If you already have AWD it is gonna be almost plug and play except for the engine mounts support and cats . Remember in my case the donor car was a q50 AWD and I’ve done all the mods to fit rwd g37.
@@florinel181 so when I was putting the 370z engine into my g37 I noticed I needed different mounts I used my old mounts from the old engine and I bought new down pipes to replace the cats I have those all connected with the new headers
