Im in the process of gathering parts to convert my 87 turbo t to hydroboost. Ive seen the astro van conversions, but ive stumbled upon a unit off an 80s b body GM that looks extremely similar to one off a hot air turbo g body. I picked up the b body unit and ive sourced a g body diesel unit from a junkyard and im waiting for it to be shipped. I will do a side by side of them when i get ready to convert. the only difference i can tell in the b body unit is it sits about half an inch taller in the mounting plate than a gbody unit. Has anyone tried this before??
