I guess i'll just tap the intake manifold, i kinda need it by this weekend and it would take too long to get it shipped here and stuff.. oh well, how thick is the wall on the intake manifold? who all has done it? how do you clean out all the shavings it makes

get an Al bung and TIG it on to your IC pipe.

I wouldn't tap the intake mani, if the mani is on the motor. And it's a lot of work to remove it from the motor. Easiest thing is to pull the charge pipe at the t-body, drill, weld, and go...

.99$ bung from ACE Hardware....get a 1/2" Compression fitting sleeve.

the threading is 3/8" and the hole for the "line" is the perfect size for the sensors element to fit through.

Ok i have a question.. I'm trying to order some taps online because earlier i went to lowes and other stores and they didnt have any that i need..

Whats the difference between a NPT tap and a NC tap.. the reason i ask is i found a 3/8" NC tap at lowes but it was tiny compared to the 9/16" drill bit im supposed to use, so i'm guessing they use a different way to measure it?

Autoparts stores carry NPT taps individually pretty commonly.
The NC tap is not close to a NPT tap. The NPT taps are larger than what you sould assume they are and they are tapered for a compression fit when tightening.

Harbor Freight had a tap kit on clearance in their last ad. Go there, if there's one close.

nc = national coarse thread
npt = national pipe thread

pipe thread is based on pipe size which doesn't really correspond to the outside diameter of the pipe...

and it's tapered.

when you find the right one, it will most likely just say 3/8" or 3/8-16 or something, NC is not NPT.

I would do the intake pipe due to known heat soak issues with intake manifolds.

For my intallation with a picture in page 1 of this thread, I removed the manifold and would not consider doing it any other way. For me it was pretty much an easy task, but it takes some time ... maybe a few hours. I painted it black at the same time.
