ok this is kind of a dumb question i know but what size is the bolt on the cold side to clock the turbo. i know the hot side is a 10 but i cant figure this out and i feel really stupid.

Its a t3/t04e 60trim by garrett

thnx in advance

 

take a set of wrenches and try them all? 12mm? 13mm? The bolt wont magically melt or something if you try the wrong wrench....

 

Probably 1/2" hex head.

 

both are a 13mm Hex.
