There is quite a bit or things out of the ordinary on your car.
Pictures 1-3: Where's the rust? :lol:
Picture 4: Looks like you have a boost gauge. How much boost are you running?
Picture 5: Looks like a bleed off valve, but I could easily be wrong
Picture 6: The plug on the hose is a little heater, it's hanging by the fuel hoses that you have pictured later on
Picture 7: Looks like you are missing a bolt on the downpipe
Picture 8: There is suppose to be a vacuum hose that hooked up under where the duct tape is. Most likely to control your fast idle
Picture 9: Throttle cable hooks in there (I think)
Picture 10: That's the heater wire I was talking about earlier
Picture 11: No idea, can you get a better picture? Is it hooked up?
Picture 12: Is that vacuum hose just laying there open?
Picutre 13: looks normal
Picture 14: I belieive that is the fast idle control
Picture 15: Your pump is missing some pieces. There is a switch twist tied to the throttle cable, it's suppose to be ontop of the pump on the left side. You are also suppose to see a vacuum pod on the top of the pump. If you look on the back of the pump, do you see a rod conencting to levers?
Picture 16: Looks like a custom drain line
Picture 17: Can't tell
You don't have an EGR, and if you didn't swap intake manifolds you never had one.
