QG16DE may not even be available.....!!! It will be a rare find.
QG15DE swap cost should be around 45~50K after adjusting the old engine (All inclusive: engine, installation, wiring, fuel pump - they will handover the vehicle in running condition to you; wiring issues, AC etc. you should manage yourself later)
If you want N-CVT, go for QG18DE (The engine will cost the same, but you will need to make some other changes to transmission and suspension to withstand the high torque!!!)
