dangerous brain Posted August 16, 2007 Share Posted August 16, 2007 Is it normal for a dbb turbo to have a restrictor fitted in the oil inlet housing? I ask as my journal bearing turbo has nothing in this fitting and the new one has a restrictor of some sort. Almost like a thread filter. How much shaft movement do you get from a dbb turbo? Seems to be more axial movement on this new dbb than the old journal one I am removing for worn bearings? Also do turbo's require a bed in time and if so how long?

TrickTT Posted August 16, 2007 Share Posted August 16, 2007 Dbb turbos only require an oil mist on the bearing, so yes, they should have a small oil supply hole. Cant help on your other Q's cos i've never played with one:) Link to comment Share on other sites More sharing options...

dangerous brain Posted August 19, 2007 Author Share Posted August 19, 2007 Hmm I am kind of a bit worried about this now. The turbo unit vibrates quite badly when cold. I'm wondering if its taken a knock in transit. I'm sure its not meant to have all the play in the shaft that it has. Still it pulls alot harder than it used to.
