You'll need to upgrade quite a bit of stuff, there is no turbo provisions in the standard petrol FD ECU so its likely an aftermarket ECU will be required plus cam and exhaust changes, maybe pistons to alter compression.
Drive axels and gearbox will need beefing up also.
Yeah it's quickly going to reach a point where it's not economically feasible...
It's likely to require the whole N loom and most of the stuff hanging off it as the normal i30 loom would be missing a whole shipload of sensors and the N ECU.
...of course given the base car is 2011 spec then the N ECU is likely going to think 'hey what the hell is this gearbox/O
2 sensor combination???'.
If the pockets are deep then you'll need to speak to someone like Haltech...but if the pockets were deep you'd just buy an N
I can think of 'worthier' projects (but what would I know, I own a 21yo V8 XR8 Falcon
