In my humble opinion, grab the 03. That's too many miles on an 06. No fear of consumption, either. Its well out of warranty, and you're screwed if it happens to be burning 1.5qts/3k miles or worse. You'll still have PLENTY fun with the 03. If anything, you can upgrade to 06+ tails & headlights as one of your mods. Then nobody will know you're driving an 03-05 edition unless you have stock rims 
good advice...browsing another Z forum (we allowed to link?) about comparing the two engines.. essentially comes down to driver, but the 06 has added weight, wikipedia says its 150lbs. but a user said the 03-05 was underrated anyway
Stock for stock an 03 track will take an 06 track but this can be fixed with weight reduction and Motordyne spacer and M-Rev.
Straight line - 287 hp is better. You need TQ to move the car
Road course - 300 hp rev up is better. It had a wider power and from what I hear it is a more consistant power curve.
Both are a very impressive package.

In a straight line, it's a driver's race, regardless of which engine you have. With that said, I believe the 300hp engine to be better than it's predecessor. The revup motor pulls better up top and the higher redline allows you told maintain a lower gear. The slightly higher redline might not seem like much, but when you're really cooking, it does come in handy.
After having a 2005 Enthusiast for comparison, the 2006 definitely pulls harder in the higher RPMs. I liked the torque of the 2005 model, but it didn't have the "push back in the seat" of the 2006 during heavy acceleration. Not a big difference but some. I definitely think it would be a driver's race.
Increasing the HP resulted in a loss of TQ I dont believe it was the goal to loose tq, its just the methods used to increase power. The red line increase and plenum differences have alot to do with the power and tq diff between the 2 engines. One is not necessarily better than the other its just that when making the TQ HP trade off, the loss of tq is more noticeable than the gain in HP as far as FEELING but in the magazines the performance #s didnt change between engines so its more about feeling than actual speed. Although the TQ will help the 287 pull at first, the HP will help the rev up catch up in time for it to not matter. In the same way that the Motordyne M-Rev will remedy the loss of tq, a Reflash that will, among other things, include an increase of revs to make the red line 7100RPM will help the 287 engine to gain that extra boost acheived by the rev-up motor. So no matter wich engine you have, you can get the same results/feeling as the other and then some with a couple mods. At the same time, you wouldnt put an M-rev on a 287 engine, you cant increase the red line on the rev up engine, so in the end they will still be pretty much the same. Although I preferr the 287
There is no difference. You can argue all you want that one is better than the other, but there really isn't that much of a difference. The only major differences that should be pointed out is the VTC on the exhaust cam, upgraded internals, and higher redline.

Yeah!! They definitely know what they're talking about. Great discussion you're a part of. I really want to do the MREV2 + Spacer mod to make up for some of that loss of tq, and from what I can tell it adds some good HP as well. Should feel as torquey, if not even more torquey than my 03 was.

Yes that's one of the things I was pointing out in my original post. The RevUp does a beautiful job with consistent power, and it does push you back in the seat under heavy acceleration more than the 03-05s do at higher RPMs.

I used to have an 03 before I upgraded to the 06. Loved the power and torque on that motor, very sexy indeed. When I made the switch this summer to the 06, I actually felt a little disappointed with the RevUp. It just didn't have that "umph" the 03 made. 300hp/264lbs compared to 287hp/274lbs really didn't seem like much of a difference to me. But you can definitely feel it.
Its been scorching hot this summer in SoCal, but today was actually very very cool when the sun went down (low 60s). To my absolute shock...... it felt like my motor had a complete overhaul. In the cold, this thing is an absolute monster. It pulled so much harder, and the best thing about this motor that I have noticed is that the RPM's just keep going. I found myself thinking I need to shift, but the RPM's are still at 5,500 and I have until 7 before I need to upshift. Not to mention the freaking noise....... omg. What a monster
. I can't wait until the weather cools off now! Gives me a completely different feeling than my 03 did. The power just kept on goin and goin it was so beautiful. Ugh. Sorry guys, had to just let this wonderful feeling out LOL.
For those who are wondering, my car is not consuming oil. A little over 1/4 of a quart per 3,300 miles. Perfect.
I know that some of you are going to say, all cars perform better in cold weather. Yeah I know that. I'm merely expressing my surprise that the motor indeed has something special about it that the 03 didn't have. That is all

had the 03 for 3 years and have had the 06 for the last 5 years. 06 pulls harder up top. Is more exciting at triple digit speeds. what some of you are feeling bout down low can be remedied with lightening the car also. It DID gain 200 pounds from 03 -06. Something to think about So for the to be any way comparable is something of a marvel in stock form for the engine.
And yea Hr is nasty.
P.s. smooth power bands make some cars feel underwhelming till you realize that anywhere in the powerband you have power so you don't just get that sudden kick in the pants acceleration. You don't notice smooth and hard pulling as easily. Please don't take that sentence in a nasty way.

With my 19's and 245/275 setup, I'm adding even more weight to that 200lbs hahahahahaha. Yeah I can't wait until I do my modifications. I still have yet to see anyone who has taken a non-consuming RevUp motor, and building the hell out of it.
You and I both brother. I love my Rev-up engine. I'm just self conscious cause i know it's getting up in the mileage and sometimes drive a Z06 so I wonder if it pulls as hard as I remember from when I first got it.
Throwing on 275 35F 295 35R this week though. Won't help the situation but Sexiness is gonna go through the roof.

You think you love the revup just wait till you drive a HR I love mine. Floor it in 3rd around 2k rpms and you can feel the power band all the way up to 7200 Rpms. It never misses a beat all the way through 5th and low into 6th.

i have an 06 rev-up bro, and i have the momentum FI kit on it and i have to say, it is an absolute beauty with the powerband pull. Even before the build, i felt the acceleration all throughout the band. It is amazing to me. Ive only driven economy 4 cylinders before the z, and when i got this car, its the most amazing car ive ever owned and had performance wise.

Sorry to bring up an old topic, but it's relevant
I test drove a super clean charcoal gray 2006 Z manual (bone stock).... man did that thing pull all the way to redline. I chirped the tires into 2nd gear when shifting at about 6500. Price is a little high of $16k with 72k miles
About to drive a black 2006 with wheels, CAI, and exhaust later this week. It has 99k miles but is only $14k. These Z's get every penny they're worth around here. This one may be it.
Not used to this power (my car has 100 less torque and hp) so it felt weird pushing the pedal all the way down when going past 4k rpm... kind of like I should let up, haha.

Hopefully some members are still active on here considering this is an old thread. I have been looking at either going with a 2005 or a 2006 350z. There's obviously pros and cons to either engine from the factory. I couldn't find any comparisons of the Rev-Up + MREV2 vs the stock DE (03-05), does anyone have any experiences with this comparison? Thanks!
