Youre helps much appreciated mate! Thanks! 
You racing ovals?? for 1/4 mile oval in rosegreen here in ireland i use the boxy k10 4 speed gearbox on the cg10, works perfectly....i just get valve bounce at the very last moment before its time to back off for the turn, according to rev counter thats 7900rpm (but probably closer to 7500). You need the the k10 4 speed clutch plate but need the early cg10 flywheel.
Only problem is that the gap between 1st and 2nd is quite big, i find i have to slip the clutch to keep the revs up when going from 1st to 2nd off the startline. Tough little gearbox too, have not broke one yet (although the cg13 with 12:1 cr and bike carbs with 270 cams and custom exhaust manifold that will be done soon might change that...lol )

Can you post up the ratio's for 1275 too please.

2nd in 1275 is 1.955. 2nd from the 1348 is what you want at 1.782. although I see the 1348 has the same ratios as the from 2000 on 1.0L apart from having a 3,895 final drive.
Thanks much obliged.
Yes lord lucan! Thanks for that mate will be fitting that shortly thanks everyone.
will be fitting that shortly thanks everyone.

to turbo or new lump :/ hmmm
does this mean me bolting a cga3 to my coilpack 1.0l box has no difference but 5th gear?

no, it means you have the same clusters, but a lower ratio diff
Belly93
to turbo or new lump :/ hmmm
whaty does this mean in terms of acceleration, top end speed and what not lolno, it means you have the same clusters, but a lower ratio diff

your 1.0 box is like fitting small wheels to a 1.4 k11
Belly93
to turbo or new lump :/ hmmm
i mean like acceleration or not as quick top end speed, i didnt word that very well sorry :/ lol i aint that stupid well i hope not seeing as im a mechanic lolNo it means instead of having a 998cc engine you now have a 1348cc engine
Belly93
to turbo or new lump :/ hmmm
which in turn does what is what im asking frank? is it worth getting a 1.4 box?
frank
Club Member
well if you fit smaller wheels the rpm is higher eh, so a 1.4 box would drop your revs
A taller diff has to be preferable on a road car. only you can answer that question really, if you want a bit of economy and a more relaxed motorway cruise then yes, if you want to tear about flat out using full revs then perhaps no.
It won't help. My 1275 does between 45 and 50 mpg, I get 50 mpg+ on long runs at 70+ without trouble.
Belly93
to turbo or new lump :/ hmmm
so for better economy id be better off with the 1.4 box?
Yes, without a doubt.

nice thanks for the help
possibly be done when funds allowThose ratios posted above, I assume the diff ratios are different in each gearbox, be interesting to know " whats what ".Also are differentials swapable between k10 and newer Bubble micra s. even knowing whats the lowest diff . that will fit into a K10 WOULD HELP .4.05;1 seems to be the lowest I can find .
whats the gear ratios for the 4 speed k10 gearbox lads?
so the 2nd gear in the k10 gearbox is longer than the k11 2nd gear?
frank
Club Member
same as the 5 speed according to haynes nate
Yes mate but we have a 1998 hotrod car and we need a longer second gear so if i fitted a k10 gearbox would i have a longer second gear?
frank
Club Member
no, but 3rd 4th and 5th gears are taller

there,s another thread running here nate http://micra.com.au/community/message.php?messageid=80024
in a 4 speed k10 gearbox frank?
i just really need to know whats the longest second gear to fit to a 1998 k11 1.0

the k10 type 41 is
3.412
1.958
1.258
.921
.721 (5th, if fitted)
k11 type 41 is
3.412
1.958
1.323
1.028
.850
so the k10 has a taller 3rd 4th and 5th nate
hmmm no difference in the second gear so mate! thanks for youre time , one last qs , do you know the longest second gear that will actually fit in a 1998 model 1.0 , and ratios too mate? Thanks very much mate im badly stuck

Thanks very much mate im badly stucki dont get where your going with this, what size of an oval are you racing? how long are the straights and what revs are you currently pulling at the end of the straight?? The k10 box with 3.8 final drive is ideal for a big oval like tipperary, i dont know of any tracks with longer straight where a longer 2nd/final drive would be needed. more info on the track you are racing is needed.
What problems are you encountering?? and what work is done to your car

Ah, so now i see the difference between type 41 and type 30 ratios, and the type 30 has a 4.65 final drive. What is the final drive in the type 41 then?

As Frank says, his mistake, lost in the mists of the mind
Hi all. I am new to the Micra Scene and I write from Italy. I recently got hold of a 1994 1.3 Super S and was wondering if somebody put a different gearbox to shorten the gears and improve acceleration, since basically top speed isn't really a key feature. Would the gearbox of a 1.0 fit p&p and make a noticeable difference? What year/model would be recommended in case to proceed with the swap? Thanks!
Thanks mate!
