Re: More Ebay turbos.... Borg Warner this time....
 

Depending on the application, you could use them as compound. You just need to be aware of how they work. IF your engine is about correct, they should boost nicely. more or less progressively gaining boost with speed. They are matched to eachother, but you need to know if there was an intercooler between stages and how big it was. All makes a difference.
