Just got this email back from Gordon:

You are definitely running a 14/53 (diff) and ratios approx
VXs were 19/63. Think it was the Trevi ies ran 18/65  sometimes/rarely found fitted
to Betas.
Your ratios approx after checking from marking
and counting input/output shaft:
1st- 3.5
2nd-2.3
3rd-1.55
4th-1.2
5th-0.92
R-3

Interesting observation about Trevi i.e. having the 18/65 gearbox...

As you can see the ratio was changed in 82 around the time that the ie was introduced in the UK, I'd imagine only first stocks were the old gearing but given the bad stock rotation of the time registration date might be a poor guide. However this is a different set of ratios to even later cars (it appears).

here are the figures from the latest (1984) technical book

No difference if its a Trevi, coup or HPE

I have to say that Beta technical changes are to say the least confusing!

Previous versions for comparison

I might check the microfiche if I'm in a real sad case mood one day....

It really does seem to be lap of the gods as to which ratio box you got, back in the early 80s. Every source seems to tell a conflicting story. And then there's the 'received wisdom of the day' which may or may not be correct.

With Beta stuff there is a lot of heresay which becomes 'fact' the only way to be sure is to trawl the official info. It still causes arguments though  Cheesy as people have their minds set for 30+ years. I possibly have more original Beta literature than anyone else in the UK, only possibly mind there is probably someone hiding away with more.... Anyone volunteering? I'd be interested to know

Reading with supreme interest!

My 84 2000 Carb [manu Dec 83] from Australia has a white plastic breather, but any other
markings,except "Australia" in red, are gone.

Many clues appear to show that the car was built up using i.e. parts in the main, such as
the radiator + fan, and the fuel pump although the dash binnicle is an early,'no-green' version,showing only km's.

I guess i'll only know what i've got inside that aluminium casing when i'm
able to drive it!

The 'ie parts' thing is more a case that we didn't get many late carb cars in the UK things like the rad and so on were changed for most versions possibly all but we didn't get them in the UK
