Re:how much more oil...for turbo?
youre not going to need more than the OEM recommended 3.5-3.8L, as long as you have oil pressure and your feed line is connected properly your turbo will be getting the oil, possibly even to much
I think that filling it with to much oil and going upto or over your oil return line can cause some major problems as well
You should check your oil level a lot more than often though

yeah...it would be important to have AN OP guage...and also...if you start seeing smoke...get a restrictor valve or something close to it. Too much oil will eventually break the seals on the turbo and smoke will not be the only issue. after about a week you will see the smoke if you are getting too much oil...on that T25 it could be less time than that.

if you use a -3an oil line it will reduce the oil pressure enough to where it won't blow your seals in the turbo. i'm using a -4an line and no problems even with a 87'300z turbo.

As far as adding more oil to the system, I've always just added about an extra 1/4 of a quart to all my turbo setups.
