well it doesnt neccessarly need to be a bigger engine. i could go with a B series 1.6 or 1.8, but only if i can get the money to do such a swap. finding an engine an fabbing up mounts isnt too hard. but having axles sized to fit, redoing the car's wiring, and setting up a new fuel system is my main concern. that which all of costs a pretty penny compared to throwing another A20 block in using the head i already have.
