im in a situation where i need to either fix one of my turbos or replace with a second hand unit or brand new one


my original t25 has been modified for my setup, ie flange welded to compreffor housing and i think a carbon seal. i had replaced the viton seal once when it got crushed and lead heaps of oil when runnin but after that another time i think the bearings ran dry and blew somoke again so i replaced it with a second hand t28 which also #### itself bearing are stuffed in that to as it has heaps or radial movent.

not to sure what to do rebuild one of the cores and get it ballanced or get new turbo??????
