It is my understanding that it is a Garret TB 2568 that was used in an Isuzu truck. Not very common. It is modified by Sonex to get rid of the divider between the exhaust and wastegate on the exhaust side of the turbo. Good luck finding a gasket for that side other than from Sonex. I've been using permatex exhaust gasket maker but can't attest to how well it holds up over time. My Turbo won't spool up if it sits for more than a few days without flying so as a consequence I've had my exhaust on and off several times. Hopefully the Turbo will "break in" next spring when my flying season starts again.
