hi guys, well last few days i have test driven an 06 and an 07 350z, the thing i would like to know since im not well experienced and really cant notice much difference except hp? if even.. what are some key things that you have felt have changed (drastically) in the 07 compared to the 06. would prefer answers from those that have driven both models. but any input is much appreciated.
thanks.

rev up DE to the standard HR. the HR is a much better platform. I've driven both, the HR is definitely more enjoyable.

there are no 'drastically' different changes outside of the engine, there are some minor differences, but none important enough for me to care about.

MAJOR difference the engine

+1 for the HR id go for the 07

I've driven both. The motor is the main difference. Depending on the price between the two and if you can afford it (or choose to). I would say go with the 07-08's. There are more mods for the 03-06's though. Hr's are slowly catching up.

price difference is roughly 3k from an 06 to the 07, mileage is 7k difference 06 being lower in miles. and like others stated, the engine was the only thing i felt any difference in (though one was leather and other wasnt :P)

from my point im not into street racing at all, speed is nice at starts and i tend to cruise @ 70-80 on my current car, besides the hood on the 07, im not sure if the change would make me go for an 07 rather than an 06 atm. though the engine does seem a bit more sturdy and the HR is cool, im getting an Auto.. so unless i decide to push it to the metal its not like the HR would make much difference.

besides that i have yet to feel any difference in an 07 than the 06.

that doesnt justify actual driving experience, the info is good but not what i was looking for.

If you dont care about mods or getting 300whp n/a then go with the 06'. Save some money. The only reason the 07+ are more desired is because the engine has a better response to bolt on performance mods. I want to get 300whp from my REVUP 06', but I wont get it unless I have a fully built engine. The 07+ on the other hand will make 300whp with just bolt ons and a tune.
So, your decision is based on your hp goals really. And the 06' reliability (oil consumption)

dont believe Autos have the same problem with oil consumption... at least not from what i have read. might go for the 06, since i dont plan on modding it but at the same time i feel i may regret it later for not getting the 07.

The HR is definitely better if you want a stock driver. You may want to weight the options carefully.

I would have to disagree with the "300rwhp go 06" comment since there are HR's hitting 300rwhp flat even easier than DE's. However, ultimately, the 'mod-ability' and peak potential still lies with DE. It was shared with sooooo many cars that the motor will probably still continue to develop in the next decade when Z prices drop. (how many 1000rwhp 300zx/supras were there in 98 vs now). HR has sealed its fate with 2 lower-volume model years and no parts sharing with other cars.

Horsepower is up 6.6 percent. Torque is down 2 percent. You can decide if or if not this is "much."

F34RL355

mexx the HR is designed to reduce friction of the pistons less friction less wear longer lasting higher rpm. get the HR it will last you longer theoretically if anything, many variables though

F34RL355

yeah HR's were prolly a test for the 3.7 HR's

Durability and reliability of HR is questionable. There simply are not many (none I know of) 100k mile HR's out there yet to know for certain. There are many VQ35DE motors in various platforms that have surpassed the 200k mark.

Lower wear? Not aware of this being true. The internals are no lighter, and the higher RPM's certainly don't contribute to less wear. The new 3.7s are VHRs and not HRs.

F34RL355

yeah variable valve they still very simmilar to the HR. im not saying they are more reliable but they def have pontential to be just cause u can red line 7500 doesnt mean u should on a dd at every light so sure maybe revving it that high may cause more wear but no reason to stick around there that often.

*Boose*

Are you all comparing reliability of the de vs hr? This is ridiculous, buy the 06 since power doesn't matter to you. BTW the auto 06's have a de not a revup.

You misread that post. He said if you DON'T care about hitting 300WHP with bolt-ons, go for 06. Implying that only the HR is capable of hitting 300WHP with ease, as opposed to the DE.

Buster-here

From wiki

The new engine block retains the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to 7500 rpm.

I had the choice and went with an HR.

im considering going with a HR, theres an 08 (base) model at my local dealer with 6k miles and comes with a certified 84month/100k mile warranty @ 21k
though it has no traction control, not sure exactly how much this will help. this is only a current consideration.

The 06 auto has the DE motor. This is quite adequate as a dd.
I have always redlined the 6.7k DE 6 speed and since I have both I have yet to be accustomed to the 7.5 k redline of the HR.
There is also the speed sensitive power steering [i believe] that feels different everytime I switch cars.
My 07 is a base and it definitely drives better with a big sticky rubber contact patch out rear.
