Mazda G5M is the old 5-speed MTX used in the Protege, 323, EGT and the ZX2. Some of the ZX2ers, especially, those with the S/R model report problems with the G5M.
I have a ZX2 S/R with ~129-131 HP at the front wheels and aiming for 145+ HP. I have been very careful so far not to hurt the tranny.
I hope the duratec HE 2.3 is available to bolt up to the MT75 or better the Getrag 6-speed in the SVT Focus.
