Up for sale is a Mazda Borg/Werner K04 Turbo that came off of a Mazda CX-7, the turbo was replaced under warranty for some oil burning.
I would highly recommend doing a rebuild on it (replace the oil seals) before using it and shaft play is normal for this type of turbo (I've compared it to a brand new out of the box turbo and it is exactly the same)
This turbo will fit any 2.3L Mazda 3,5,6 or cx-7 or if you make your own flange on the header it can fit, and would be good, for any 1.5L to 2.3L engine or you can try to fit it on your bike.
I had originally planned to fit it on my car but I bought a Motorcycle instead so I no longer have the funds for a turbo project.
PM me with offers or questions
thanks for looking
