Here are the ratios as we worked them out, they are not the Nismo middle or ultra close but a mix of the two. They were sourced from a well known New Zealand Nissan race and rally
driver who drove for the factory so they may be a factory "special". 1st 2.544 2nd 1.908 3rd 1.221 and 4th 1.000. It's a good combination without the too tall ultra close 1st gear.

hi stirlingmac ,do you know if it is middle close ratio or the ultra close
ratio gear set.
the gear counts for the middle close are
1st/30t 2nd/25t 3rd/23t and 16t/20t/26t/29t for the cluster gear
the ultra close ratio is 1st/27t 2nd/24t 3rd/21t and 19t/23t/26t/29t for the
cluster gear.
I am interested in them for salom racing.
thanks bob

I dont think its worth it for the 4-speeds. It might be allright for on the track. But even then im sure it would be only used on certain tracks. I think most circut 1200's
would use 5 speeds anyway. Well mine will be anyway. Problem is, there too weak for race preped engines!! Thats why the celica box is a good swap. Good luck to him trying to
sell em.

I've tracked down a complete unused close ratio gear kit for the 1200/120Y 4 speed. It is the later model wide tooth model which was developed for the 120Y. I don't have the exact
ratios in front of me but it has the really tall first gear. It is mint and still wrapped in wax paper. A friend has it and has offered it to me first I can't afford it but some one out
there must want one. He wants around US$500.00 for it. I'm in New Zealand but I could arrange freight anywhere. Any takers?
