Well, I got my ebay ATS turbo the other day. I pulled the ATS from the truck, took a good look at everything, noticed I had VERY little side play, and no end play on my center section or cartridge, whatever you want to call it. I disassembled the ebay unit, took the compressor wheel off, installed it on my old unit. I did this by making a slight mark on the turbine side before disassembling things, noting where the compressor was balanced. The compressor wheels were very closely balanced (according to appearance, the removal of materials, etc). I installed the wheel into my old stuff, reinstalled it, and everything in that respect works peachy. I actually make boost before 3000 rpm now. Naturally, it wasn't all peaches and cream, because I must have nailed the oil pressure sending unit with something, because now it jumps the needle like something off of a lie detector machine, and I keep getting an engine light. Any other places you can plumb a mechanical oil pressure gauge in other than under that damn turbo? Is it safe to run a Tee fitting at the turbocharger oil inlet, and run a pressure gauge from there?

Reason: Adding another question LOL.

Well, that is where the factory turbos have the sender.
or you could tap into the block down above the oil filter just aft of it, there is a very small square plug head sticking out you can tap a 1/8 npt fitting in there, but you will need a special 9/32 pipe plug socket to get that square plug out without rounding it out( snap on sells one)

I'll check into the one near the filter, I may already have the proper socket. But, if it's safe to do, and apparently it is, I'll go ahead and plumb a tee fitting to the turbo oil inlet. Thanks for the information!

Hope I didn't do anything bad. I know it's not the most professional looking job out there, but NOBODY had a compatible Tee fitting in my area; so it was off to the hardware store, and here's the result. Also; I've heard somewhere (Maybe Dave S, not sure) that these 6.9s are safe down to about 3psi; but, ideally, what do you think I should push at that location, cold, running 15-40 dino oil that definitely needs changed?

Honestly, I like what you did, because its a real pain to get in behind the turbo to get at the fittings. As for the hardware store fittings you used, I see no problem with them. Did you keep the original fitting to the entrance of the port on the turbocharger? That is supposed to work as an orifice tube.

Thanks. I was not taking things apart again just to get to the original location, so this was a viable option. I kept the original "L" fitting, although because of the way the parts fit together, it ended up right where you see the braided line terminate, so it's feeding the oil through the original fitting. I used one 1/4" brass 90D "Street Elbow", one 1/4" brass "Tee", and one 1/4"x1.5" Brass "Pipe Nipple". $12.69 total in parts, outside of the oil pressure gauge itself.
