All the new Garrett GT series are BB hence making the 2835 ball bearing.

[giz01]

core section of the BB's are bigger than plain bearing type plus the oil inlet has a oil restrictor in it to stop too much oil entering!

think there is a screw/bolt or something on the core as well for the tension of the bearing ? best to talk to a turbo supplier i guess instead of letting us in the know? tell you what we heave heard?

t04 e is non ballbearing

2835 is

[Joe]

T04e are 2 hard 2 know if its a ball bearing unit or not

only because of the fact that they have been rebuilded like a high school s*art

My T04e is a BUSH type turbo & before i fit it on i will rebuild it, $400 from GCG if theres no problems with the turbo + another $300 if i want the unit to become ball bearing.

when you go to buy a turbo from gcg for example they will ask you for a specification of how you want the turbo & build from there

Housings is depending on budget

t04 t04e ihi etc etc!

i do not work for gcg

Sorry, a bit OT but I have a question in regards to turbos too:

How can you tell if the turbo has 270 degree thrust or 360?

Thanks.
