The pump is the same but reservior can is different. Celsior has intergrated reservior can and Soarer has remote can. Depending on your application, but Celsior would work the best. If you are interested, I have a brand new Celsior PS pump with intergrated reservior tank and I can throw in a used but good remote oil reservor can too. PM me if you are interested. I purchased last week thinking about using it in my SC470TT but doesnt work on VVTi style engine. I think all VVTi PS reservior cans are remote mount.
