Only thing I can find on the N1K-2J is that it has a max speed at 369 Mph. It says nothing about which altitude it has this speed, but according to bombjacks link the Spit IX is allready a lot faster than that at 16K with its 383 Mph If we assume that the N1Ks 369Mph is measured at its best alt, then the Spit IX should be a lot faster than N1K in general. The Spit IX reach the max speed of 409 Mph at 28 K.
But what about the Nikki Mitsu? It could be very interesting if you could find some more detailed info on the N1K-2J. Maybe even a performance test by the Japanese authorities like the one of the Spits. Could be very nice if you could find something and post it here.
