Okay, so I got my y8 IM sitting on my living room waiting to be on my car. I'm running obd1 in my 90 Std Hatch, but I have three questions:

Pic 1, Where does this nipple on the back of the mani go? can i plug it? do I tee it somewhere?
Pic 2, I know one of these needs to be plugged. How do I plug it and still make it look good?

And 3, Where's a good place to put the iat sensor or whatever is called. I know you can put it on the intake pipping but I rather not cuz I'll be switching my intake when I get my turbo setup complete and i wanna sell the one i have on now. Where else is a good place for it?

keep the Z6 intake manifold, your gonna LOOSE power going to the Y8 intake.

In high RPM's yeah but i'm mainly going for torque so the bigger plentum and smaller runners would help he in that aspect, would it not?
