Turbo was bought at ATP, but they could not tell what it is when the buyer emailed them now

Garrett serial11010504) 755246-1

Turbo was actually ordered for a VW G60 Turbo kit, but is now fitted to a 16v. It was ordered in place of the T3 60 to spool faster....

It is also physically quite a bit bigger than the T3 (T34) used by Ford in the Sierra Cosworth

the inlet is roughly 50mm at the turbine, if that helps

Also cast in 0,64 on the housing if that helps

 

most likely you will need to take the housings off and measure the wheels.

 

gt28rs maybe? at least it appears to match one.
