I am running a 1999 KIA Sportage motor in my truck now.
Some slight corrections:
KIA bought the tooling rights for this motor (often called the FE3) and started using it in the Sportage. They modified it for the '99 and up versions, correcting some block web reenforcement issues. The motor was BASED on the older FE block but not the same block exactly. The Mazda F2 motors are similiar but not the same (they are 2.2 vs 2.0 and I believe that extra displacement is in a taller block). The F2 motors are the turbo charged ones. The F2 and the FE motors are 8 and 12 valve motors respectivly. Mazda made this motor a 16 valve head DOHC motor but A) only for right-hand-drive markets and B) only in FWD applications. A "j-spec" FE3 will have a distributer, intake manifold, and thermostat housing on the "back" of the motor and will bang up your firewall if you try to put it in a truck.
Thats why I went with the KIA motor. After alot of debate, the KIA and the Mazda versions of the FE3 are pratically the same; same valves, same cams, etc. KIA detunes the motor via the fuel map and tiny fuel injectors.
Motor swaps can be simplified by using the donor wiring harness nad ECU but I've yet to see anyone ever get their hands on a j-spec FE3 ECU so aftermarket engine management is the only solution.
There is LOTS of support for the SDS system running turbo and NA FE3's on .
It boils down to time/money/desire to be unique.
Speed costs money, how fast do you want to go? lol
Enjoy!
