get a lot more power. It's just what I think. I have no clue I'm making an asumption. We'll have to wait and see.

 

And what about the deck design ????? is the same open deck that the vq35de have.........

 

this HR thing is done by REANU ppl. what i know that those guys joine nissan or somthing like that.
so its not a nissan plans.

and for the power what its making. its onley cuz of the twin TB and that Equal length Headers.

if that COSWORTH plenum came out, and with some big TB. the DE will performe better.

That article should be required reading for any VQ enthusiast.

 

Tech data for 2007 VQ35s are posted here.

The VQ35HR has the SAME 144.2mm long (center to center) rods as all other VQ35DEs. They do however have larger journals.
And the 2007 Altima VQ35DE is not the same engine even though it does share some of its parts. Such as the SMALLER valves.

 

Wrong...read the article above about the rods and then you'll change your mind.

 

Hey why is everyone arguing this. Their is not even one out yet or not that i know of. Who knows what this motor can handle atleast the shotblock has been improved and the internals got a little biffier. Head wise dont know better flow now who know how they will react to boost remember now it .1 CR higher nothing big but can make things abit different. We all hope it comes out stronger then the last VQ because it really sucked. Personally i dont see nissan designing engines for turbo or engine for the aftermarket world. I think they just want to make great OEm engines that perform the way the were built.

Now the skyline is a way different game. Im pretty possitive that this engine will surpass the RB and even maybe the 2jz but this if nissan puts its head into this engine Atleast from the skyline we should have real nice solid platform and wont have to build until 700hp plus that would be nice.

To me if the VQ was designed around the turbo specs and iron block i dont think any other import motor should come even near it. I think we should just talk about it but dont make facts on engine that hasent even come out yet.

 

Actually, the article is wrong. He got his info from the 2007 G35 Factory Service manual. And in case anyone is wondering, FSM > *.

 

I READ the PUBLISHED data by Nissan. The 2007 G35 Sedan service manual AND the 2007 350Z service manual BOTH show a 144.2mm rod.

 

What are you talking about? The 2007 G35's are out and they have the HR motor. And the regular VQ35 sucked? According to what criteria? Just cus it can't handle 600 WHP w/out building doesn't mean it sucked. Simpletons, i tell you.......
This post proves you have no clue. You actually think nissan should/would revert back to an iron block?? Furthermore, not only is the engine already being used in cars that are CURRENTLY on the road, SR20DEN is quoting facts from the Factory service manual. Yes, FACTS.

 

People shouldnt try to argue something that they have no clue about. I looked over the 07 Z FSM yesterday with a nissan tech while getting my truck serviced. The article posted above pretty much explains the key differences but for you lazy folk. Read below.

The motor has MANY differences then the DE, lets start here:

Crank: Totally reworked. This is built stronger then the VG30 and RB26DET. The VG30 and RB26 had very similiar crank designs and need to be rebuilt with high HP applications. The HR will NOT need to be.

Block: Deck height has been raised. Pretty good chance this will help to decrease the chance of head lift @ high boost.

Rods: Much better design then the DE. Power metal forged and about a 1/4 more beef.


500-600WHP anyone?

Pistons: Picture explains better then I can

 

like others have said, we won't know until someone slaps a turbo on it, but my question is...will the motor be a direct swap into 03-06?

 

Who is this directed toward? SR20 wasn't saying the rods are the same, but that they're the same length. That article has some holes in it BTW.

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.

 

Also, to whoever would rather say "stop speculating about this motor...it hasn't come out yet blah blah" instead of actually contributing to the INTELLIGENT discussion of this motor please don't bother posting.

 

I don't think that everyone who has posted after me is specifically trying to argue with me. So don't blow a fuse man.

 

I actually thought it was originally directed at me or you since we seem to be the only people that don't think the article posted on NPM is infallible.
