They will work fine, I do believe you need the A3's knock sensor as well, seeing you will be also reusing the A3's charge harness.

Acura carries the A2's starter as a reman now, alot cheaper!

Supposedly there is a conflict in the connector/knock sensor keying between the different engines. I used/use all A2 components.

so using the A2 harness with the swap i should be fine? But using the k20A3 Alt. & starter on the A2 should be good to go to.

Yes using the A2 harness will be fine, the plug on the knock sensor for the A3 is different then teh A2
