Ok, now i have a feeling your New to you turbo that is the 13c off of the Volvo has 4 holes, one top one bottom, and one on each side, correct?
Unfortunately you picked up a water cooled turbo, and as such need the fittings from a Volvo and the piping from a early 90's 740,760,780, or 940 or 960 turbo, OR you can spend more and buy SS lines and some rather large and I'm sure not common fittings.
That turbo is limited because of the cold side being rather small and the actual ability of the turbo not being able to exceed ~18psi before it cannot physically spool any faster. I honestly would tell you to go back to the junkyard and get a T3 off of the earlier Volvo's with a .47 hot side, and you will be set as its oil cooled, and has more cfm's as well as can produce more power higher up in the curve...... just my 2 cents....
But if you want to keep that turbo, you will need water lines for it, and splice into your radiator hoses as well, as it runs with the coolant to the car.
Also let me add, that pipe you are holding on to the turbo with in those pictures is in fact the water line, one of two. those are suppose to be on the sides and then the oil feeds top and is gravity bottom. So you need both oil lines, plus the other water line...... Seriously, go back to the junkyard, get a T3 with its 2 oil lines cut off, and then go from there...... i would NOT mess with my coolant lines for some crap JY turbo if you have an option not too.
Check Turbo bricks for prices on T3 from the Volvo's, Also the Hot side should be smaller and the cold side be bigger. IIRC the cold side isnt that much bigger than the hot side, putting a bigger hot side on it would make it spool slower, and still be restricted by the cold sides stock size, as its a bitch compared to the T3.
Get a Used T3 oil cooled
