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?

one of the issues i have with benz is reliability.

I hope not.

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...

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?

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.

jaedub · 07-22-2014, 09:13 PM

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

DjSquall · 07-22-2014, 09:20 PM

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.
