I just found a turbo and i'm not real sure about spec's on it the id plate can't be read. i have some pic's . comp housing has airesearch to4 on it and .60 inside comp neck. the turbine housing is kinda big but has no numbers or trim size on it.

 

Ok i have cleaned up the turbo and removed the paint and id plate on under side of comp housing below are the numbers i got from it..

Top line (735030091)
Bottom line (620927-146)

Also found the letter and number M10 on neck of compressor. And numbers on turbine housing also A/R 1.32

I hope I'm not wasting my time fooling with this turbo if it can't be used..

 

what motor?

 

It's a 302 in a 1989 mustang.
