Hello I am a new user here, and I have a Fiat x1\9 1978.
I want to replace a gearbox from 4 to 5 speeds.
Which gearbox will fit me ?? Is Tampere? Or Ono ??

Hi you can built a gearbox off an Fiat Ritmo 65
you must juse your house off de gearchanger clutch
everthing fits but look out for the right type off tripode

...if your four speed is in good condition I'd have a haggle.

i can get a tempra 1.6 with the gear , can i take the inside tempra gear and
put it in my 4 speed gear make it five speed gear?

I would guess there wouldn't be space for the 5th gear in the 4 speed housing? but I'm not sure.

The other option is to convert to cable operated gear change but this is also a lot of work.

Best find a second hand 5 speed box. Although with values of 1300 cars increasing, would you be better off living with 4 speeds to keep it original?

I have just fitted a Tempra 1.6 to my 85 X1/9 but kept the original X1/9 5 speed box.
