  • FSDE Head questions

    Hello all,
    I have had this itch with this engine that I cannot seem to scratch. I want to "build" one of these FSDE motors (no need to get off topic I know this engine isn't a power house), but have a few questions regarding the head.
    1.)what is the head combustion cc of the head?
    2.)flow rating of head (stock ports)
    3.)what numbers have been yielded out of ported?
    4.)max power made on ALL STOCK BOTTOM END? (boosted)
    Thanks in advance.
    so many possibilities...

    I doubt you find much info on the FS-DE here. Scan the Protege forums (MazdaSpeed and Protege5) on for some info.

    I've tried several normally aspirated combos of cams, heads, mild porting, and ECU tuning on my endurance race car. It's not gonna make a lot of power without boost though.
