are you wanting is to keep the 8v head with the b22k bottom end?....it has been done, and there are a few threads on here...mazda had a magnum motor (8v b2000 engine) that they sold over seas for a few years, it was supposedly a turbo variant, but no proof of the turbo, just the engine, and nothing about parts (intake & exhaust mani's) and had @ 120 hp ish.....next option is an aussie 12v head from a bongo engine, same as the probe gt and 626 gt (f2t motor), just the dizzy is on the front of the motor, not the back causing clearance issues with the fire wall.....the intake and exhaust mani will work, but the intake will need to be flipped and what not, so it isn't just a "plug & play" swap, but can be done pretty easily with all the right parts and should come in @ 140 hp or so that was what the p-gt & 626 gt were rated at...now the best bang for the buck is to get a kia sportage 16v (basically an fe3t) with a nice turbo setup, and a stand alone ecu, and you can get close to 200 hp or more with this setup, which is the stuff in the links provided earlier in the thread...
there are several threads in the engine section that have a lot of info on it, and you may be able to find some more info on mazdatruckin.com aswell...good luck!
