If you keep the oil return, you only need to worry about oil feed. This connects under the exhaust manifold. The hardest part is attaching the fitting and line to the turbo, this is where taking the turbo/mani out of the car will help. One of the coolant lines also attaches right under the exhaust manifold. The other hardline runs behind the head (secured to the head with 2 12mm bolts, also note this hardline will prove difficult to remove with head on. I would say possible though, bolts are threaded into the back of the head parallel to the cams) then to a rubber coolant hose at the back of the upper intake mani like J mentioned.
Loosening and tightening these mf'ing 19mm banjo bolts with the turbo on is a mf'ing pita pos job. i f'ing hated it. it's a jigsaw puzzle seriously. This is what i did on my last job in there. Bought a hydraulic hose and fittings according to the_chosen_ones thread. Upon removal, i cut the **** out of my water hard lines with a dremel, i was done with those 19mm banjos. pulled the turbo out. installed fitting / line to turbo and block. Bought a pack of 5 M14x1.5 oil drain bolts. With crush washers i blocked off the water connection on exhaust side of engine. Completely removed the hardline from the head and the rubber line from the mani. Welded shut the coolant tube under the intake mani that feeds the back of the intake mani and thus the turbo. I also put 2 of my M14x1.5 bolts in the turbo to keep debris out. I cut a notch in one so expanding air can escape.
I am on an SR T25 and there is information and debate regarding both sides of running water lines or not. To me, I'll take the chance of listening to people who say its ok so that i never have to use those 19mm banjo bolts again. Anyways, i'd rather pay 125 for a new turbo than deal with those banjo bolts. Also, now it is cake to remove / install turbo (aside from the ehxuast stud/nut location).
The other plus is this line upgrade cost me the line ($15 hydraulic shop) and 2 fittings found online (ref. TCO thread, cost $20 for both shipped). So $35 and I'm done. I have dimensions for my line that works perfectly for stock mani / T25. My original was close to TCO's length (11 inch iirc, or 9 inch?) and it had to twist in a loop to fit. I will provide dimensions when i get home. good luck!
