R34 Non Turbo Diff Change

[r34_25GT]

As most of you know, the 25GT's unfortunately come as single leggers =(

i posted a similar thread in the NA section of this forum, but havnt quite recieved the information i was looking for. Doing some research i found that the manual non turbo 34's came with a 4.363 diff ratio. My initial plan was to just directly swap my current diff with a r34 lsd turbo diff, however ive been told that they dont mate up and i need to look for a r33 gts-t diff.. the diff ratio of a 33 gts-t is 4.111 and im not sure in what way my car is going to react to this??

just wondering if anyone has had experience in putting a standard lsd turbo variation diff onto their NA skylines..im not really mechanically minded though i do know the basics, if some one can please clear this up for me it would be great
