Yes, as I said. The specs are speculative at best. They're just foggy (marketing) numbers, and none of them meet reality. The IP isn't the only difference between civi and MIL engines, and you've not applied any of the upgrades necessary to sustain greater power (including the transmission).

Forget the "specs", what you have, and what "they" have. It's greener grass. You have a 1992 model, which is essentially a N/A 6.5L with a little less displacement. It's broken. Fix it. THEN consider messing with upgrades and mod's. Just installing a "more power" pump will likely leave you with a 25 year old boat anchor in a short period.
