HPOP, Yes! Worth a few more ponies and idle is quiter.
Turbo, no so much. OBS trucks have the Better compressor wheel. SD turbos are westegated too.

umm sry what is a hpop? i dont know that lol
HPOP= High Pressure Oil Pump, it is used to fire the HEUI injectors in a powerstroke.
Basically they took a simple engine design and made it complicated.
Wouldn't the wastegated turbo spool quicker and in theory give you more grunt off the line?

there are advantages to both.
if youre gonna run a SD hpop make sure you find the "******" cover pump with the 17* swash plate.look at the rear of the pump if the cover inside it doesnt have a bulge in it,dont waste your time or money.the nonhumped pump is the same as your stocker.
the 99-03 turbo will be an upgrade for you.toss a stock 94.5-97 compressor wheel in it and itll be fine.itll handle a few more PSI than your stocker without blowin the bushing out of it.IIRC the SD turbo is a ball bearing turbo where ours have a bushing.the stock turbo doesnt like more than around 26PSI where mine has seen 36PSI daily wich is why im on turbo #4.make sure you get the up pipes,collector,pedistal,spider,intercooler p[ipes and intercooler if you can afford it.dont need the spider,tubes and intercooler but might as well grab them.not sure if the stock intake spider will work on the sd turbo or not.not sure if the exhaust manifolds are different or not either but something tells me one of them is different than the 94.5-97.

The SD turbo and OBS turbos have the same bearings. Some the aftermarket turbos have BB's
93f250idi how much HP do you want to put down the the Rear Wheels?
You will get a quick spool with a smaller turbo. The OBS turbo is a 1.15 and that a good size for stage ones. The van turbo with it's smaller turbine of 1.00 will move the truck of the line real quick like. Also with SD turbo the wastegate that tends to leak of a high HPs so a bigger head os needed then.
In mid 97 I think was when the changed the exhaust manifolds. The newer style flows better.

if thats the kind of power youre looking for,you need my truck.its acheivable but gonna take some money to get there.with stock injectors the most you will get is about an extra 75HP.
