Not really. The timing would be retarted slightly...and you wouldn't feel the decrease in power. There would be no long term disadvantages to using <91 octane in the GS-R. The higher octane rating is only required since the C1 has a relatively high compression ratio.
That said, I always use 94 octane in mine
