it will need an intercooler, tranny, transfer case, transaxles and ecu.
I have a intercooler for sale also.
the car had a 90 t-case and 90 trans (i think the trans is bad, but the clutch is fucked in the car so the trans might be alright) those can go with the car for 100.
basically the car will need 500-800 to actually run and drive. Most galant's that are together bring a minimum of 2500 running.
