How hard would it be to switch from my 00 d16y5 to a d16z6? I know that I would need a new ecu, the p28. But other than that, what would I need? Would I need new motor mounts? Would the d16z6 harness just plug right into my firewall plug? Help me out, I found a good deal on a d16z6, ohh I also have apexi turbo kit to throw on. Let me know.
