I have 1994 E36 320i M50B20 automatic, vanos non EWS and siemens ecu
I have full donor car 1997 E36 323i M52B25 Manual transmission with EWS
I also have crank, conrods and pistons from E39 M54B30 and M54B28
My plan is to upgrade M50B20 engine but keep it with auto transmission.
reading over the internet, my options are:
1. Swap M50 to M52B25 and use M54B30 crank and conrod
I need also to swap ecu, ECU wiring, EWS, key
2. Keep M50 engine and use M54B30/B28 crank and conrod without bore up and keep 80mm pistons
1. For option 1 & 2, is there anything else that I need to swap? fuel injector? another wiring? What about my automatic transmission, would it be sufficient to handle 2.5L, 2,7L or 2,9L engine ?
2. What is the most recommended upgrade should I take, option 1 or 2 or else?
Thanks in advance...
ps: sorry for my poor english
