Yes you would have to change axles, engine mounts, PCM (computer) and much much more. You would be better off selling your car and buying an LS. Trust me the time and money spent would not be worth it. If you want a zzp engine and trans (my dream also), I would look for an LS impala with a junk engine which most of the time is just a LIM (Lower intake manifold), UIM, or Head Gaskets. Then, I would rebuild or fix the junk engine and sell it. Then, use that money to buy your ZZP stuff of your dreams.

maybe someone smart will see this , I too have a 2 002 pos impala 3.4 ,,, the bcm won't tell the pcm to run it bc of passkey. I'll drop it in the pond before I give gm another dollar. But before that ultimate day ....is there a pcm that will run it that is easy to bypass the security .... Like with vats.? Could an older or newer pcm programmed to an older or newer model still RUN the 3.4 engine etc yet be tricked out of looking for the bcm's passlock blessing. That is , everyhing would be the same except the pcm still driving a 3.4 but maybe thinking it's an ilumina or something else?
