RS5F31A gearbox into K11

looks like it can be done after all, forget the custum driveshafts, looks like everyone has been barking up the wrong tree

all you need is the diff out of your old rs5f30a micra box, if using the old bearings you also need the diff bearing races out of the casings and press them into the 31a casings, swap the 31a ringgear onto the 30a and then reassemble.

You now have a 31a with smaller splines to match k11 driveshaft like the exa 31a box, which I'm guessing just needs the pulsar casing and would be a straight bolt up.

I will confirm this info later when I get up later today and finish it, its 4am and I'm rooted, nite all

if any one has some old cvt auto driveshafts let me know, I want to check one out

nice one rudy :) what will be the gains ?
and i checked some CVT shafts and diff a while back, they were just normal splines

fuck it, ringgear bottoms out on casing. back to the drawing board

look like the 30a and the 31a only share the engine side half casing, this incorporates the bellhousing and diff casing and I cant see why you couldn't interchange them. the bigger(wider) diff holds the bigger ring gear higher and the corresponding gear on the gearset is higher which is why you cant hybridise them.

Am I finished, no way, 31a's came on n13's as well and had the smaller splines to match micra, it may have the same diff as k11 but with the bigger gears, it also came with 31v, don't know if its true yet but apparently the GM motors fitted to aussie n13 Pulsar had bellhousing pattern changed to fit Nissan boxes

so far this is the list of motors that use the same bellhousing in Aus

CG13..., GA16...., CA18(exa)....,GM 1.6-1.8(n13)????

any protons in aus rudy ? http://www.micra.com.au/community/message.php?messageid=80024

not many, notice how the n13's are left out
