We run a 2400 car, we used to be class 10 and we LOVE IT! We actually have 3 cars and were working on converting the second to a 2400. Who doesn't love adding HP and almost DOUBLING Torque with out adding any weight. As far as being allowed to run other associations we haven't looked to far into it, but score officials have given us the verbal over the phone "I don't see why not, it is a sealed Ecotech" but we haven't talked to them since. If they say no. simply switch in the old Ecotech and go race.
Now. The reliability might scare people away as our finishing rate, as a class, this year wasn't good, but it was our first year and we were experimenting with these turbos. however, At this point a lot of the R & D is already done and we have a lot of the bugs worked out. At BWDC 5-6 finished first day and 5-5 the second. I hope you build one we would love the car count! (even tho it lowers our chances of getting 1-3rd $$)
