Mazda3 2.0L with 148hp. Howd they do it.
Okay, I like all the pictures and I think the thing is going to be a good seller, but for all of us that are not going out to get a brand new car, could someone explain the engine mods Mazda did to increase the hp some 18 points over a regular current 2.0L. And most importantly, could we use these mods to improve our current rides?

Much better architecture in the new engine. And 148hp out of 2L isn't a huge output (considering Acura gets 160hp out of their "mild" RSX motor).
By architecture, I mean everything from valve size, valve angle, combustion chamber shape, intake and exhaust designs, cam timing, etc.

I asked a dealer in the Toronto, Canada area and it said the new 2.0L engine will only be 130hp. Makes me wonder if it is the
"new" engine is really new.
However, if hes wrong and we do get the 148 or 150hp engine, it will be Mazda's new MZR line of engines. Completely new engine from the FS-DE. The MZR has intake manifold in the front and exhaust in the back opposite to the FS-DE. The setup is like those on newer small sedans.

intake in the front exhaust at the back......hmmmmm sounds like the corolla engines (hopefully the can match some of the fuel efficiency of the corolla engines too). I wonder if this will help the exhuast gas flow?

Ok, a departure for Toyota from the norm now too. Funny, how Honda did things the exact opposite since its inception and they have now just within the last year or so reverted to the other way around in line with rest of the industry, just as Mazda and Toyota flip to Honda's way of doing things.

The new Honda K series engines have their intake manifoldin the front and exhaust manifold in the back I think.
Moving the exhuast manifold to the back serves two purposes I know of. First it allows the car to heat up the catalylic converter more quickly for lesser emissions. The majority of harmful emissions is produced at startup when the cat is cold.
Second, its more quiet at startup since the intake manifold is located away from the passenger compartment. Don't really understand this since I heard it from a sales person.

It is the same motor that the new Focus is going to have, as well as the Volvo S40 and any other 2.3 liter Ford Motor. It believe it was designed by Mazda so it will have Japanese integrity. Go drive a Mazda 6, 4 four banger and have yourself a test.

The 2.3L in the Mazda6i is a good motor! It makes pretty good power for a heavy car. I am still floored that such a progressive company like mazda denies us the reliability and performance of a good roots-style blower. They get a lot of power out of their fancy intake designs, but cramming that air in there will make a lot more.
