RE: RS2 Engine and 6 speed tranny for sale

you should remember that there are a number of different audi 6-speed boxes.
two revisions had different ratios, for the a6 (diesel) and also the s6,
while the s2/rs2 and s6+ had the same ratios, and the same gears and
bearings.  there are also differences with the casings between the various
models.  hence the transmissions themselves have different part numbers.

rs2 01e 300 043p
s2  01e 300 044k
s6  01e 300 042n
s6+ 01e 300 044p

also, despite the post which stated that the ratios are the same, they most
definitely are not with the s6 box (which blau is trying to sell - i wish
they would get the part number right at least). the s6 tranny is the most
different, with a range of ratios available with 1st (3.5, 3.55), 2nd (1.84,
1.86, 2.11), 3rd (1.23, 1.32), 4th (1.07, 1.03), 5th (0.730, 0.757, 0.806,
0.857) and 6th (0.684, 0.730).  the driveshaft also has the choice of 2
ratios, 1.14 and 1.10.

the ratios in the s2/rs2 and s6+ tranny are the same with 1st 3.50, 2nd
1.89, 3rd 1.32, 4th 1.03, 5th 0.857 and 6th 0.711, and the driveshaft 1.10.

so, it seems to me, that it would be possible to build a "short ratio" box,
using the appropriate gear clusters from the s6 box in your eratsz s2, using
the s2 01e tranny.

also, it would mean that you'd want to do a little more examination before
buying that blau box.
