bolt pattern?
 

Is the 88 rx7 bolt pattern and size etc, the same as the new rx8's ?

Assuming, from your lack of information, that you are talking about the rims I can tell you this. The RX8 rims are not the same width or backspacing as an FC. The lug pattern I am not sure about.

so what you're saying is that the rx8 RIMS will not fit on my rx7??

I searched for "rx8 wheels" and came up with this in about 10 seconds:
