There is currently a turbo B16 '93 Civic (at least I think that's what it is) with a DSM Talon Turbo/Intercooler campaigning in our region. It's run by one of the most successful teams, the Holy Rollers.
They've won a lot of races. I believe last year they ran an Integra with a CRX engine...it was about a second faster.
Yes, our car is currently over-valued (imo), which is why we're looking at other options. In previous years car value was a big black box where no one had a clear idea where anyone else sat, so we were pretty comfortable with ours. Now it's more cut and dry, and it's easy to see there are cars that are under-value with performance potential.
EX: Fox Body Mustang has a $200 starting value as a V8 with ~280 HP. An FB RX7 has a $200 value as well. There are many "out of the box" cars that are ~$500. The E36 BMW platform is hugely successful and requires almost no real upgrades to have a winnable car. The E30 platform is very popular/successful as well.
The charm to this racing series, however, is that you're on track with 50+ teams and maybe 30+ different types of cars. It's pretty special to go 3 wide into a corner with a mustang on your inside, a turbo civic in front of you, and a BMW trailing just behind you.
@Goshin - We did not do the steampunk theme, since we ran out of time. Since then we haven't run any Lemons races, so we don't really need a theme. We would fucking love to come to CoTA, and the entire series wants to run it for an event, but their track fees are fucking ridiculous. Especially since you have to pay for every square foot of ARMCO you manage to twat your car into (at a hefty premium, many thousands of dollars per foot, iirc). Believe me when I say that's completely unacceptable for this format of racing. Maybe once they pull the yard sticks out of their asses we can run an event there.
