My family owns a 2000 GTX DI that has a blown motor. We purchased it used ~15 years ago and have never done any major motor work to it. It currently has just under 300 hrs on it. It ran rough for several years before finally refusing to start last year. A local shop did a compression test and I forgot the numbers but one cylinder was good and the other was less than half what it should be. At that point they said a new motor was needed and we took it back home.
After much reading and self-education, I suspect a fuel pressure issue resulted in a lean mixture that eventually caused the engine to fail. I am contemplating taking this on as a project. I understand how important fuel and air pressure are to these DI's, so I know some work is likely required there. As for the motor, is swapping in a rebuilt motor the best choice at this point? Or do I need to open it up and diagnose the problem further? I can't rebuild it myself but am pretty confident I could swap in a rebuilt motor. Overall I am pretty savvy but not with internal engine work.
