Guess I'll just use this as my introduction. I'm new to ZX3's, but not to autocross. I started autocrossing in 2005 and have owned/autocrossed a lot of cars since then. My most recent autocross car was a 2005 Scion TC built for RTF (HS index.) Finished mid-pack with it at nationals, which was about where I'd hoped to end up with a non-Mini Cooper. I've considered prepping the car for STF, but after more research I'm realizing there are better cars for the class. I loved the torque of the Scion's 2.4L for corner-exit, but the weight was the real concern for me. In RTF trim, I got it down to 2776 pounds (race weight.) Which isn't bad for a starting curb weight of 2905 pounds. However, I think a full STF build would only get the car down to around 2700 pounds. That's still pretty heavy for a car that can only run 225's on 7.5" wide wheels. Mazda3's have similar power and slightly less weight, but are still a little on the heavy side. Enter the 2.3L Duratec ZX3... 2600 pounds and 149hp, stock. In STF prep, it seems reasonable to think it could get under 2500 pounds and over 160hp, (based on dyno charts I've seen.) 2.3 Liters means the car should have fairly decent torque. Also, the dimensions are pretty good. Somewhat short in height and length, and also pretty narrow. Operating costs for STF should be pretty low, and the car has enough power that it could still be fun on a road course. All of these things together, have really sold me on this car.
I've got a line on a very low-optioned D23 ZX3, and if all goes as planned, I should be picking it up next week. I'm pretty excited to build this car, as I think it could be a very strong contender in STF. Especially on larger, power courses.
I'll hold off on sharing my build plans until the car is actually in my driveway. At that point, I'll probably be asking a lot of questions on this forum. I'll also try to get pictures up once the car is officially mine.
