different 5th gears?

I average 32.7, Im sure I read that theres a 5th gear that does 70 at just over 2000 rpm? 

in an 8v? christ i was getting 42mpg in my old one!

yeh... although, if I drive a REALLLY long way on the motorway, I can get it around 40 mpg

I disagree.

I have an 0.75 5th gear cog in my AUG box. The standard one was 0.89, so the revs have dropped from 3500 @ 70mph to about 2800 rpm @ 70mph. What I've noticed is obviously a decrease in acceleration but an increase in mpg. Having spent 18 months travelling 90 miles a day (the reason for the swap) I recorded the following:
44 mpg @ 70 mph.
41 mpg @ 75 mph.
37 mpg @ 80 mph.

The revs (and power) are really too low @ 60 mph although the mpg is up near 50 or so.

The gear cog came out out of a 4T box. Mattneck has tried the same thing, although he was unlucky with his gearbox that broke. If I did the conversion again I would look for a 0.80 gear. This would give better economy (than stock) and a little more acceleration. Although having recently had her tuned she pulls well enough in 5th for me. Definately don't go for anything longer than the 0.75 though - you'd be going nowhere on the motorway.

Oh yeah, the box cost me £15 of ebay with a 1.6 engine attached to it, needless to say the rest went for scrap. As I was having my 2nd gear syncro replaced the dude just swapped the 5th gears during so it didn't cost me extra.

Motorway driving is a pleasure now, and much quieter...

do a quick search, i asked this a few years ago and got good answers.

I just never followed through on it, as i couldn't be bothered. If i crunched motorway miles, i reckon the savings would have been worthwhile

Searched again using your username, no luck again, maybe it doesnt go back that far? 

Im well up for doing it, I just wanna make sure I get the right gearbox to get bits out of.

Ah awesome, so are 4T boxes easy to find?  are they on any 1.6?

I'm not sure if they are on all 1.6L, the 4S has a the same 5th gear too. Alternatively if you went for a 0.80 cog, they are in CHE boxes which come out of mk 3 golfs so maybe more chance of finding one of them.

Just nose on ebay and here, someone somewhere will have one for sale.

A CHD box with a 0.75 5th gear. In Kent but if its cheap enough have it shipped.

They are about, hopefully a little closer than this one..

Just picked up a mk3 1.6 box for 25 quid. 
Is that a 0.80 yeh?
