What is the best way to install the pyro probe. Do you really have to unhook the turbo to keep from getting shavings into it. I'm installing ISSPRO guages and what size drill bit do i need.

 

Start the engine and put a restriction in the end of the tailpipe, ye ol' potato in the exhaust trick. Put some grease on the drill bit and that will help catch the drill cuttings. I presume you are installing an 1/4" NPT fitting so the tap will be 1/4 X 18 NPT requiring a 7/16 drill bit see link: http://ww2.mne.ksu.edu/classes/ME300...20tapdrill.htm . Good luck!

RJ,

First, please fill out your profile so we know what you're driving...

I installed ISSPRO gauges, including a pre-turbo pyro on my 2005 w/o removing the turbo. If you do a search you'll find TONS of info on this subject. That's is how I made the decision on how to do my install.

Very simply, I used heavy bearing grease on the end of a drill bit and drilled VERY slowly, stopping to remove the chips collected in the grease frequently. After cleaning the drill bit, re-grease and go a little further. I started with a small bit and then moved up to the size required for the tap. The drill and tap size depends on the sensor you have, so check your sensor first.

As soon as the drill bit breaks through the casting, pull it out gently then use a magnet on a stick to pick up the chips inside the manifold. Keep probing around inside until it comes up CLEAN. Lot's of guys have done it this way with good success. I did mine at 500 miles and now have 18000 trouble free miles on it.

When you tap it follow the same procedure, put grease on the tap to capture the chips. Stop frequently to clean the tap off and re-grease. It will take a while but it's worth doing right the first time.

Here's a link to my pictures, including the sensor placement and gauge install.

here is another thread that i started a couple weeks ago when i was doing my install. i didn't remove my turbo i just started drilling it and when it got close i turn on the engine and drilled with it running it blew the metal shavings out. just make sure to wear some safety glasses. what year truck you have and i might be able to give you a little more info on a easier way to do it.

 

Well i just finished the install. Not as bad as i thought.Just nerve racking. Still have to install boost fitting. Diesel manor forgot to send boost bolt. It is now in the mail.

 

I drilled mine, then got an extendable magnet and got all that I could... then called it good

 

this works good
