Just imagine an engine faster than the Novamax P5 or the NSR 5 port!! 
I don't think the NSR version of the Novamax (called S5) would be faster than the P5 Novamax. The piston does not make the engine faster.

Quick question though, is P/S set available for NovaMax?
Not too sure. But I think it's the same as the ordinary Novarossi S5 / NS12 piston sleeve set except for a very slight mod on the transfer port. That's about it.
