Default Ludespeed specific questions

I just thought I would throw this out there since it's been bugging me for a few days. My ludespeed kit which I bought used has an intake pipe (the one made by ludespeed) with two holes in it. One hole has a barb fitting in it to accept a 1/2" hose (I think) that is teed into the valve breathers and pcv valve hoses. What could the second hole in the intake pipe be for?

BTW: I think this kit might have been made with the 98 RS in mind, but I don't see what that would matter.

One other thing about my kit that confuses me. AFAIK, the kit is suppose to come with two 5/8" brass tees which are used to run coolant to and from the turbo. My kit has 4 of these fittings and they all appeared to have been used before, which confuses me. Besides the coolant lines, is there something else this big that needs to be teed?

The two holes were both likely for the PCV system. Originally the intake pipes had 3 taps on them, but some people had to trim them down (like with mine) in order to get the filter pipes to not hit the head. I had mine plugged anyways because I was using a catch can. A fitting in one/both would serve as a good source of vaccum for a more complicated PCV setup, though.

You only need two of those coolant tees. I hadn't been able to find the tees that they used anywhere else, so keep those two extra just in case.

the return line for the BOV would be really small judging from the nipple size on the BOV... and the hole in the intake pipe accepts a 3/8 npt fitting, probably suitable for some kind of 1/2 or 5/8 hose which is a lot bigger.

So, I guess both holes in the intake pipe are for the pcv system/valve breathers. As far as the ludespeed instructions go, he has both of the valve breather hoses and the PCV line being tee'ed into a single hole in the intake pipe, which is why the second hole confused me. Maybe I have newer instructions and an older pipe.

I was thinking about using a catch can, but am not sure if I should route the breather hoses and pcv hose to the catch can then back into the intake, or just let the can vent to the atmosphere. There seems to be debate about this. I'm guessing if I did this, I could just plug up both of the holes in my intake pipe?

It just occured to me that the extra 2 brass Tees in my kit were probably used for the breather hoses.
