The GMC/Detriot Diesel designed 6.2L was never designed as a power house like todays cummins and ford/navistar power stroke diesels. Even in the light half ton chevy and gmc trucks it only had the power of a factory tuned 350 v8 gas engine, but with better fuel economy. You can get a turbo kit from Gale Banks for it, but it will never be a power monster without major beefing up of the lower end bearings and head work. You can have the injector pump timing checked by a reputable diesel shop to see if its up to spec, as well as having the injectors themselves "pop" tested. If the timing is off, injector pump is worn or injectors themselves are worn, it will make the engine really have no power. I just wish I had a 200 or 300 diesel in my NAS spec 96 Discovery, I hate this 16.5mpg I get. Cheers Mike
