I'm getting ready to install a set of gauges soon and I've been trying to get a game plan as to not have any hang ups when it's time. My question is would it not be better to install the thermocouple on top of the drivers side manifold instead of coming up from the bottom? To me it looks just as easy or easier.
Another thought is if you have the EBPV delete why not use the hole where the tube connects to the manifold for the thermocouple or is it not the right size. May be able to get a bushing to fit or drill the hole out to the size needed. Just my thoughts. Any input anyone.
Well i ran mine up from the bottom and it wasn't that difficult. As far as putting it in the ebpv, i think thats after the turbo. So your not getting the most accurate reading unless its before the turbo. Isspro sells 2 different pyros, one for pre and one for post turbo. Most go in pre turbo though. Heres a link if you need help. DieselManor - Installation Sheets

The EBPV tube fitting is mounted in the manifold which is pre turbo.
As far as going topside with the probe hole. You are drilling into cast iron. If you put a lot of force behind the drill you might be able to get some shavings, but if you let a good sharp bit do the cutting with slight pressure you will get more dust or powdered type look to the so called "chips". Which should pass right through the turbo with no problem. IMO
I installed mine on top of the driverside manifold. I have had zero problems and the turbo looks good as far as any damage from shavings or filings from the drilling. Use some axle grease on the bit and the tap. Then take a shop vac to the hole you just drilled and tapped.
It really isn't the drilling that will put the shavings or filings into the exhaust it is the tapping.
