Im currently working on polishing my HO manifold
I was wondering what something did on it and do i need it for my Twin Cam?
I shaved off all the tabs and casting lines and just wanna know about this thing with the arrow and circle My manifold just came as a empty hole
Thanks
yes its unused unless you want to run your pcv hose to it.

That would be too much vacuum, with out an oil to air separator....... and I still think it would to much.

One more question
I have the Vibrant Performace intake but when i cut it to tit my HO mani ill have to move the hose that runs to it which i believe is the PCV hose
Anyone have a solution for this?
I can take a pic of the hose im talking about if needed Thanks
put a breather filter on the end

You know you have to block off your EGR too right?
My cavy is a 2000 i dont have a EGR
Put a breather on the end of the PCV tube?

yes
For your first question, I have a seperate fitting in that hole which I have plumbed to my MAP sensor. Or you could just plug it like the others suggested.

Another question
Do you know if you can buy one of those hole filler things thats at the far right of my picture?
Looks like its screwed in with a Hex or Allen key id like to get one to fill the hole where i took the sensor out on top of the manifold cause i dont need it
That large pipe on the rear, I ran Brake booster hoses to that (on mine it has the smaller fitting, so I used it for my MAP sensor). Or you can pick up a cover for it.
Large hole in the top (MAT Sensor hole) You can either use the 2.3 MAT (think IAT) sensor, and not use the one in the intake tube, or go to a hardware store and get the correct size pipe plug for it.
NEVER run your Air/Oil seperator hose to the intake manifold!!!

Or Does anyone have a good pic of your installs

Darren, I sent you this pic I thought. It shows most of the connections and where they end up.
just so i dont start a new thread:
i understand it goes
yellow -> fuel rail
red-> map sensor
but for the white, i know the f-body iat sensor should go in this hole or am i mistaken?
and
the circled nipple here can be blocked off or a breather filter goes on here
also...
in this same pic you can see the allen key pipe plug, can this be used at all?
Clears up alot of things for me
What do most of you do with the hose that runs into your intakes?
I know my intake came with a longer piece of tube to extend far enough but ill be cutting it now where it plugs in
Thanks

Breather filter = vacuum leak

"Youth in Asia"...I don't see anything wrong with that.
can you use the stock t/b bracket with the ho mani.? Does anything have to be done to it and as well as the cables?
I used the stock bracket. I used a 2.4 tb and bracket and all i did was run the cables under the lip of the battery tray.
No i mean an after market WAI
You run a large rubber hose to it i think its the crankcase vent line
Do you guys just drill a new hole in your intakes and attach something?

Yup
But I had a problem with unecessary amounts of oil collecting in the TB and manifold... so I said F*** that and bought a K&N crankcase filter.
