Gawd Damn. I want one.

Wow, so all the rumors (which many thought to be too wild for Mazda) are true. Damn, the LGT just got some good competition.

Now, hopefully this means that Subaru will give us a 6-speed in the LGT.

Bah. It's a Mazda. :monkey:

No offense to Debbie... :wink:

Just because you have a crap one from the years before Ford bailed 'em out, doesn't mean they're all junk. The new 6's, 3's, Miatas, and RX-8's are awesome cars!

Wonder if their AWD system will be any good.

Says the man with a Ford.

:lol: :lol: :lol:

omg, did they say turbo and AWD and Mazda in the same sentence?

OOOOO!! Go Mazda! that makes me giddy to think about it, although I wish they'd have done it with the 3, but hey, its all good!

Wow, direct injection, should be REAL good for tuning... But I dont like the Mazda 6 interior, I'm waiting more to see what the Mazdaspeed Mazda 3 will be like.

Any particular reason why? DI is good stuff and has far more efficient combustion, but I'm not seeing how tuning it would be all that different than manifold injection.

It won't necessarily make tuning easier... but since it resists detonation so much more, you'll be able to take it that much further and get real power out of a motor that will last longer than 5 hours w/o a rebuild.

I guarentee this DI/turbo motor is a result of the World Challenge TC cars getting to use forced induction in 2005. Mazda has spent an assload of money on making the 3 competative in Speed TC. Hopefully w/ the new rules and use of the 6, Mazda street cars will start to resemble the TC cars performance-wise.

That'd be awesome. I wonder if Subaru is going to get into the TC w/ the new FI rules.

Oh I'm sure the WRX will start turning up in TC. :twisted:

Hey Matt... wanna convert my car to TC rules and race that? :lol: ...wait, I'm only half kidding. If I could afford the time away from work, I'd do it.

This is a JDM Impreza race car, with custom direct port fuel injection on an N/A 2.0l motor... Note the power numbers:

Also take a look at the power numbers from other direct port motors. (I dont have any links for those...)

Don't tempt me...I'm seriously thinking of doing something insane in early 2005. :twisted:

The power numbers are impressive, but that wasn't what I was asking; it sounded like you thought tuning a DI engine was somehow different than tuning a MPI engine, is that the case? If so, how is it different?

Unless you wanna be DFL every race, it takes way too much money to compete in World Challenge. You should go run with the guys in USTCC. 8)

That series is all but dead...

Really? There seemed to be quite a few of them buzzing around at Sears Point...

DI opens up a whole new set of parameters for fuel tuning. With standard FI, you only determine the length of injector pulse. With DI, you determine timing, length, and sometimes even run multiple pulses in one combustion cycle. And the REALLY cool part is that it open the door to 500hp cars that get 45mpg on the way to the track. 8) Also, would a second, very small, very late fuel injector pulse be a better option for antilag, rather than severly retarded spark to ignite a larger mixture? It's not like you'll get knock in your uppipe...

Kevin beat me to it. With direct port fuel injection, you basically have TOTAL control of fuel injection electronically. With a skilled tuner, you could do whatever you want with it :)

The multiple pulses on different strokes are pretty cool, that sounds like the one big difference. I totally agree that it's good stuff that will open the door to monster engines that still get good mileage, but it just seems like programming it wouldn't be a huge step from what we already have. Even in the Ford EEC-IV (1987 vintage) I can change injector pulsewidth and injector timing.

Mazda must know I like this car:

Got this email:

Thats cool. Does this mean you get to go test drive it?
