Several members highly recommend the probe from aircraftspruce.com Surprisingly inexpensive considering the praise it gets. I haven't tried one myself, but I think the next one I need, I will try one.As for the location, you want to put in the manifold just before turbo, like so:There's a small flat spot on the bottom that works nicely.
I imagine you can drill it out in the car, sure. If I remember correctly there should be enough room to stick a drill between the downpipe and oil drain line, and of course the axle (though you may have to remove the axle, I really dunno for sure). I would be more worried about the tapping / welding. I welded a special hollow bolt on for mine, which I suppose could be done without removing the mani, but if you're going to tap it manually, I would be worried about clearance of the tap handle around the downpipe and oil drain line, and keeping it all straight. Using a drill to tap shouldn't be an issue, if you got it drilled in the first place.

What do you think is less work? Pulling the axle (have not done it before) and drill and tap from below? or pull inlet manifold and turbo/ exhaust manifold and drill and tap on the bench? I have done a head gasket job last summer so should not have any rusted nuts and bolts issues. Should have drilled ad tapped it when the head was off but I was in a rush to get the job done and forgot about it.
on the td engine I'm freshing up on the engine stand right now I want to drill and tap it while its easy and just put a bolt in it until I have the extra money for the guage. what size tap should I use?
aircraft spruce micro 1000 all the way
pass axle is CAKE to remove. dont even have to separate the ball joint from the a-arm.. just comes out..BE 100% sure to torque the BIG AXLE NUT to ~190 ft lbs..if you dont torque the nut enough, or torque it too tight, it will mess up your wheel bearing.
