Hi everyone as the tittle says I got questions about the engine swap
My car is 2006 WRX the engine is destroyed the crank and block is not rebuild able as far as I know.
I do have another engine which I bought years ago but I believe it's ej205
So if I would like to do the swap would I need to change the whole wiring and ecu? As of the WRX came with AVCS but the ej205 isn't .
Or can I just don't plug the AVCS and run it like that.
I do know whatever I did I'll need to get custom tune
Every input will be appreciated
Thank you
