It will bolt straight on ,but the v23/24 have different flow characteristics,and for that reason unless you are thinking of having the car remapped it is best to put on a vf23 as a direct replacement imho.
Vf 24 has more bottom end grunt and a smaller exhaust housing than the vf23 which means it spools up slightly quicker,but the vf23 has more mid range punch than the 24 .

Your ecu is set up to run boost for a vf23, if you just stick another turbo on and hope for the best what do you think could be the worst case 
. It might run ok for a while but eventually something will let go. Think about it logically if we could all just put a turbo on and forget about it, the likes of jgm, bob Rawle , etc would not be needed
