Sorry to crash your party but I'd be interested to know the ratios for the 306s-

 

1.8 16v xs

 

2.0 8v xsi

the 1.8 8v is showing 4 boxes on service box, but not sure if they would have all been used, as there seems to be only 2 cw&p's available. I am sure Meirion will be along shortly to clear that up!

 

But I was under the impression that all 5 speed 16v gearboxes in the 306 were 4.42 final drives

Shhh the cwp is top secret

 

Cheers Dan!

ha, with that you should be able to find the ratios easy enough on service box

I know from past experience the 2.0 XSI 8v has quite a short box. Makes for a low top speed as the gutless engine only revs to about 6000rpm!

So would be ok in a gti6 205?

 

I've got a really clean really low miles one

find the code off the box and you'll be sble to narrow it down a bit

[DamirGTI 327]

1.8 8v box is :

 

1- 3.45

2- 1.85

3- 1.28

4- 0.97

5- 0.76

FD- 3.94

what code on the box for that? as there are 4...

[DamirGTI 327]

No idea Dan .. it's just something i got from forum member via pm :

 

 

How come theres 4 different ratios for 1.8 8v box ?! .. seems to me a bit unusual , why would they make 4 different ones for the same car with said engine type ? (certainly doesn't sound cheap solution manufacturing wise ..)

Are you sure about that? The 'box off a 306 1.8 16v I had was a 3.94 FD and I've nothing to suggest it wasn't the original gearbox.

Doesn't have to be intended to use 4 flavours. Could be that the ran out of stock of a gear set and took that was in stock... (belt stop -> big $$ loss )

Or that it turned out to be cheaper to use another set.

Sometimes ratios are also related to the fitted tire size / trim / model. (larger rims / break vs hatchback)

A friend of mine has a 306 1.8 16v cabriolet gearbox in his 205 gti6 and that too has a 3.94 final drive.

I feel I might have missed an important segment of info from this, there was a date which they were all 4.42! I'll try and find out as I have it all written down somewhere
