S13 71C vs S14 71C - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I read some where that the S14 71C transmission is internally stronger then the S13 71C? (the transmissions guys everyone knows engine codes but you can't figure out transmission codes or diff codes get with the program.)

Can anyone confirm this?

Same transmission, minus maybe a double cone synchro vs a single cone. S14 SR transmissions have a different 5th gear ratio as well.

SR/KA/CA are all the same 71C transmission correct? besides bell housings.

Not sure about CA transmissions, but generally speaking, yes the KA/SR is the same transmission with minimal changes through the years. KA/SR is a bellhousing swap away from working.

Not to be a dick, but next time do some research. This was covered maybe two weeks ago...
