Hey man, I have a 96 JDM Spec R too. It sounds like your timing blew. You said your car just shut off, no power?? Sounds like you couold have bent the valves really bad. Is your timing belt in tact? Check out your water pump pulley and and all that stuff down that way. Take your head off too if you dont see anything around the timing area. Let me know. Sounds like timing though. Later.
