No, the OBS ford 7.3's do not have wastegated turbo's
Would love to find proof to help you out, but honestly its not even worth the time to look for solid proof. It says it all over the internet, its a big difference between the old 7.3s and the new ones....so is an intercooler, and PMR's

Tell you friend to find the wastegate on your turbo...problem solved, and when he cant tell him he is wrong.

if your friend wants to argue bout it, pop your hood and show him, its pretty obvious when you look at an obs vs an SD

ive said that, they tell me its internal and we wouldnt be able to see it. needless to say, im not gonna tear apart my turbo to settle a dumb argument. maybe a nice fat bet though....

So if they are so smart....how does the 'internal' wastegate operate with no outside linkage???
And.....how come my turbo will explode if I dont take it easy.....thats right cuz it will blow up from the psi with no wastegate to control it

You dont have any hp mods done, yours is fine, but I could blow mine up.

No a d66 is not. But it will hold 40 psi, constantly above that will blow it up

A d66 is built from our stock turbo and looks exactly the same
