Well the way i look at it is , better headers, better intake, turbo is out of the way , looks better , you can get alot of chrome for this set up unlike the 84-85 motors, looks eazy to work on. I think thats it.
Ok , pass header , upper and lower intake , tb , is there a backet that holds the alt that i would need off the 87. is the fuel rail the same or no 85-87 .and move the coil and a little rewire job , is this about it guys.
