There is a Subaru-founded club which now has members with different cars called Forced4s. This club is in Cleveland, Ohio. I know it's not that close to Columbus, but the club was originally started by a group of Subaru guys and has expanded to have members with Evo's and Srt4s. The general similarity of the club members is that they are all 4cyl force inducted cars. During the summer and possibly still going on, they would meet up every Thursday around 7pm at Quaker Steak & Lube up in Cleveland off of Rockside Road on Valley View Road. There is usually a pretty good group of cars that would show up there every week. I'm not sure if they are still meeting right now with the weather getting colder and everything, but if anybody is interested, I can stop by there one Thursday night and see if it still going on. Either reply to this post or send me a message if you are interested.
