Nope.
You're talking about putting a Hyundai engine where a Mitsubishi engine originally sat. If you look at the two engines side by side, the first thing you'll notice is they sit on opposite sides of the car.
They are actually two COMPLETLY different engines. The non-turbo S-Coupe motor being like the 1.5L Mitsubishi engine in the 90-94 Excel, while the Turbo S-Coupe motor (G4EKT) is in the same family as the 1.5L SOHC in the 95+ Accents.
You'd be best off trying to find a Mitsubishi motor (or Turbo Dodge Colt) and swapping that in.
