False.

Independent testing and comparisons have been done between my 2006 rev-up and a few friends' 287. The rev-up and 287 are dead even until 4th gear, that is when the rev-up starts crawling away.

 

I just odered the M-REV v2 with a 5/16 copper spacer and copper TB heater. Hope this helps my baby with a few more ponies. CAI, Headers, HFC, cat back, & pulleys will be next paycheck. I'm just buying time 'til the GT-R is available and the bugs are worked out of it.

 

So true, so true. The HR isn't proven yet. Too new. Need to wait & see how it shakes out.

 

That's what I've read too. Based on that dyno sheet posted by the folks at motordyne, the HR pulls pretty well from mid to topend, a lot more than the posted HP.


There are so many variables in your independent test that it proves very little for you to anounce False. Things such as driver's weight, modification each car has, how much gas (weight), how quick the driver can shift, etc., can make one car faster than the other. The best test is one done on a dyno, where it actually shows on paper at what RPM each engine produces the most horsepower/torque. The dyno below is from a rev-up 6speed vs a 287 auto (note that it's an auto 287hp; the 6mt would show better torque). Based soley on the dyno sheet, the '06 lags low-end grunt but makes up at the top end, when compared to the older VQ, as I've said before.

Have you ever driven your friend's 287hp Z? Assuming it's a stock 6-speed, put it in 2nd gear at 2K RPM and step on the gas all the way untill redline. Now do that with your rev-up '06 and tell me both feel the same at low rev. They are not the same - the 287hp engine will pull, while the 300hp rev-up will have a slight lag and you will hear pinging noise. After 5k RPM or so, the rev-up starts to pull, while the 287hp engine feels like it's loosing steam. I've driven both -- a brand new, stock '06 and my stock 287hp Z -- so I know how they respond.

 

I think with those mods you're planning to have, I think your Z would be as fast as the stock '07 with the HR, so yeah, it would make no sense to upgrade, unless you're planning to mod the HR in the same manner. I've said it before, if you have the 287hp engine, the new '07 is really worth the test drive. However, if you've got the rev-up, it's better to wait for the next best thing from Nissan, as the cost to replace a one-year-old car is not worth the few HP & torque gained from the VQ-HR. That HR is so fun to rev though

 

If you want some revving fun, get a RX-8.

 

Hey guys, after taking a 5 minute inspection about a month ago at the HR sitting at Nissan of Fort Pierce (PSL, FL), I broke out into a cold sweat and almost threw up !! I had just bought an 03 DE touring 3 months before and had about $6000 in mods into it already. I was about to install a UTEC, on my way to hit 270 whp on a mustang dyno... I immediately pulled the plug on the project, put it on autotrader, sold it for $25,000, and picked up a PPW base the next day !! Okay, it's been 2 weeks now since I had it...I blow past all my 03 to 06 350Z boys from 80 to 160, leaving them real bad, maybe 20 cars or so per pull, I even stomped an 06 WRX STI with Intake/exhaust from 80 to 160, and beat a CBR600 Honda bike from a roll in 3rd...Did I make the right decision, IT WAS THE ONLY DECISION !! I am a motor guy, when I see potential in a motor I go for it..I have an 800 rwhp Supra in my garage that I have not driven since my HR came home www.cardomain.com/id/yb2fast . All I can say at this point is, I can only imagine what this motor can do with breathing mods and FI in the future !! I think a NEW 2JZGTE has hit the market with a NISSAN BADGE on it !! (lol)..BTW, I also hit 156 mph in 5th without hitting the rev limiter !! VIVA LA VQ35HR !!

WTF dude...how do you get up to 160 on public roads? Did you rent out an airstrip or something?

Be safe bro.

 

How would u compare a stock HR to a modded 287 motor? I am talking intake,spacer,headers,tp's,exhaust,pulleys,tune. I am asking because I wanna know is it worth trading up for or waiting for the inevitable 3.7L. Also u said it felt softer... softer how like the suspension/ride quality or what?

 

The initial write-up is dead on. The 07 is a much improved version over my 03. I picked mine up on Monday and it is quicker. The power really kicks in at 4000 rpm. It's almost like there was a turbo. I especially like the higher rev limit. Instead of 58 in 2nd you can get to 70-71. I plan to campaign in autocross this year and make life miserable for the RX-8s for a change. I let a friend with an RX-8 drive it today and he is of the same opinion.

 

Wow 71 in 2nd!!! Amazing. Wonder what the unrestricted top speed will be with the higher redline.

 

(LOL), When you own an 800RWHP Supra, 160 mph is childs play !!

 

I cant wait for my licensr plate to come!!

VQHR FTW

 

W.T.F

 

But when you drive a car with only 300 hp it takes forever to get there and is therefor NOT childsplay. Not to mention the inadequacies of other drivers.

And there is no way the HR could replace the 2JZ - those motors are I6's with iron blocks capable of high boost in stock form (thanks to stock turbos meaning forged parts galore).

The HR is a V6 meaning the crank bearings are already a bit stressed, and the engine harmonics would not be very suited for a 20 psi boost level - not while being durable at least. The new 2JZ is going to be the BMW S54 - look at hpfreaks M3 if you don't believe me.

 

I just wish there was a stock 287 and a HR that would do some vid runs with me highway wise all te way to the damn rev limiter to see what these engines are about. Damn florida for not having anything like this. lol. But hey theres always the independent highway test lol.

If the 287 hp has all those mods you listed, especially with test pipes, it would probably be faster than a stock HR - I don't know as a fact, because I haven't driven one with all those mods, but I wouldn’t be surprised at that outcome.

The benefit the HR has over the previous VQ's lies in its potential - I truly feel that with the same types of mods you listed, especially test pipes, it will outperform both the 287hp and rev-up engines with identical upgrades. And the fact that it comes with equal-length headers means one less upgrade you have to pay for. I saw those headers at the L.A auto show, and they are a work of art. In stock form, this HR has the pedigreed of a true sports car engine: high-rev limit, dual intake manifolds, equal-length headers. With a few efficient mods to it, it would shine really bright, I think much brighter than the engines it replaces.


The '07 gave the feeling of being tuned softer than my '04 because of a few changes: steering is much lighter at parking-speed due to variable-speed power steering, the clutch is way softer -- too soft for a sports car -- and the more luxurious interior, which seem a little more quiet. The changes isn't a bad thing; it just changed the character of the Z from raw, loud, and fast into more luxurious, simi-loud, but faster -- thanks to the new engine. Without that HR, I wouldn't even think about a test drive.

As far as the new '07 being worth the trade or not, I think you should take a test drive to see how you like the new upgrades, then form your decisions. The new engine deserves a test drive, and make sure you take it to reline and explore all its potential.

yup, I second that. Would be sweet to see those two go head-to-head

 

That's awesome. Is't the engine fun to drive or what? I love that rev limit compared to my '04's. When I drove the HR and cruising at 4k RPM, I couldn't help but be amazed at how much more I can rev before I needed to shift - nearly 8k RPM. In an S2000, I would expect high-reving, but not in a Z. And unlike some high-reving engines, which are tuned for top-end and not low-end, the HR actually pulls nicely at low RPM too. Nissan got it right on tuning this engine. Now all they need is to add even more HP lol

 

I just test drove one today. It was pretty nice overall although the clutch did feel a little weird. And i only got a chance to get on it once and killed the tires in first and then got a lil side ways going into second. The cold pavement didn't let me have any fun. Although i did take it up to 7500! But i didn't get a real feel for the new engine. So i'll have to test drive one again when it gets warmer.
And i do believe i had the hottest sales chick ever!
