Can anyone confirm wether a 25DET box will fit into a R33 GTS? And if not, what sorta work am I looking at doing? If it fits easily, then I'll def. go with a S2 25DET box.

Hey there guys I'm not sure if this has been asked, and if so can you lead me in the direction.. It's finally come time for me to swap out my beloved and molested RB20E and put in a RB25DET. So (assuming that the RB20E box (FS5W71C) isn't rated for the power output of a RB25DET) I'm kinda stuck at a predicament. From my knowledge, the RB25DET gearbox doesn't fit into a R33 GTS housing, so what gearbox? Does a RB30 box bolt in at all, or a RB20/RB25DE? Cheers for any help
