The 3-cyl will bolt up to the transaxle, but there are other changes required to do the swap. You'll need the 3-cyl axles, ECU and maybe wiring harness. I'm not sure about the newer cars, but on the '89-'94 Metro/Swift, the engine mounts on the body are different too. So not a simple fix.

The 8-valve would be almost as much work. It has TBI and will require the correct wiring harness and ECU. Also the valves might not get along with the 16V pistons.
