I guess, but if your looking to spend $3000 on a modification and wanted information or opinions on it, I'd imagine you'd want as many as you could get.
The JRSC is a good piece but I don't know too much about the company anymore. Oscar Jackson was one of the first real import guys working on Honda's and whatnot long long before it was popular. I heard a few years ago that he sold the company and people who took over are more interested in profit than quality and the parts and support have really slipped. I don't want to badmouth or give anybody a bad name but this is what I have heard. Like I said, I knew 2 people with them and they did well with them (13.7 is nothing to laugh at in a street car that orignally made between 100-125 hp). I actually considered buying one for my '98 EX before I built my hybrid hatchback and just started daily driving my '98.
