The 25t RS FOUR S has:
17" rims with 215/50 rubber standard, the NEO Straight 6 engine, optional twin sunroofs, rear foglamps, and comes in Red, Dark blue, Yellow, Black, Green Pearl, and Silver. Went new for 3,260,000 yen.
The Type-B has:
None of the above, except it has 16" rims with 205/55 rubber and a non-NEO 6 RB25DET (same power as the NEO though... strangely quoted as 280ps). It's also strange to point out that the Type B doesn't seem to have a sound system available for it, not even a radio. At first I thought it might be like an "N1" version, but I think this might be a mistake. It's strange because all this info is taken direct from Nissan Color catalogues. Went new for 3,040,000 yen.
This fully optioned one...
...is going for 1,880,000 yen from a dealer. It's aaaaaall good.
