I'm sure I asked this before but can't find it with the search feature. I could use some vacuum diagrams for the l67 vs 86 fiero gt. Even better (and what i had before) was an explanation on someone's build thread that i can't seem to find anymore. Just need to know where to hook up all those wonderful little lines.

I'm also in need of 3800 vacuum diagrams. I have a 2005 series III supercharger and engine, with a 98 throttle body and wiring. Pictures or diagrams would be great, but even a written explanation of what vac hoses need to go where would help. This is the only thread that came up under search for "3800 vacuum line" in the title, so I thought it best to ask here.

I have the shop manuals. Let me check tonight when I get home and I'll try to post them up.

IVE been looking for that diagram!!! thank you for posting that!

I try to cap off the top "no-boost" vac port, and run the booster and BBV off of the evap line. The rest of the "boost" vac ports are all ran stock.

That diagram helps.. I'll have to go home to look, but I don't remember there being a vac connection on my throttle body. Maybe I overlooked it? It's a 98 TB from a GTP if I remember correctly, as is the ECM and MAP sensor.

My supercharger has a 3-way vac connection on top, one which I planned for the brake booster, one for the bypass valve, and the other? There is also a large vac fitting near where it says "to pcv valve". I didn't think there was a PCV valve on my engine? I've got a breather on one of the valve covers, thats it
