The turbo guys are making more HP than the JRSC. You will more than likely have less problems with the JRSC, because tuning isn't quite as in depth as turbo systems, the JRSC still needs to be tuned to perfection to be reliable, but tuning isn't as tuff. Maintanence is slightly higher on a turbocharged car. Both can be reliable, but you'll have to make sure everything is precise, there is no room for error in the FI field. Drag usually makes more power than Fmax, but the quality is slightly lower from what I've heard from other users. I built a custom kit, and had my block built for it. If you have any questions you can PM me, and I'll let you know.
