Z35 motor theory
 

In the past it has been debated, what engine will the Z35 get? In one of my threads I made a poll where the forum voted on what they would like to see. Choices I provided were a hypothetical 2.5 turbo 4 banger, 3.0 v6 turbo or keep the 3.7. Some felt the middle engine had no hope of being produced. There was no credible info stating Nissan was working on any new engines and the ONLY data at the time was a 3.0.turbo_diesel by new partners Mercedes-Benz.

Well it turns out Benz has a new series of turbo engines coming out.
One is a 2.0 4 cylinder turbo producing 241hp & 273lb tq.
An AMG version with 355hp & 332 lb tq.
Finally a 3.0 v6 turbo rated @ 329hp & 354lb tq.

Lets cross out the first entry. It sounds like what would possibly end up in the IDX Nismo. The other two seem more credible to the Z. Especially my previously speculative hopes for a 3.0 v6 turbo. Though I was hoping to see HP numbers closer to 350 or 370. The torque number is a prayer answered fir the Z.
I'm sure it would be easy for Nissan to tune this out to 370hp & 355lbs torque. If this kind of power was lowered into a 3100-3200 lb vehicle? With some suspension help from AMG, this Z once again will rival v8's with more than half the displacement. Will MB throw us a bone for the Z's powerplant?

Thoughts?

Mercedes did it for the Chrysler Crossfire (supercharged V6). Good combination I,ve seen on an immaculate 2005 build do a 1/4 mile in 12.56sec!
But - for the Nissan purists ( me included) Nissan have the capability of providing something of their own design - it will inevitably be up to their boffins to gauge if there will be a return on investment within the market they are to aim at.

My 2 cents

I doubt it will be the same engine that they are putting into the CLA45, so that leaves the 3.0 V6.

Personally, I want it to be a 2.4L turbo, for reasons that should be obvious.

Z35 motor theory
 

The AMG 2.0 turbo would be a beast but I have major concerns about the reliability of that engine. I'll take a v6 running low to normal amounts of boost instead of the 26 pounds that monster AMG shoves through itself. In the end I want more power but I also want reliable.

Not that they would, but how would you guys feel about a hybrid? Think KERS/F1 style.

How about an AMG version of the v6 turbo :stirthepot: but what I would really like to see is a detuned version of the vq30dett that was used in nissans super GT car

Part of the reason I bought a 370Z was the idea that it was a Nissan. Reliability ratings were good and service cost is ... well ... Nissan prices, not German prices. I am not sure Nissan would be able to pull the same reliability from a hot rodded turbo 4 banger. I don't like turbo's either. I do like the idea of hybrid with combined hp of about 375 to 400. Now that would be cool and with current tech really easy. However, not sure about long term reliability. Have not done that kind of research.

This is a toughie. I think no matter what the weight of the car is, they will insist on power values that are higher than they were before -- that would knock out the 3.0 turbo option, unless they can bump up the power a bit.

The more powerful AMG motor may be an option, but I expect it to be pricey, and like the IPL G or Q or whatever it is now.

That said, I am expecting the new Z to be only marginally different from the current model at this point -- I'm open to being mistaken and (hopefully) pleasantly surprised, but the new G is pretty much just a refined version of the old one, and the Z tends to follow that, so...

crossfire's biggest fail (besides the appearance) was their wobbly gearbox. :ugh:

i honestly could careless if benz makes the engines. i personally like the VQ engines.
that's wat makes nissans a nissan imo.

Inifiniti is already selling the Q50 with a MB 2.0T outside the US. So, replacing the 3.7 VQ with another MB engine is possible.

if i wanted a benz engine infiniti, i would just get benz.

another reason why ive been looking at lexus these days. somethings just needs to be japanese if buying a japanese car.

Ya think the Germans are bitching about their 2.0T being built in Tennessee?

Nissan builds great motors/drivetrain. They do not need any help. Why would they outsource what they do very well. Not sure what I would like to see. 4 banger= NO.

Since i come down a long line of psychics(or phsycos can't remember) i will tell you what it will be. It will stay a v6 and the power out put will be around 370 and the design will pretty much be the same.

kthxbye

shittt, that's the same senario we had with the f-king steering locks. :shakes head:

This is a very smart financial decision by Nissan. Infiniti's for Europe are manufactured in Europe so the logistic's in using the MB engine makes sense.

Correct me if I'm wrong but the G's, Q50/60's, Z's and GTR's for the US are all manufactured at the same plant in Japan. If Nissan want's to keep the same business plan, shipping MB engines or retooling their whole factory to assemble this engine with the majority of parts coming from Germany may not make financial sense.

My guess is an in house made Japanese/Nissan engine (probably some form of VQ/VR), will go into all the same cars currently being manufactured there, with the GTR having the best. Having some form of boost in a new engine maybe possible, but with direct injection and newer friction lowering technology, a non boost V6 engine may still be a reality.

are they going to start building infiniti's for USDM that use the benz engine at the TN plant? :confused:

one of the issues i have with benz is reliability.

:iagree: I hope not.

I believe if the Z was going to be only marginally different. The next gen m,odel would be coming out this October instead of us dealing with unknowns.

GTR 3.8 non turboed motor? That would be sweet. But I thought they said they were definitely looking at doing a boosted 4 banger due to wanting to be greener? I'd read a statement a whole back from the head honcho I thought verifying that?

Zdayz 2014!!

Comparing Nissan torque numbers to Mercedes. Then comparing exhaust notes between Mercedes v6 and nissan v6. I say Nissan needs a lotta help these days on lower end cars. MB already uses almost identical engine technology. We would be getting from Mercedes is refinement. The sounds and torque that should be me in a proper sports car.

Maybe... they could shed weight, change the body panels/front fascia, suspension, brakes, etc to create a very different car, and keep the same motor and trans options tho'.

What's the latest on when we're supposed to hear something? Not til January?

I dont even know brutha. We were supposed to see the new Z a few months back and instead we got the IDX.


I propose Nissan does the final tune on the MB motor. That's probably where most of Nissan reliability is anyway. For those that think an MB engine would be unreliable. I think you guys should look at Mercedes Benz reliability since 2008. they are not perfect but for germans they are pretty reliable. Porsche has come along way in this department as well. it's BMW, Audi and Volkswagen that strive to keep the unreliable reputation alive.

From what I heard from a doctor:

There will be an engine manufactured in TN that will go in the lowest model Infiniti. What MB does with the same engine, is up to them.

Also, look forward to the first Infiniti model vehicle built outside of Japan to be produced in good ol' TN. Is that a bad thing? Not when you figure out that the Japanese have decided the quality of vehicles coming out of Smyrna is good enough to carry the Infiniti brand name.

Now, back on topic I wish I could get some intel on the next Z but I'll speculate with the best of them. The next gen GTR will have a new engine producing 800hp. That leaves this motor as a left over that could be shoved into the Z35.

I could see a de-tuned version of the GT-R motor offered in a "super nismo" IPL -type package -- it won't be cheap tho'.

I'd say the odds of that happening might be related to what (if anything) Toyota does with their FT-1/theorized to be new Supra car.

If Toyota rolls out a N/A and a turbo version of a new Supra, like days of yore, I could see Nissan doing the same with the Z to compete.

If there's ever a new Supra, it will be 100K+ and a direct competitor with the GTR.

I bought this car because it is a Nissan built in Japan. I was tickled to death to see the first letter be a "J" in the Vin. Cars built and assembled in Japan are so much better than being assembled anywhere else. My wife has an 03' Maxima that was built in Japan. It was much better than my 2008 Maxima I just got ride of. I have been driving Datsun/Nissan's for 27 years. Exhaust note has nothing to do with how an engine performs and it's reliability. I personally would like to see a 2.4 liter straight 6, twin cam with variable timing (exhaust and intake), direct injection, and for our Nismo, a turbo charged 2.4. The Datsun/Nissan straight six engines would run forever with very little maintenance cost.

No flippin way they're putting a 4 banger on the Z35. My guess is V6 turbo or a larger displacement than the current

If they turbo V6 the Z, they'll kill the GTR. It's either going to be a turbo 4 (massive fail) or another NA v6.

My 2c

I've owned 2 infiniti's and 5 nissans. I know that nissans are generally good quality for the m obey. but I spent 35,000 dollars on a sports car that sounds like a sewing machine. That bothers. Both my G's sounded awesome. The Z and my Altima 3.5 nearly sounded the same. That's not good to me. I shouldn't have to spend money to make my car sound like a sports car when it is in fact a sports car. When buying an enthusiastic vehicle, yes exhaust note mean something to me. Torque means 10 times more to me. The Z gets a D+ on torque for the manual and the C+ on the automatic. Let's push it up two an A+.

I'm about nissan progress, not about nissan fanboy.

the current 3.0 6 cylinder turbo is rated at 329 horsepower. I don't see how it will cut into a 600 horsepower GTR

^ Exactly and someone stated earlier the gtr is getting a rather decent power boost so there is plenty of room for even something as crazy as a 500 hp Z.

No turbos please! A higher revving, lighter weight with a more balanced power band engine mated to a 2800 lb car will wipe the floor with anything in its targeted class while meeting tighter EPA regulations. Throw in a KERS type boost system good for a 1/4 mile run and you have something worthy of the Z name.

A weight reduction will be key to obtaining better performance and economy. Just hope nissan doesnt do what ford did to the mustang and add weight

LOL, Let's just agree to disagree. Modifying to your likes has always been part of the game. I have owned the following Z's.

1974 1/2 260z
1975 280zt, currently still have.
1978 280z
1980 280zx
1983 280zx 2+2
1987 300zt
1990 300ztt

So, I have had just a few of them. I am not counting any of my other Nissans I have owned. Nissan fan boy, ah, NO. I do love a Z car. Never did like the 350z though.

Agreed, Z 's have become far too heavy.

Personally, I would like to see the Z lose about 400-600 pounds. If it did that I would be fine with engine numbers.

We need a direct injected, higher compression NA 3.8L V-6 out of the GTR that's not hand built. 400 hp & 300 tq and the car needs to weigh 3K. 25 mpg combined due to the direct injection. Yeah... better stock exhaust note. Oh yeah, and I want those red Recaros out of the '15 Nismo. That would be $$$.

That don't sound to bad. I wonder how much more the new Z will cost.

The same, maybe a little less. Gotta compete with the Mustang and Camaro. I love the Z, but a Mustang GT is a great value and can be built to handle.
