gts-t or gts-4?

im trying to decide between the gts-t and gts-4 or even just wait a couple more months and get a gtr ohh yes all of these would be a r32.

i real a lot of stuff so far from what i understand the gts-4 does not have the low end torqe to really take advantage of the awd. other than that thats about all i know. if i got the gts-4 i may do a engine swap in the future to a rb25 or something similar. i was wondering if anyone has any suggestions on what one to get and please if you have never drove one i dont want to hear your 2 cents
