dslsmoke, who won't tell us any details.
OK!,
You twisted my arm
, I don't really have a lot of time (I'm at work now
) so I will, for now copy some of my old posts on another forum and paste them here, even if just to wet your appetite
....
You can, just go to your local recycling yard and look for a '81 thru '84 Nissan 280Z Turbo, remove the exhaust manifold, turbo, down pipe, inlet hoses, clamps discharge pipe and don't forget the elbow to attach the discharge pipe to your intake manifold.(make sure you get the oil feed and return lines to and from the turbo)
Then you go to the auto parts store and buy an intake/exhaust gasket for the Diesel. (NOT THE L28 GAS ENGINE)
The mounting flange for the new exhaust manifold will require some minor work, nothing a good bench grinder can't take care of!
The down pipe will interfere with the steering knuckle, you will have to cut about 3" just after the O2 sensor and weld it back (pay close attention to the angle in which you weld it) as for the flange might get in the way of the steering.
As far as the oil supply and return are concerned, just tap into the oil feed and return for the vacuum pump at the alternator.
Go to you muffler shop and have a 2½" or 3" system built for you (NO MUFFLER, YOU DON'T NEED IT WITH THIS SETUP) and get ready for some sweet sounds. One more benefit you'll get from this will be reduced smoke out the tail pipe and of course you will feel an extra "PUNCH" in the seat of you pants when you press the loud pedal.
Here are the instruments I use..
The turbos in my cars have factory waste gates set up for 7.5# of boost, I have taken them up there several times but not for a very long time as I am concerned about the EGT's.
When pulling hard, like up hill at WOT, the EGT's can go up very fast and you don't really want to have them up too high. The higher I've had them it's been 980° F under these conditions.(before the BBQ gas). At normal cruise however, they usually hover around 550° F to 650°F of course the pyro gauge is located after the turbo where the o2 sensor goes in the gas engine

Here to read some of the details, if you want more info,,
I hope this old info can help you, I did this swap so long ago, that I have missed placed the pictures, and it is difficult to get new ones now that both my sons have basically taken over the cars as if they owned them, Imagen that!!!!!!

, something very very interesting indeed 
) I've thought about it more than a few times that's for sure, but considering the mileage I've accumulated already I'd probably prefer to rebuild an engine first and do it as a whole project. I actually am more interested in turbocharging an SD25 diesel to put into a project 720, but there are no exhaust manifolds out there that you can almost bolt up to one (like an LD28). Al, that sure will be cool to see you go ahead and do it. It will be a learning process for most of us here I'm sure.
Oh and will an SD22 forklift manifold bolt up to an SD25 engine? Will an SD22 intake manifold bolt up to an SD25? Thanks.
