I had my engine rebuilt with OEM parts when I first purchased the car. It cost more than twice as much as a JDM engine. At the time, I didnt know about JDM's and thought rebuilding was my only option.
Ive put over 120k miles on the engine since with minor problems & normal sensor replacements. Ive purchased rebuilt engines in the past with okay experiences. I would probably buy an SR20 remag engine.
