Hey everyone, im new here. I have a 2009 hyundai accent, and the kms are getting up there. Its the 1.6l gs hatchback. Was wondering if anyone knows if theres any motors that swap "easy and quick" preferably bigger then the stock motor

 

The days of yanking out an old motor and dropping in another of a different size etc., are long gone !
Many modules today are considered a type of computer and going back before somewhere around the early 2000's the late model vehicles are loaded with them.
Because everything seems to work OK, leads us to think "There's nothing to it". The more knowledge you acquire about how modern vehicles are controlled and work the less likely you might be inclined to ,"Give it a shot". Opening a can of worms is putting it mildly.
There are many inputs that go into a Powertrain computer , Transmission control Module, HVAC module and many more. What makes it better/worse there are networks that are part of a system that if one of the modules malfunctions or it's info is incorrect ,problems are now present. from no starts, poor performance, warning lights , including "Limp mode" where the vehicle will not go over 15 MPH. So ,,,,,,,,,,if you can, learn as much as you can, so you have some idea what you are dealing with..
It may not be exactly what you want, but one of the better things to consider might be to replace the engine with the same specs as the original "As Built".
It never hurts to get several opinions from folks currently trained in the repair field..
