Well I've added a fmic and I need help with some vacum just to double check if i got everything right.
This is for reference i found it at zerothread?id=305170.
Well i bought the car already swapped so it look like i'm missing the EAI control valve, the EAI control solenoid and the boost pressure solenoid because i did not have any of those lines running like that.
Now lets look at the first pic :roll: Now is this right if i have the line from the wastegate go to the line beside throttle body. Is this how you hook up a BOV?
Is it alright if i plug this one up, my friends 180's is plugged up.
Now i think this is the reciculatory system i dont think i'll keep it because it will just add more vacum line headaches. Can i put my bov at this spot? If not what's the best way to cap it off?
Now for the finale!Since i won't be using the recirculation valve i can just cap that hole off, what's the easiest way?
Thanks for your patience,!!Alex

The wastegate gets its vacuum from the cold or hot intercooler pipe, not from the throttle body unless its forward of the throttle plate.
The BOV gets its vacuum from the throttle body.
The line you are holding in the second pic is the return from the charcoal canister. You do not have the charcoal canister anymore so just cap that. It runs to the gas tank.
You can just leave the BOV where its at if you dont have a mount for the intercooler pipe down by the ricirc valve. Cap both the hole in the intake pipe and hot pipe where the recirc used to be. Places like hardware stores sell caps, I just used to be ghetto and use gatorade bottle caps, electrical and duct tape, and hose clamps back in the day. Just remember that the intercooler cap will have pressure placed on it so it needs to be fastened properly.

I've been running my wastegate off a throttle body line since 2004 with no ill effects. I use one vac line to run my bypass valve, wastegate, and I use it for my boost gauge line as well. The other TB nipple on top goes to my FPR, and the bottom gets capped off.
About the only problem that can arise from running the wastegate off the TB vac nipple is that you have a vac source that's after the pressure drop in the intercooler. Keeping that in mind, you just have to remember to set your wastegate to open a little lower than you would expect. (mine's set at 12 because of this)

Many people run the wastegate off the throttle body, its just suppose to better for the waste to get its vacuum from as close to the turbo as possible. So the BOV should work the way it is. If you want though, you could drill and semi tap a hose barb onto your IC pipe and use it as the vacuum source for the WG.
