I am about to do the EGT Probe install on the truck. My question is I need to know what is a good gasket for the turbo and down pipe? I am going to remove the turbo to do the drilling and tapping on the manifold. I want a good gasket and is there anything I need to look out for or tips while I do this install. I got the probe from vulcanperformance and it came with a green box ( I am assuming a amplifier?).

 

Thanks in advance 

You sure you want to go through all that hassle to drill the hole? Many people drill the hole without removing it just fine and have nary a problem doing so...

I wouldn't and have not ever removed a turbo when drilling and tapping in a probe. If anything does fall in it is so small it will puff through the turbo into the exhaust long before it starts to spin. I just set a magnet tip next to the hole while I am drilling and tapping to pull the cuttings away as I am doing it and have never had an issue.

Hmm I am so afraid of trashing the turbo. Any advice where on the manifold I need to tap? 

Right where they converge to one.

Dead center of the top of the hump of the rear section of the outlet just before the turbo to manifold joint.

This should help:

When I did my egt probe I use grease on drill bit a nd tap as well as magnet. If you have a small pencil mag. you can fish around the hole as extra. Did mine 2 yr ago following above link no problem. 

Thanks, I'll just do that instead:)

You could drill it out while the engine is running then the pressure of the exhaust blows the chips back out and the twist of the pull the chips up as well.

Drill it out with shop vac going. Use magnet to probe interior for chips. You will be good to go. Gauges are a real eye opener and the greatest asset when monitoring the performance of these trucks. Have fun.

Very good ideas!! This will make the install much easier!
