autocross question

What is the difference between DM and EM? I've gone through the SCCA rule book, and it doesn't separate them so far as I can tell. I know my car is no longer SM, and I know it's either DM or EM...

Car Info: STi (cornering, accelerating and braking hard).
The biggest difference is the engine displacement size. DM is for 2 liter or smaller engines and EM is for engines larger than 2 liter.

The rule actually specifies engine size as 2000 cc or under for DM.

Alexis, did you get a stroker kit? You should run in EM, that's what Rudy runs in.

Aww, man. Not again....

Well it doesn't really matter now. I'll be leaving again before the next autocross. At least I'll be going to Japan and not Africa this time. That means I'll probably be shipping back stuff from the parts department again. But what else do I need that I can only get from there...?

Yeah, the engine has changed a little . I was hoping to put it in action in the next autocross, but I guess I have to wait a little longer.

2-3 months.... When does the autocross season end? Will I still be able to make it? The scca site only shows to Dec 16th and I'm not due back until just after Christmas or so.

I'm jealous. Still have that APS turbo or something else? Curious to know what you've conjured up this time.

The turbo got upgraded too. To tell you the truth, I don't know exactly everything that is done to my car. I asked the people who know what they're doing (Ryan, Davin) to make the car better. You saw the results of my "handiwork" - slowest STi on the island . It's all power and "beauty" mods though, I am still running stock suspension.
