As far as I know that turbo never came on an EJ20T in North America. Look for a 91-94 Legacy Sport Sedan with automatic transmission and EJ22T engine. They had the VF10. The sticks had the VF11. I have some VF11’s at my shop but they could all use a rebuild.
The European, Aussie, NZ, Japanese etc. version of this car, the Liberty turbo, was an EJ20T and the auto tranny models had a VF10, but I doubt you’ll find one of those around here.
