Now I wish I made photos of my 77 wagon that I stuffed a turbo efi 2.3 into, you can use the stock compressor, and brackets , (V belt ) and the stock power steering , along with the fan, shroud and radiator , they made two types of expansion valves on 74 up pintos, one was a throttle valve and the other was a block type, the older one gave more room, I also took the exhaust manifold off the engine and stuck it on my Bridgeport and milled a inch off the flange and a slight angle , moved the turbo outlet over an inch away from the expansion valve and Made up the pluming to hook up the vam to the turbo then vam to the air cleaner , the air cleaner sits on top of the vam hooked by a U shaped tube from a 84 300SD MB , the tubing from the turbo I got off cars at a wrecking yard, the stock compressor works great on 134 , you only have to dump out the old oil and use the 134 oil for newer compressors. Mine was done over eight years ago and you do not have to run it on high on hot days, later guys, I will look in my box of photos to make sure if I have any to help, 🚀
