By the way, the overall size of the engine bay, not the engine, would dictate space. If it was senquential, and you actually knew what that was or spent the time finding out, you would realize the turbos are mounted in series going into the intake manifold. Besides piping, the overall size wouldnt be an issue, especially in a car as decently sized as the Mazda 6. Perhaps your assuming their twin setup would be much like that on a V8, with one turbo serving each bank of cylinders.....
Now can anyone with "more knowledge" chime in witha reply...

wow didn't realize that you're so knowledgable, maybe Mitsubishi should hire you to twin turbo the Evo then. hahaha you guys are so funny, i guess we'll just wait and see good this twin turbo set up on a 4 cylinder is. I mean since you're so knowledgable maybe you can show us designs on how this whole setup is going to work. Hmm me not educated, sorry I finished Graduate school 2 years ago, so i guess i dont have as much education as you.
Oh yeah, I don't ever remember seeing a college course for Turbo Machinery hahaha, guess I went to a whacked college cause my school never offered "Turbo Machinery"
Okie dude
you keep it coming with the fluid dynamics etc.... you know what you're talking about.Nebo

A sequential turbo system is actually pretty simple to understand. Basically you have a small turbo that spools quickly and a larger turbo that picks up where the small turbo leaves off in the upper rpms. So you'll get 2 kicks in the pants, one in the lower rpms (1000-2500) and one in the mid rpms (4000-5000). If you've seen the dyno for a VTEC engine, then think of the plot as having two VTEC kicks.
right, i kno its an attainable system, but from a cost perspective and also for production, I don't think its feasible. I mean, anything given enough money you can do. Heck but to put a twin turbo in a 4 cylinder and to keep it price competitive with the Evo/STi, I can't see it being done.
Also, if this was feasible, I would assume the STi' when they were made for the U.S market to go twin turbo too since they have the bigger motor.

I think that it was the rumours flying around and people were saying its twin turbo. I think the prototype they had it on was a 6 cylinder twin turbo set up pushing 350hp or something like that... think thats why people still think its twin turbo even though its not.

Umm I would like to be the first person to call Bull**** on this one. Twin turbo on a 2.3liter four. Are they saying they can twin turbo a 4 cylinder car??? and with a twin turbo, you better be making 300+hp.
the rx-7 had a rotary twin turbo engine. maybe it's gonna have a rotary?

Though I doubt the production 6 will see the twin turbo setup, I for one am really looking forward to this car. I really like the lines of it.
Now, if it were a twin turbo setup, it would most certainly be a sequential setup, but simply because it would improve drivability.. How many "big horsepower" guys really concern themselves with low-end drivability, heck their willing to spool at 5000 rpm's if they can make their numbers.. Remember, if they use a system like that, their engineering it to meet their goals, not for the potential for upgrade, it just happens to be that when components are engineered, they are generally designed to be much more stout than what their intended purpose is.. Anyone who does civil engineering or mechanical engineering would understand that.
But that is a little offtopic, I really love AWD cars, and would like to see more of these similar little rockets show up..

im all for it, i mean if they can really produce a turbo AWD vehicle, i'll jump on and buy one. 
I just hope if it does come into production, it won't cost an arm and a leg.

v8killer: don't think the new Legacy GT from Subie is Twin turbo... I looked on the site and I think it would have mentioned it. But I could be wrong as usual
