 they had a 6.9, 7.3, 7.3 turbo and then the 7.3 turbo powerstroke. the 6.9, 7.3 and 7.3 turbo all had mechanical injection, not oil psi opening injection. the powerjunk had an additional high pressure oil pump to open the injector during injection sequence. the 7.3 turbo was the last true navistar diesel engine ford used and was nothing more than a 6.9 bored/punched out to 7.3L. i used to have a ford dually that had a 7.3 non turbo
