Ah ok, now I know wat you are on about.
There is such a car but it is called the R32 GTS-4.
It has the GTR AWD system with an rb20det. But it is not reffered to as a GTR although some loosers call it a baby GTR. In actual fact the car is pretty underpowered to make good use of the AWD system. With quite a few mods it might be a decent car, but otherwise I would not think so cause it has the power of a gts-t but is heavier due to the AWD and therefore slower. Unless its pouring rain, lol.
