I have a 328i touring and i am thinking in re bore the engine and go was big has the engine can go. I only need a word from people with more experience than me. Im thinking in s54 internal and had all the head builted. I just want more opinions on this crazy built. No swaps just m52 built engine. In mu country swaps is like killing people you can get jail for them...
