the probe can be in either location. there will be about a 300* drop through the turbo.

 

On my 06 heres's where I put mine.....



No need to take the turbo off. Like others have said go slow and don't drill in that center web area. I was like a surgon out there.....I was drilling and my buddy was running the shop vac. Suction....more suction! I used a pencil magnet to get any chips that may have been left behind. When done drilling crank the eng over a couple of burps to get any last shavings out. Then spin the turbo by hand...with the eng off!! Just to make dam sure everything is clear.

 

What is so difficult about removing the turbo to be absolutely sure?

 

Not hard, just time consuming, and IMO, more work than you need to do.

Ive done it without dropping anything on two trucks, no issues.
Like I said earlier, just keep the shavings small, take your time, the quicker you try to push that bit in there, the larger the shavings are.

The bottom line though, it all comes down to preference, if someone feels the need to drop it, go for it, its your truck, your choice.

 

When I did my 04' I just had the engine running.. Even without blocking the pipe their is a buttload of pressure in front of the turbo.. I even ran the tap with the engine running(I had to wear a heavy glove though, dang exhaust was HOT!!).

 

Yes running the shop vac while drilling is good, then I got a straw and attached it to the end of the funnel connection of the shop vac and was able to vac out inside the hole.

 

if you drop the turbo do you need a new gasket or just reattach the idea of just drilling slow still freaks me out

 

How many size drill bits did you step up from?
