For the record, the engine code for the GT which has a stock power output of 127hp, is the BP05. Definitely a worthwhile swap if you can't source a zetec, and they handle boost extremely well up to 14-16psi, then you need to lower the compression, and put forged internals. Peppy little engines for a FWD.
My GT, with the cams, intake mods, and flash was putting down 159.3hp/133.1lbs foot. I have the dyno sheet but its on my old computer that my bitch ex wife got in the divorce... it was pretty quick for an escort lol.
