F10 ratios?

[Lewis.]

Does anyone know exactly what final drive ratio I have, and whether it's a close or wide please. reps are awaiting :thumb:

It's an F10 and the code is A025 02 W418

Wide Ratio (the 'W' in the Code)

Final Drive 4.18

This of course assumes that the innards haven't been tinkered with previously.......

[Royston]

Guessing it is an SR box, 5spd wide ratios with a 4.18 final drive

To my knowledge CR F10's were never fitted to Nova's, not sure if they even exist

Only CR box was the F13 fitted to the GTE/GSi

Thanks Colin, I did wonder whether it was something as simple as that.
I don't think it's been apart, as I have a huge folder of history, so I'm fairly certain that it's previous owners wouldn't have been the serious modding sort.

Yeah it's an SR box, cheers, rep has been left also :thumb:

Is 4.18 the lowest final drive for an F10? I seem to be under the impression it is and that they are sought after? or am i imagining that?

[Stuart]

its semi sought after.... not mega money as they are still commonly found. 4.29's and 4.53's are where its at if you can buy for less than £50 thens ell for £100 (much more than that and you might aswell buy a new one lol )

[garyc]

I once picked up a 1.4sr engine and box and it had a cr cluster in, it all looked std too ie never been apart.

I think the 4.29 and 4.53 diffs often go for a lot more than 100 quid, sometimes 250, you can also get them new from vauxhall for abt 300 (well last time I checked)

[Stuart]

iirc new was £250, and fools on ebay pay £300 for them 2nd hand lol

[Lewis.]

cool, cheers guys :)

That's what I'm hoping, I have a 4.5 here in a Corsa road rally car.......

[pottersrebel]

the 4.3 and 4.5 are perfect diffs for oval racing and with a chance of winning prize money equating to about £100 a meeting that £300 can be a wise investment especially when there`s over 30 meetings in a season. there hard to find now same goes for the cr 2.21 second gear they can sell for 300+

Brief hijack here, but isn't the 4 speed box (usually found on things like a merit) a CR box? I know the ratios are different to that of a 5 speed box....

[shed-on-wheels]

f10 were 4 speed nd 5speed bud the f10 4speed would be like in the merit and star ect as the 5speed would be in the sr

[garyc]

4sp and 5sp are the same ratio, but they have a 5th gear.

There are also some rare 4sp clusters found in mk1 Astra's and the like which can sell for 250-600 quid......
