Suppose you really really want to own a 2006 350Z 6sp Enthusiast (probably a better buy, but...) or Track (... prefer Track trim at this time due to better value from mostly the BBK and RAYS rims upgrade) as a purchase (not lease), but you are debating whether to hold out for the 2007's MAINLY on the performance enhancements including a new VQ35HR engine and SOME RUMOR on noticeable weight loss (that we'll just have to see).

BUT WAIT, here's the twist. Say you want to turn your 350Z to become BMW Z4 M Coupe killer (some basic numbers on this car goes like: 3230 lbs, 330 HP, 262 lb-ft, 0-60 4.9 sec) on the street as well as on the track.

So most likely whether it's 2006 or 2007 350Z i'll be looking at having to add a turbo(s) or supercharger.

So then the question becomes, if you know you'll be mod'ing the car this way does it really matter whether you get '06 or '07 350Z? That is, if you know that the stock '06 and '07 will not meet your expectation.

Most likely '07 350Z will cost more and lesser immediate choices available for the aftermarket forced inductions.

And the way things are looking for me, i may end up having to order directly from the factory in Japan. If so then who knows, maybe my ONLY option is to get the 2007 model at this point in year.

And just few weeks ago i thought i would be just happy getting the 2006 350Z and have it go through similar conversion as the 2006 350Z GT-S Concept got, i.e. similar supercharger setup, since certainly that GT-S would be a close to if not certain, to be a Z4 M killer.

But now with folks all raving about the upcoming 2007 VQ35HR with dual inductions, now i'm just as confused, back to square one.

Thanks much!

 

i consider myself unknowledgable when it comes to FI...(i rely on having you guys there to point out my stupidity)...

but to what i understand, the "HR" in the new title is suppose to stand for "High Rev" or something along those lines... so IMHO a few extra RPMs would help the output of the turbos, if you go that route... SC and it will probably be another story...

but as you mentioned... with the release of a new engine, R&D has to take place as always, with the manufacturers of the aftermarket gadgets and gizmos... therefore, i would expect there to be a wait in the release of aftermarket parts... and like a large crowd, most new buyers of the car with the desire to go FI (if it doesn't already come with) will jump at the first kit to hit the market... (unless you ARE one of the knowledgable few) and as to be expected with a first released kit, there are flaws... flaws that the later kits will have thought about and corrected... so here we go again...

which kit is better, how is it better, what does the standard kit include, how much does it put out, is it "upgradeable" blah, blah, blah...

and if anybody is tired of hearing me ramble feel free to post a STFU pic

 

not a turbo expert either but here are a few things to consider:

1. if your real target is the z4m, you should be able to beat it without turbo, using N/A modifications with the new VQ35HR. People with 03-04 engines are able to get very close to M3 acceleration numbers with mods. I dont see why the new VQ35HR, with 310hp or so, wouldnt be able to do it. Would you blow it out the water? No, but if that's your goal..

2. I'm guessing the piping would be completely different for a turbo setup on this engine, so I doubt any current turbo kit would work. It would probably take some time for a ready-made kit to be available. Whereas if you got the 06 Z today, you could start going FI today.

3. Although it depends on the track, in many cases track performance is more than a big powerful engine. The weight, suspension, brakes, and driver are critical components. On some tracks, Zs can match M3s- stock for stock -even with a power difficiency. I don't see why a tuned N/A 07 Z, with suspension, brakes, and an experienced driver, couldn't match a Z4M...

 

I think the dual intakes make it worth it...but it is nice to have a new car over the summer and not have to wait. You could wait for the '07 to come out, then see if it's worth it. If not, you could get an '06 for alot cheaper since the new model will be out.

 

I want a high output VQ40DE!

 

I've read that the 08 G35coupe will be 330hp. So the Z would be a few more hp.

 

Why not just get a 04 z and turbo it and add a bunch of other mods for the price of buying a brand new 07. I am thinking of doing this, you can get a 03-04 for 18-23k now days with not a lot of miles on it. Slap on a turbo, some wheels, suspension, slight tasteful exterior mods and bham you have a very quick, very unique Z for around 35k. Of course you would have to do some budgeting like maybe picking up some used wheels/suspension/etc. but u get the idea.

 

I had this same dilema and I had a simple answer for myself

A) IF I am going turbo --- I am building the motor
B) If I am building a motor I could buy an 07 longblock to start with and sleeve and add the new heads if they turn out to be good
C) If this is the case I can have the motor built, ported&polished heads installed and turbo setup engine dyno tuned before it ever gets installed in my car which minimizes down time

For all those reasons I am now driving an 06 Track that will get basic mods and eventually receive a built turbo motor after the warranty is up and I have the money to burn

For all intensive purposes a well modded 06 z should keep up with a new M coupe and in all reality who cares? I love my Z and if I wanted a car I could mod and make mad power with a track I owuld have bought an EVO --- instead I drive a comfortable, powerful GT car with killer looks and a motor with tons of potential --- will I race an M coupe, maybe but 99.9% of my time behind the wheel will be on the way to work/home/dinner with my significant other

If I was tracking my car every weekend and autocrossing every season --- I would wait for the 07 as it will no doubt be a better Z in every sense and the numbers dont lie 7500 rpm stock = stonger rods, better heads, better intake and exhaust --- a true modded 06 with a warranty and still following Solo rules

Most members dont compete and probably wouldnt notice the difference anyway --- I wish I had the time and money to track my car but at least I can enjoy my drive to work

 

Get an 03 and put in the RB26DETT.

YEAH!!

 

I am sure someone will figure out how to modify a VQ35DE to get the dual intakes...

I am not "forced induction guy" but having a higher compression motor isn't what alot of FI people want. Most want a low compression motor.

 

I don't know of any single turbo car that works in conjunction with a duel intake system intake manifold

 

if you want to go FI you are better off with the current a 287hp b/c they have been around the longest and the tuners know the most about them...

The only reason I could see waiting is to see if Nissan puts in stronger internals b/c of the higher rev limit... but if you are going to go hard core built you will be changing internals and lowering compression anyway... really no reason to get the vq35hr that no one knows anything about and be the first to break it down.

 

The 2007 will be better than the 2006 so it would be a good idea to wait.
The 2008 will be better than the 2007 so it would be a good idea to wait.
The 2009 will be better than the 2008 so it would be a good idea to wait.

No.. the whole overhaul they've done for the 07' engine is something totally new from a performance perspective, they normally only change aesthetic parts of the car in regularly run model years.

 

I bought a 260Z new so my perspective of the Z is different than that of new converts. Every couple of years Datsun was adding 200cc (2,400cc, 2,600, 2,800cc…)Still enthusiasts were buying the Z in its present form. If everyone waited for the next and best Z, then no one would be driving a Z.

 

id like to see if the 07 Z will have the same sexy exhaust note....sounds corny, but the exhaust note on my 03 is one of the smaller reasons i wanted the car. well see

 

not quite worth it

 

Thanks everyone!

I'll be waiting (patiently) for the 2007 350Z... hope it's worth the wait...

 

when will it is released?
