welcome to the board. 
either you left something out or you're the most cryptic person to post in a while. there is no way for anyone to answer your question about if the engine sounds healthy. fix the MOP issue, get a compression test if you're worried about the engine's health. if it checks out, then get a full tuneup and start from there.

One person's version of how to change the OMP... https://www.rx7club.com/3rd-generati...my-how-675341/
If your car is a single turbo, it may be easier from above, but regardless it might give you an idea of the job. As mentioned late in that thread I recommend new OMP 'O' Ring and using new copper crush washers for the lines.
I am a little curious though....how do you know you need to change the OMP? If you have a single turbo, you SHOULD have a standalone ECU. And with an aftermarket ECU, you wouldn't get a CEL to alert you to a bad OMP.

^Although installing the PFC will take it out of limp, I agree with your tech and would still replace the OMP. You can probably source a good used OMP from the Parts For Sale section for < $50. Otherwise, you MUST pre-mix. Then, BEFORE driving your car, install the PFC and get it tuned. I can't imagine the stock ECU is adequate for ANY single turbo and driving the car that way puts you at great risk of running lean and blowing an engine.
As a new owner, I highly recommend getting a copy of the Factory Service Manual. Downloadable versions are available in the FAQ sticky in the 3rd Gen. section for free. I would also spend a few evenings reading through those same stickys. ALOT of information. The car is not your parent's Honda.
