As ive mentioned in previous threads, ive not worked with turbos in many many years and my knowledge is limited. I have an 87 TC, currently the only mod is that i have a K&N Cone filter installed and the airbox is gone.
I'm reading the instructions on here as well as that came with the gillis valve and before i go and mess it all up i wanted to write up what i *think* i should be doing. Please let me know if i have something backwards. I may be the only person in history to ever install a mass airflow sensor backwards on a 94 probe.
Vacuum tube will be cut to length,
The valve seems self explanatory. Inlet to the vacuum tree (have an unused port capped off, will uncap and hook up hose)
Outlet will vacuum tube hook to the Waste gate, the vacuum hose that is on the angled vacuum port.
I did not get a hex plug, but i did get a square NPT plug in my kit. I assume it works the same. This goes to the compressor outlet where the 2 port fitting used to be. (i assume i just save this fitting in case i go back to stock?)
the vacuum port cap, i assume that goes to the compressor inlet port
The straight line vac hose connector goes on the hose that runs from the wastegate to where the 2 port fitting was. I essentially pull the hose off from the 2 port fitting and put the connector on it, which then i connect the new vacuum hose that runs directly to the gillis valve outlet.
OK now to question time;
zip ties, am i supposed to use the zip ties as a hose clamp? I assume i should supply my own hose clamps and these are used for holding the hoses in place.
The hoses from the BCS, if i read right i should just secure them somewhere and leave them?
Last question, it was dark when i did the K&N Swap and just remembered something. I won't get to tinker with the TC until sunday but when i swapped out the airbox, The elbow coming out of the VAM that ran to the airbox was removed and in the elbow there was a small air hose on the bottom that ran to a box under my bumper... What is this box? I feel silly for having to ask, but i have no idea and couldn't get a good look at it in the dark (as i was doing the cone to VAM setup, it got completely dark and started a downpour).
