Any standard R5K or R6K PGM-II will be fine, and will happily work for motors reaching well into the high 60's... maybe even more, but I've not actually seen an MC18 make more than that yet. Not saying they can't, just saying I've not personally seen it.
Unlike some other marques, (standard) PGM swapping has no effect on the NSR. Any PGM-II will produce exactly the same results on any MC18 Mk2, just as and PGM-III will work exactly the same on any MC21. No need to look for any "special" code on them, or PGM's from SP models... they're all essentially the same.
