iim not sure but , you will also need the ecu for the 4g63 , the mounts might be different because the tranny is on driveer side for the 1.8 and passenger side for 4g63 , plus the front axles. besides that you just need to see where the mounts are , and if the mounts are layed out different , just get a cross member from a junked 4g63 1st gen and swap that also , what you looking for turboed 4g63 or non turbo which the non turbo galant has?
