Do we really need a twin turbo?

hey, don't stop the dream with the ls3....go for the gusto! LS7 baby...... 700Z!

3100lbs + all aluminum LS7 = eye popping acceleration

heck, even the fuel economy is still there. I get pretty close to 29mpg highway cruising

Really, that things almost as bad as the Rx8's OMGOSH...

never said TT, just T. And i forgot about the Rotary, why dont they just throw in a rotary airplane engine and top off the Z with crazy RPM's TT's and extra Rotor's to call it a nice light very powerful Z....?

And a well designed V8? Be specific if you please? On what's causing the loss of weight? Aluminum block, heads, piping? Take away the V portion of the 6. Make it an inline 6, save some space, and add a big turbo instead of a twin coming off one sided exhaust ports instead of 2 sided. And i believe the weight issue will be saved in a 6 much more than that of a v8. The V kills the concept of space and TT issues...when one T's all you need in a well designed motor. Some examples would be the new BMW's, or the Volvo's both inline and pretty powerful.

YES!!!



But yes I'd rather have a turbo V6 then a n/a V8. Oh the possibilities...

Imagine the possibilities the extra V8 displacement would have with boost

And imagine that gas being sucked right down the fuel system!!! HOORAY GAS!!!!!

or lack thereof....

a well designed engine will be compact, lightweight, and have a good amount of displacement--see LS1's. they weigh as much as a VQ but can support twice the displacement. its when you start adding 4 cams, monster 4v heads, huge timing chains, variable cam sprockets, crazy intakes is where you start adding weight--something i am sure nissan would do . alum block, small 2v heads, 1 single cam in block to place weight lower in the chassis, less valvetrain, etc. that is how you make a well designed V8.

BMW and volvo both use twin turbos and the fact that an inline 6 adds too much weight to the front of the car makes it less desireable. also the single turbo will suffer from lag and driveability issues to make it a marketable solution to the USDM. not only that but even a single turbo OE application will add cast iron manifolds, extra piping, etc.. they all add weight.

from a modding perspective yes the TTV6 would be great, but i would much rather have more displacement to start with as you can make more power on pump gas. i am the type of person who would most likely change out all the OE turbo stuff anyways so i might as well start fresh.

V8 Z is not going to happen. So don't hold your breath.

thats what all the M3 guys said 4 years ago.....

i don't expect it or really care--especially if they put a VQ in the new 240 or whatever they are gonna call it.

And as soon as the V8 is dropped into the M3, there is talk they are taking it out in favor of a TT Inline 6 application. The next Gen M3 will not even have the V8. Too bad as it is a saawweettt V8.

Where did you hear that??

Nissan has played with the V8 Z idea many times in the past with previous Z models. They never actually did it except with a couple of Z race cars. With the way gas prices are and how auto manufacturers are struggling to sell vehicles don't expect to see Nissan make a V8 Z Car.

i have read a couple articles that hinted on a 2.5VQ that would also be in the infinity version of the 240.



i won't say it won't happen, but i can't see them going back to the I6. i can see them TT'ing the V8 though. or putting a V10 in the 3 and a V12 in the M5.

A single turbo VQ37 would make me get the new Z, immediately. I'd try hard to forget the looks, if it's ugly, though.

Hmm. That is interesting. I keep hearing so many things about that. Guess we will see. I like the idea of the 2.5VQ.... That bad boy should rev pretty high!

No BMW has stated they are going back to lighter weight cars. Dropping the huge, high HP engines. They specifically spoke of the inline 6 as the likely next M3 engine. They will just tune the heck out of it and probally drop about 420 HP out of it....

As you stated, however WHO KNOWS what they will do.

I think it looks awsome, and a 3.7 v8? sick..
