I wouldn't turbo the 2.4 under any conditions. It's a bored out 2.0, and that means less thickness between cylinders, which is not desireable for turbo setup.
Example: Audi A4 used a 3.0 v6, but the S4 turbo was a 2.7. Same engine, Audi just reduced the cylinder size by adding strength between cylinders. They then did the same thing with the newer v6 3.2, reducung it to a 3.0 for the turbo app.
Besides, a lot more goes into making an engine turbo worthy than just forged rods. There are heat dissipation concerns, excess pressure issues, and increased oil flow design and cooling. Not to mention vastly differing compression ratios, intercooler, and an ECM capable of actuating and monitoring a turbo. Then you also have the adddtl stress on the drivetrain, transaxle, and front suspension(significantly more weight).
I would wait until Kia puts a turbo in the koup(it's gonna happen) and then just trade up...save yourself a lot of headache and a ruined car.
