only ones that were turbo were the 1980 models.

 

I just picked up a sd33 from a CJ10A , its a from a US military tug , the sd33t is the turbo version and the sd33 is non turbo , check out
Binder Planet Forums
for more info on the sd33t . Mine has a tf727 that has the jeep NP/NV 23 spline output shaft ,( its going into a comanche) it is an industrial motor , designed to run forever , not a huge power house from the factory , but parts are still plenty . in auz and nz there are loads of them in nissan patrols . and for those who think you cant make power with these lookie here
the ones like i have ( from the military) are heavy duty versions just without a turbo .

 

Two intercoolers for 9psi of boost? You're just restricting flow with that first one.
