I rebuilt my engine, to my own stupidity (noob) I did not mark or take pictures of my progress so i can refenrece theem when putting everything back together. I took a wild guess on a lot of them considering the diagrams ive searched on here had barely anything to do with what my stock setup looks like. All of the actuators in the back are good, that was the only helpful thing on the diagram. The rest do not make sense. I have an 04 manual High power if that makes a difference. The picture below shows the hose im having the most difficult time with, its on the bottom of the throttle body and has some rust on it, my guess is, water ran through it, but my common sense tells me no water goes through a throttle body. Please help. Or if someone has an rx8 in the tampa bay area, can we meet so I can look at your stock car to see where they go?

 

That hose is the vacuum to switch the intake tract length.

Runs from the TB to a solenoid under the airbox, to a metal pipe running to an actuator in front of the airbox.

If I recall.....

 

Uh, yeah that's the throttle body coolant hose. Coolant goes from a nipple at the front of the thermostat housing, to the throttle body, and then goes to a nipple on the passenger side rear engine iron. If you had forgotten it you would have had a huge mess on your hands.
