My father's friend imports JDM Cars into the US and sells em off pretty cheap, so i was thinking of getting an LS and turbocharging it, then somewhere down the road in know the engine will die sooner or later so i was wondering about putting a USDM engine in it when the time comes. I'm pretty sure since you can drom a JDM in a USDM that you can do it vice-versa, my question is what will i need to do to get it working? ECU? Re-work piping/wires/hoses since it's a RHD? Any thoughts or answers?
