Used tubos for free, couple questions.
There are a couple junk turbo diesel motors at work. The boss said that if I can get the turbos off by Friday they are mine. I know for a fact that one motor threw a rod through the block and the other had a blown head gasket that was not attended to and it seized. The turbos appear to be in the 70-80 mm range. They also spin freely.
How do I check the turbos to see if they are usable?
Does it matter that the turbo came off a diesel? A turbo is a turbo, right?

Most diesel turbos are low pressure turbos. Dodge uses Holsets, and while they are good units, simply pulling some off and slapping them on a V8 won't work. Well, it would, but you'd put an awful lot of effort in for about 30hp. You'd have to rev the snot out of it to make any sort of usable boost.
They work well on small, high revving motors...like imports. But don't do so well on slow turning V8's.
One might make a good start to a progressive TT setup by stacking a normal high pressure turbo on to one of those big low pressure units to spin it up faster....
But, free is free...and there's bound to be SOMEbody that could/would use them.

These are Garrett turbos, the motors are both Mitsubishi inline 6 cylinders, roughly the size of a 5.9 Cummins if that matters. I know there are thousands of turbo variants out there, my is a turbo a turbo question was more geared to will it work at all.
I was figuring that if these turbos made boost from a 6 cylinder diesel at 2,000 rpms, a v8 at 6,000 rpms should be able to spool it nicely. I was also thinking that these turbos would have low boost but move lots of air compared to many turbos due to the fact that diesels have very high compression.
My plan is to add one to a 6.0 and work for 500 WHP, which should only be what, 8-10 lbs?

I am not exactly sure on displacement, but it is physically about the same size as a 5.9 Cummins. It is probably about 6-7 liters. I have been unable to find specs on the motor. I am working on it though, because if I can figure out how much boost it makes at a certain RPM, I can see if I am wasting time or not.

I used a diesel turbo from an older Ford F6000 cab over with a 6 liter or so Ford diesel inline 6 to power a 5.0 that I transplanted into a BMW E30. Long story short, the turbo spooled full song at around 1800 or so rpm, made over 600 ft lbs and 400hp at the wheels, but was done by 4000 to 4200 rpm. A very short but impressive powerband, determined by the small turbine side of the turbo.
Upgrading the turbo was a pain because of the limited space in the compartment everything had to be changed. Lesson learned, make sure the turbo is the right size for the application.

i kno 5.9 cummins hx30/35 one of them are too small for a v-8..def run outa steam.. but two of may work.. and you said that motor is roufly the same size as a 5.9 cummins.. just saying..you can get a diseal turbo to work.. but there are a lot of varibles.. im no expert..just did a lot of googling about making them work..seams better just to buy right turbo..

Lots of info here... If I were to use both would they still run out of steam? Seems like it would be more like 4K rpms to get on boost that way. How does boost apply with two turbos? If I am getting 5 lbs on both sides, does it make 10 lbs?

After some quick lunch reading i found some info for you. The motors seem to be either a 4d55 or a 4d56 used in 83-85 Mitsubishi Pickups and Dodge Ram 50, but you said it was an i6 so im not sure.
If it is either of those two motors the turbos could be either a TC05 or TD04-09. I've heard of the upgraded version of the td04 used as upgrades in wrx's i think. Might be small for an ls motor but hey its free give it a try.

They sound really small... My experience says that anything used on a sub 7.0L diesel will typically struggle to make more than 400whp on a gas motor with the exception of some of the newest of the new truck turbos.
Get some measurements, and it will be clear what they are able to flow. If the inducer of the compressor wheel is less than 56mm.... You probably are just better off throwing them out, or trying to fit both of them on your car.

Well, looks like my luck ran out... The shafts in both turbos have play. The turbine on either side can wobble about 1/16" to where it is almost rubbing against the housing. With the cost to rebuild even one I could just buy a new one surely.
These turbos probably have 15,000 hours on them anyways, 10 hours a day, 6 days a week for 10+ years. @ Marcello7x, these motors weigh in at about 1100 lbs, I don't see them in anything less than an industrial truck in that day and age. The 4D motors are 4 cylinders... and they were in 1 ton commercial trucks
