Hi guys, I am trying to help a buddy of mine put his engine back together. I think he had the head rebuilt. The throttle body was separated, and now I am trying to figure out where vacuum lines go. Please help me find out where things are supposed to be connected. He needs this car running in 2 weeks.
The 2 hard lines in the bottom left by the pulley and the hard line to the left of the throttle body in the picture. It seems to lead to the head.

The 2 openings on the blowoff valve toward the bottom of the picture.

Opening on the wastegate.

I don't know where this black box goes or what it does.


These lines seem to have some sort of valve in the middle.

Any help would be appreciated. Thanks guys.

In the first pic. The large one goes underneath the throttle body on the intake manifold.

The two small ones on the left side of the pic is where the line with the valve in the middle connect. (should be able to find a diagram on here somewhere of the layout of those)

As for the blowoff valve and the wastegate, most people purchase a vacuum block and tap into a large single vacuum supply off the intake manifold and plug all the small ones into the vacuum block. They just need a good source of vacuum is all.

Ok, thanks 4forall. Does anyone know if the black box in pictures 4 and 5 is the vacuum box? It looks similar to the vacuum tank in the service manual.

yes it is the vacuume box, it bolts to the back side of the front cross section of the frame where the stock air box sits on top of.
