DO ANY ONE KNOW'S IF A FULVIA COUPE 1.3S OR JUST 1.3 FROM 1967 TO 1969
WILL FIT A 1969 FULVIA BERLINA GTE 1.3 S1, THE REASON IS THAT THIS TRANSMISSIONS FROM THE COUPES ARE LONGER GEAR RATIOS, WHICH I NEED BAD FOR MY GTE. ANY CLUES. ADAN

Re: LANCIA FULVIA GTE 1969
Dear Adan,
It is just the end ratio that changes. I drive a GTE with a 1.3S engine and gearbox. It works fine and saves you 400 rpm at 120 kph. A 1.3 engine will fit as well and will be more suitable for a GTE since it has more torque below 4500 rpm. With a GTE you will hardly do more.
The top speed will not change.
Your speedometer will have a slightly different reading because of the bigger tyres. With mine that means that it reads exactly the right figure now, since it was too optimistic before.
I think the gearbox change lever has a different angle of the coupe. I do not remember how it was before, but it gives no problems with the seats for gear 2, 4 and R.
The rest is the same.

You have to swap the input shaft as well or use the clutch disc from a coupe. The hole in the center is larger for the coupe.
Theoretically you should also swap the cog wheels for the sender for the speedo as these depend on the tire size. As Walter says, having the coupe sender may just compensate for any optimism in the speedo itself. Remember however that the speedometer and odometer are two different things which happen to be in the same instrument. If you keep the coupe sender, your speed may be correct but the mileage may be low.

Re: LANCIA FULVIA GTE 1969
Fortunately, it turns out to be even simpler than all that--just swap the tires. After speaking with Adan about this at some length, it turns out that the car is running tires that are smaller diameter than standard--they're lowering the effective gearing. Changing back to the correct size should resolve the problem.
