Another quick question.
AFAIK there are 3 types of F20. Which model/s did the longer 5th gear ratio F20's come from?

1, f20's what? No need for the '.
2, never heard there are 3, i've had cav and Astra ones and they've all been the same.
i think the 4x4 F20 had a strange FD
F20 W5a 3.55 2.16 1.48 1.13 0.74 0 3.55
F20 W5b 3.55 2.16 1.48 1.13 0.71 0 3.55
F20 WR (dosent exist) ?? 0
F20 CR 3.55 2.16 1.48 1.13 0.89 0 3.72 3.55 3.42
1st, 2nd, 3rd, 4th, 5th 6th and FD(s)
Thought there were 3 types all with the same 1-4 ratios but different 5th speed (so I've been reading over the years).
Was just wondering as the slightly longer 5th gear would be good for motorway driving, less noise, increased mpg and all that.
What sort of revs does the common F20 do at say 70mph?
F18 WR for the high end 5th
Erm 8 gears?Quote:

I don't get how you get 3 final drives...
before the 0 is 1-5 the 0 is 6th (ie non existent) and the numbers to the right of the 0 are the FD'sQuote:

3.72 / 3.55 / 3.42
3.55 is the most common one, i've got one of the other's in the garage, but can't remember which one it is tbh, iirc you can tell by the rings on the gears..anyone know?
Mazz, I'm after the 3.55 you willing to sell it?
PM me :thumb:
I still do get it.Quote:

I've got either a 3.42 or 3.72 from my old box, the 3.55 is in the car now! They are the most common ones, PM Iainel - iirc he had a few damaged F20'sQuote:

I haven't got a box. Looking for one and I'd preferably go for the slightly longer 5th. If the 3.55 final drive are the slightly longer ones then that's what I'll go for.
Ah ok, wont 3.72 be longer?
It will be but I don't want it to be super long, but again not too close as I've suffered with high revs on the motorway in the NOva with it's F10 lol Just want it in the middle.
5th is different in all 3 F20'sQuote:

Then i really don't get what you've put up there at all.Quote:

but the left most number after the gearbox name is 1st, then 2nd then 3rd then 4th then 5th then there is a column for 6th which is 0 in this case and then its the Final drives.
easy
But why is 5th and the final different? Surely they are the same gear?
I'm on my second F20 and this one is out of an SR 130, can't tell the difference
No.Quote:

Perhaps a look at howstuffworks or wikipedia will help.
(think of it like a RWD car that has its gearbox upfront so 5th is in there it spins the prop shaft and turns the diff. the FD is in the diff)
Ah ok i get it a lil more.. Cheers.
