I'm thinking about purchasing an 06 k20z1 from a 2006 acura rsx complete with tranny, axels, ecu and wiring harness. I'm curious first of all if it would work and what I would all need for it to work. And will it be generally plug and play?

Still more you need. It's not going to be plug and play, it's a different family of engine than stock. I'm not familiar with the 6th gens much but you would still need swap mounts, swap axles unless stock RSX fit, figure out power steering, figure out A/C (if keeping), some sort of harness adapter for the RSX engine harness to Civic, radiator and cooling hoses, fuel/vacuum lines, air intake, exhaust, etc.

I have no doubt that engine and trans combination has been put in a 6th gen, but it's not as easy as a B swap would be.
