Its all starting to make sense now. I remember reading that the 'new' Focus was sharing much of its chassis with the world platform shared with other cars from Fords brands. Then, they put a nice 2.3L 4cyl in the Mazda6, which shares the same platform with the Focus. Then, they take that engine, call it a 'Duratec' and things are peachy. Then, they say they're making a turbo Mazda 6. And since it shares much with the Focus, now a real fast RS. Its funny how things seem sooo illogical at first, but the more info that gets released and comes to front, things make more sense.

This is looking very promising now. Making only one car, like the Evo for example, is expensive. That is the only car in the line to use its engine and drivetrain, But now, if they have a few cars using the same, or very similar drivetrains, that makes it much more feasable for use, and you get more performance for the $$$. I like it. This Mazda could be a real sweet piece. And, holy hell, if they would bring the RS over here, I'd be in hog heaven!!!! Please Ford, dump the SVT line for the Focus. WE WANT THE RS!!!!!!

ok guys quit bashing eachother about the level of our education here im only in high school and i know a hell of alot more than some of these older guys on here.... it makes no diffrence we are all into cars here and wether you like the new mazda or not you are welcome to say what you want to say about it thats what the thread is for to discuss it.... with that said the logistics of making a four cylander twin turbo have both good and bad sides. like it has been said before they would have to be in sequential order now lets just look at the plain and simple physics of it, if you make a turbo smaller the turbine will spin faster easier. this will be effective in providing boost in lower rpms and such when there is minimal exhaust flow passing through the turbo.When the exhaust flow becomes greater though the smaller turbo cant provide much boost because the turbine is spinning so quickly the compressor cannot compress the air fast enough (not to mention the heat that would be produced because of the greater speed of the smaller turbine) this is where the larger turbo comes in.the larger turbo can then take over at the higher rpms to give you maximum boost and this system dissapates most turbo lag that is present. the downsides to this can be: increased weight, a somewhat tricky planning of how to bypass the smaller turbo to the larger turbo with the ecu, and most important the sheer COST!!!! PS... no just cuz you have two turbos doesnt mean you automatically have more power as you can probably now understand from my explaination of what a sequential turbo setup is

 

oh yea forgot to add to the downsides list...... this setup is very hard to upgrade with out spending even more big $$$$ or maybe thats not a downside depending on what you're looking for

 

Like how to form paragraphs and using correct, READABLE punctuation????
Hi, I'm 4 days ago, have we met??? That was when people quit yelling at each other and normal discussion picked back up. Read ALL the posts in the thread, AND the dates and you will see that no one has yelled at anyone in quite some time.
Uh, yea, I think we all know how a sequential turbo works. Its not new. Its not the sequential part that was in question. It was the fact they might do this to a 4cylinder. Thats the somewhat odd part. Its a fairly big engine for 4cyls, so spinning a large-ish single turbo shouldn't be a problem. Or, if they were going for smooth operation and less lag, why not just turbo the V6??? That was the main questions people had. But, thanks for the refresher course on turbos.
