My white S2 1.7 had a 1.5 gearbox and did 3500 revs at 60 mph in 5th gear which fits in with the 1.5's top speed. My girlfriend's S2 1.7 has a standard gearbox and does 3000 revs at 60 mph for a top speed just under 120 mph.
Okay so I've now fitted a standard 1.7's gearbox to my 1.7 as second gear went on the last gearbox. I can feel that the gears are longer, but strangely at 60 mph the rev counter still shows 3500 revs!
I used the speed sensor from the 1.5 gearbox in the 1.7 gearbox. Are they different? Am I really speeding and doing 70 not 60 at 3500 revs? I don't want to find out with a flash in my rear view mirror.

Speed sensor doesn't do anything but read pulses from toothed gear inside gearbox/diferential axle.
So question is how many tooths has 1.5 and how many 1.7 gear in dif?
I don't know answer to that, but you should be able to read number of impulses for 1km or mile on sticker on speedo white casing if it differs swap speedos.
Cheers
