difference in pre 99 and post 99

[880lbs feet torque]

This might be a dumb question but can someone explain to me what the difference is between the pre 99 and the post. i personaly own a pre and hate trying to buy things and its for a post. Their is a twin turbo kit i would realy enjoy getting but dont know what i have to do to retro if i even need to. thanks

I think Early 99's have a wicked wheel, Intake pulls from fender,waste gate. I own an early 99 im sure someone else can fill you in

Early to late...

Early have smaller injectors, smaller HPOP, smaller turbo, Intake is differant, Intake manifolds are smaller, Y pipe is differant, Exhaust up pipes, and colector is differant. Mirrors do not extend, most have all metal Intercoolers, but the tubes are smaller, no insulation on the drivers side IC pipe. Differant steering box and pitman arm.

CSIPSD nailed it except you could get the extending mirrors on the early 99 too I know cuz my old work truck was an early 99 and it had em

now for another stupid question what is a hpop? this is my first diesel. i use to own all gassers. i use to have a 1967 ford fairlane with a build 311 and 125 shot of nos and got my *** handed to me by a cummins from light to light, and being my blood is blue through and through i had to get a stroker.

You could add them after 99.5... But they were not made when the early 99's came out, just the great big long arm ones...

OK guys with first diesel: Im a old diesel operator and owner Fords, Benzes, and a dispicibul chevvie bad news, the hpop is olny on a HUI system, what they calll IDI or indirect injection is kinda a misnomer but one of those uses a pump/distrubtor geared or timming chain run on the engine, They have the injectors on the top that look like a big steal spark plug with a line running to the injector,from hte distrubtior to each injector. thye both have the same outcome ie vaporising the fule... OK the Hpop replaces the pump distrubitor setup. FDDTS - Tech Publications this a sight that might help give you an understanding of a HUI system.... Hope this helps you <<<<<<<BILL>>>>>>>>
