Taller 5th gear, where to get one

[Doakster]

Update:

Trans is back in, after a little bit of a drive here are my thoughts.

1st, 2nd and the lower part of 3rd have decent power, can't really tell much of a difference from the 4.25 ring and pinion.

4th, and 5th have a noticeable decrease in power, but not to much, just have to plan the shifts and rev a little more before the shift. Definitely doesn't have much pulling power on long hills and usually requires a down shift.

RPM sounds to be a little lower, i can't really tell because my ECO doesn't have a tach.

The bad news is i didn't see a mileage increase, in fact a little bit of a decrease, but I have other issues going on with mileage that i'm continually fighting.

If and when i put a Giles pump in, i will probably swap in a taller 5th gear, i think it should be able to handle it fine and drop the rpms a bit more in 5th.

You may be seeing your 43 mpg drop to 31ish because of the fact that you either need to be on the peddle wasting fuel, or downshifting and revving the piss out of her for more power.. I mean probably not 10mpg worth.. but possibly a good factor.

The mileage drop occurred some time well before pulled the trans and swapped final drives. I had been driving the car with poor mileage for months before the trans work. Before the trans was pulled i was getting 32-33ish, and after the trans work I'm getting 31.5ish. My mileage battle continues.

You and me both!!  I've got a super tall transmission but my mileage numbers are right around the same as yours.  Doesn't seem to make a lick of difference where I tune everything, my mileage is suuuuper consistent.  At most I can squeeze an extra 50 km out of a tank by being really easy on it...
