Need Info on 180sx/rb25det

so i have a few questions regarding parts in my engine bay as well as a question about a vacuum hose.

a bit of info - haven't really worked on this project for 2 years, basically dropped the engine in and couldn't do much else due to money issues so I'm hazy on some things that might be simple.

 

what is this? was located next to & connected to what i think is the "vacuum regulator" in the corner of the engine bay near the brake booster.

 

 

is this the "vacuum regulator", what purpose does it serve and do i need it in my 180sx rb25det conversion?

 

 

does this pipe which reads "air intake turbo mani" just go into the intake manifold?

 

 

 

which one of these would i attach to the other or what not to turn off abs error on the dash

(I assume its the abs making the ( ! ) come on since everything else was plugged up when running the ignition.)

.

 

any help is greatly appreciated.

got some other things I would like to know.

 

what is this vacuum fitting for? if i remember right it was connected to the actuator looking thing on the intake "tunnel" in the 2nd photo.

 

 

what is this and what purpose does it serve? (the actuator looking thing) was connected to the intake pipe going into the turbo if i remember right.

 

 

 

Also if i just put a mini air filter onto the IAC valve will it work like normal or does it need to be connected to the intake piping? (don't see why the air filter idea wouldn't work fine)
