I don't think so, the TII and NA engines' bac valve are on opposite sides. Just go look at it, it'll be pretty apparent which one you need to use

I know they are on opposite sides, I was just thinking that because of the way they work the vac routing and such should be quite similar and therefore potentially both run off a vac line that feeds both rotors.

BAC valves don't run off vacuum... there's a vacuum nipple near the bac valve on TII's, but the BAC is a solenoid operated valve that allows more or less air to bypass the TB to maintain the idle. No vacuum nipples on it.

My bad, I just rechecked the pictures and I realize I misinterpreted them. I've been going off pic #32 here. I was originally thinking the vac lines in pic #28 but I do not know where they go. Now I really wish I would've studied more while I was pulling all my injectors...

One of the ones in 28 would be fine, but I'm not sure if you still have the ACV or not. I'm thinking it might use up some of those ports. Who cares though, so long as the boost sensor is plumbed to vacuum, the car will at least run. No need for all that extra emissions **** when just sitting in the driveway fogging the neighborhood.

The car is bone stock, why would it matter if I still had the ACV or not anyways? Isn't it just some emission piece of garbage? I may be wrong, but I think I faintly remember that those two lines go to the boost sensor. I'll check tomorrow when I actually have to go out in the snow and cold to go to school to be sure.

Exactly, I was just stating that your car might not look like the pictures, since the ACV takes up a considerable amount of space, and it might hide or block access to those vacuum ports.

I just went out and check it and the ACV does not block those two ports, and I was wrong about where they went, they snake around the back to a bracket that bolts to the manifold and then onto metal lines. There's a port right next to them on the manifold, in pic 35 very bottom, that runs to the boost sensor.
