in this case.. i would suggest to sold the car as it is and get the car which can last good 5-6 years
the swap thing works 50/50... the mechanics who swap are not good ....the mismatch of JDM vs PKDM and difference in most of things make car as useless as piece of crap many times.....
the owner later sell it for even less than its actual price with weak or bad engine due to stamped of ENGINE SWAP ha....
Priorities in end.. swap is the quick money for hathora chaap mechanics and less headache...
engine works or not...banda jane ..kabari jane..
