pi intake

[96SCstang]

alright, i know there alot of post about pi intake swaps on npi cars, but i couldnt find the exact answers to my questions, so plz help me out again. I know i need to drill and tap another sensor hole for my two temp sensors, but how safe is it to do that, because there is no bung there and is seems like pretty thin aluminum. or is there another way? also i know you guys have used silicone around the coolant passages but what gaskets are you using(npi or pi)? Also are u just putting silicone around the passage and that is it or is there something special i need to do. Any tricks would be very helpful and appreciated. i only want to do this once so i want to do it right. thank you :SNSign:

See my sig for links to my writeup as well as links to other peoples writeups.
I just had a local shop tap it for me since I have bad luck with stuff and this was one thing I didn't want to screw up. It should be fairly simple to tap the port though...Circled area in the picture is where you tap the new hole.

It doesn't really matter what gasket you use as either one requires some reinforcement with RTV(black). NPI requires RTV around the air ports and PI gaskets require RTV around the coolant passage. Supposedly PI gaskets allow better airflow, I went with NPI gaskets.

if you are afraid to drill/tap your crossover you could have a local machine shop do it for you.
