Where to drill for EGT and Boost fittings?

[Texas Diesel]

Any suggestions?

There are alot of threads on both subjects, go back and take a look.

For boost, Remove and drill and tap the intake pipe. Its easy to get to and you wont need any special fittings, just order a spare gasket for when you bolt the pipe back on.



For the Thermocouple for the EGT gauge, drill and tap the exhaust manifold before the turbo, DO NOT drill in the "Valley" drill in the middle of one of the tubes. Just go easy and use lots of grease to control the fillings. Then a shop vac and a magnet will help clean up any you missed. SOme people remove the turbo to do this, its not really nessecary, just do a good cleanup. At startup, any small fillings you missed will be blown out the exhaust with no harm.



I am going outside right now to take pics of both and will put them up here, give me a few minutes.

Here is the Thermocouple Location. Pre Turbo.

And here is the boost fitting location. You can see the brass fitting in the center of the intake pipe.

Thanks EM!!! We'll be drilling in a few minutes, good tip about not removing turbo too. I like where you placed your thermocouple as well.

I am about 80% sure that I read a post by TST several weeks ago and he told someone to drill and place the pyro probe post turbo. Am I wrong about that?

All done. Boost = 20 PSI with OEM elbow and 28 PSI with wastegate disabled. I think I'll leave the clamp on the waste gate line intill I can figure a way to install the EZ elbow. (warranty concerne here) Fuel pressure gauge still on backorder.

Every time i have spoken to TST they have always said PRE Turbo for the Thermocouple.
