you can swap the swift motor pretty easily as long as you get the entire wire harness, ecu, gauge cluster. the blocks are the same 1.3l, so no custom motor mounts. the swift has the twincam head. your looking at 30 more hp between the two motors. plus theres a ton of aftermarket support for the G13B. also the internals in the G13B are forged, unlike the sami 1.3l or the tracker 1.6l which are cast.
