I've seen a lot of info back and forth over these two variations of the VQ35DE. Is there a clear advantage of one over the other? Just curious because I've been looking at 03's and 04's and I like 06's and up but only cuz of intelli-key. Just curious. Thanks in advance.

 

to each his own, before my 06 rev up went FI, i raced non rev ups a lot just as modified as mine and id win by a car every time

 

i hear the rev-up have like 10 odd more HP but it burns excessive oil.

 

I have a Rev-Up and I don't think there is one IOTA of difference between the two. One has more TQ, and one has more HP. The Rev-Up has a higher red line, but I don't think there is any useable HP/TQ there (until I put on the MREV2 & 5/16" spacer!). I shift at 65-6800rpm. It all works out in the end.

 

not much diff. in my opinion

 

no difference acceleration wise. It has been proven.

 

what is the redline diff?

 

Well, I know the redline on non rev-ups is like 6800 or something. I think revs are 7300 or 7500. Most cars don't make power up to the redline anyway, so if that is the significant difference, then I'd tend to agree that other than fancy verbage, there is none. But, I'm not expert by any means. (hence the post).

 

6700 none rev-up, 7200 rev-up

No significant dif in performance.

Besides, either can be modified to beat the other and it doesn’t take more for one than the other.

 

yeah..its just the "new" model engine.

 

Having owned G's with HR and a non-HR engines, I must say that the non-HR is a better match for the G in real world everyday driving. The G 35 is not a light weight sports car, high winding lower torque engines are not the answer. They need torque. The more the better.

Granted the non-HR only has 10ftlbs more torque than the HR, but it delivers a more useful power band than the HR.

 

lol.

 

Revups don't have as much of a powerdrop after peak power like non-revups do. Any tuner will concur with that. The revup is the better engine, but the differences are very subtle.

 

Sorry but this is nothing close to the truth. The VQ35HR and VQ37VHR are superior engines compared to the DE.

The VQ35DE makes great torque, but don't have that top-end like the HR/VHR. And its not as if our VQ35DE's are torque monsters to begin with.

 

So, between the two, is there a REAL WORLD difference? Whether it be performance, reliability, or anything in between, do the motors hold up. I ask because my ONLY experience is with the VQ35DE. It held up fine under what I put it through and I summise that any advancement would be okay; especially given that the next car will not be thrashed upon as my Z was.

I also may want to boost it somewhere down the line. I remember when the Z came out (and maybe two years into it) any type of boosting really required you to reinforce the bottom end whether you planned on making a lot of power or not. APS's TT kit was the only real bolt on kit on the market at the time and that only made about 330-350rwhp at best. I know there's a lot more out there now, and I may not even do all that, but I guess I want to know what I'm in for if I go with an 05+
