[SPAM] Tranny Selection

Not the same - 2H final drive is 3.89 vs. 3.67 for the 2Y.  Also the 2H
can't be converted to accept Peloquin shim/spring kit.  

I thought the 2H was 3.94:1 and the FK was 3.89...

The 2H uses thinner seals, but the shims will work.
40% is easier, because you would have to machine the case to accept 100mm
CV's, which are required for the 80% kit.

IMO 1st gear will be useless, as it is on my MkI/2.0L 16V and 3.89 f/d
4-speed.  I can punch it at
nearly any speed in first and break the tires loose, and that's *with* a
Quaife.  I'd go 3.94 or
3.67.

Then go 3.67 with a medium/close gearset.

The 2Y part, yeah probably.  For 5th, I'd go no stiffer than a 0.80.  IMO
.71 is just tooo stiff
and a way big jump from 4th.
