If we're talking dry shot, then no, I'm surprised you didn't melt a piston with the 100 shot. The teeny tiny 260cc injectors are your main limiting factor.
It is generally said around the z31 community that 10-12psi is fine with minor mods (exhaust, cone filter mainly, and some form of pressure relief valve, not the stock POV). The VG is pretty stout, but it is limited by the pea shooter injectors Nissan decided to toss in there.
