I have a 1994 CG10DE K11, originally sold new in Japan.
It has the RS5F41A box & puny CV's / shafts.
They're probably rare in Japan because they've all been sent to NZ, ha ha. The K11 was never sold new in NZ. About 95% of K11's here are CG10DE, maybe 10% are 5spd. I've only seen a handful of CG13DE 5spd advertised.
Converting a CG13DE powered K11 with N-CVT to RS5F30A is a really good option knowing there won't be the expense of making up half shafts. The gearboxes are plentiful & cheap from N14 / N14 pulsars with GA15 engines.
