Yep, you're cooked. SM is the land of enigne swaps and FI. Show up, talk to the other STS guys, and then register. Odds are if it's a small group they'll be cool and let you run with them. If it's bigger or they're just very serious about the rules, or you just want to run by the rules, then go to SM. It's not like you can't compare your times with STS anyway. I like it more when regions let you run wherever you want, within reason. Others like sticking with the rules very strictly. Say, optimized TB, CF hood, no cats, etc, as long as you don't have a faster car. If you were in an '89 Civic Si, then you would have to worry about an unfair advantage.
