Hello-
Just one quick point: the later boxes do _not_ necessarily have "better" gearing. It all depends what you want.
The 3rd/4th/5th gear selections changed for the various 915 boxes, but the 1st stayed the same. As a result, the overall 5th ratio for the late and early boxes are very similar. The difference is that the spacing of the later boxes is closer, and the 1st gear is significantly taller. While the first point is definately good, the last one might not be.
Let's look at some comparison numbers for 1st:
Early VW box with 4.12 R&P: 33/8 x 38/10 = 15.68
Late VW box with 3.88 R&P: 31/8 x 34/9 = 14.65
Early 915 box with 4.43 R&P: 31/7 x 35/11 = 14.08
Late 915 box with 3.88 R&P: 31/8 x 35/11 = 12.32
More isn't necessarily better...
Case in point: in my Fastback, my redline is going to be 9000rpm. The last thing I want is a really tall 1st gear! I'll accelerate better with an early box. Add that to the fact that my early box is a 923 (easy fitment with T4 components since it was on a 912E) and I have a winner.
Take care,
