Converting From Sleave To Ball Bearing Turbo

[Sarumatix]

Not a skyline but a silvia this time , i'm changing the T25 over to a Jap spec S15 T28 which is BB. I heard from a mate that it is not a good idea to just connect the lines up and drive away, you should regulate the oil pressure down. This is because BB require a fair bit less oil than sleave bearing turbos and that excess oil pressure will kill the bearing relatively quickly. I vaguely remember seeing a device for a such a conversion on something like nengun but I can't find anything now. Anyone know a place I might find such a thing?

its not the oil pressure, but the oil feed thats the problem. get a line made up from pirtek or some other braided line manufacturer with a 1-1.5mm restriction in the banjo fitting. it should cost around $80-$100 to get made. just give them your old oil feed line + banjo bolts and they'll get the new line to match.
