ATPUSA said if i follow his recommendations of using a restrictor it will be covered under warranty as even gt35 they fit the restrict the oil im just goin crazy here cause the last few garrett BBs turbos have died do to a normal fitting as do most fords with the same fitting so im not to sure what to do here its on a rb30det yet to be fitted back into the car so i cant excatly test how much oil pressure it has
this is what they said
Jayson, have a look on the “turbobygarrett.com” web site (select Turbo Tech, then Basic, then Oil and Water Plumbing) it shows the max oil pressure for a Garrett Ball Bearing is 60psi, more than 60 psi may result in oil leak issues
