WET FLOATING BEARING!!, unless this is a BALL RACE turbo they all are, all have two bearing which float the shaft.
Cannot confirm what size is standard for comp and turbine as I don't know for these.
All thye do is use other parts from other turbos to mix and match to your requirements.
Just using a phrase like wet floating bearings would put me of, I would phone around a few people that do a lot of these cars to see which size comp + turbine size would be best.
Just out of interest how much ?
To tell the difference, you first need to know standard size comp and turbine wheel and then look to see what new ones are, then hope it is not shagged, people can be very "loose" with their opinion of whatv is good and bad especially when selling.
