I used the EPS IMS solution after doing extensive research on all of the options available. Mine has been in for about 9K miles at this point. I run the heck out of my 1997 and thus far no problems. It only had 40k miles on it but I was concerned about dependability so I replaced all the rubber coolant hoses, the front motor mount, the Air/Oil separator, the water pump (was starting to wobble), the plugs and plug tubes, the rear main seal and the fuel and air filter and anything else I could think of. Here is a video with a cutaway of the EPS IMS solution.
