So many responses, so little info.
1. Nobody has mentioned that the gearboxes in 4g63 and 4g93Ts are AWD. If you are going to use the gearbox in these conversions you need to lock it to FWD, which will cost you roughly 2k for parts and install fee. With the 4g93T swap you can use the standard SOHC 4g93 gearbox, but it is not a direct bolt on. You need to modify the clutch slave cylinder to clear the turbo's wastegate. Josh bought his already modified which meant he didn't have to do this.
2. Halfcuts are the best way to go as you get all the parts you need for a swap. The swap is not as simple as unbolting the engine and putting the new one in. You need all the extra bits like intercooler and piping, airbox and piping, manifolds, bigger brakes and 5 stud hubs setup, wiring, ECU, etc. By getting a halfcut, you get all the bits you need and is the most cost effective way. Trying to source all the little bits on top of an engine can be difficult especially with imports and the costs add up quickly.
3. What skills, tools, knowledge does the OP have? No matter what you read on the net, swaps are not easy if you don't know what you're doing. There's really only one way to learn and that's actually doing it, but if you haven't got some basic mechanical knowledge or somebody helping you that does, then either of these swaps are probably going to be a bit hard to handle.
4. 4g63s and 4g93Ts come in both CC and CE orientation. If you are going to buy one, you have to make sure you get the right series as your gearbox, timing belt, intakes, etc are all reversed between the series. If you are buying a 4g63 setup you need one from an evo 4-6. If you are buying a 4g93T you need one from a CM5A model. CM5As are a great option, but are rare as hell in aus because the car was never delivered in Australia, and most importers don't bother with them and go straight to the evo engine.
Hope this helps
