QUOTE said:A user who’s provided legit proof that he has the retail version of Gran Turismo 5 has revealed what the game’s initial install size is.
The initial install size of Gran Turismo 5 on your PS3 HDD is going to be 6.4 GB. He also revealed that it takes about 40 minutes to install.
However, interestingly, he says that the game will continue to install and decompress data throughout the course of your playtime and the actual disk space taken by the game on your PS3 will be a lot more.
