What cars had these? Trucks? Any performance potential at all or just a econo-lump?
-thanks
The FS is from the 2nd generation Probe/MX6/626 and the 9th generation Protege. They're pretty much an econo-lump.
In reply to alfadriver :
The FS predates the MZR, it was used in the Protege and 626 in the late 90's and early 00's.
It is a decent little engine but they didn't have a great aftermarket when they were new and common, I doubt there is much out there now.
The Mazdaspeed Protege has a turbocharged FS-DE that had...problems. In Japan they got the FS-ZE which was a zingy 170HP naturally aspirated version.
