Hi, all.
I don't think I've ever seen so much traffic about this subject in such a
short period of time. Anyway, here's a few observations: I know of a
fellow in England who saw a Celica 5-speed fitted to a Herald in
Australia, and did it himself, if I remember correctly. Not the Supra
box, it's too big. As for the NZ conversion, IMHO the cost doesn't
justify the benefits. I don't consider a .86 fifth gear as all that
usable. In a past issue or the Courier magazine, there was a letter by
someone who had a 2.9 diff made up for his Spit 6, and fitted it with O/D
(4th-O/D ratio of 2.32). He was turning 2300 at 70 in O/D top. At a
local track, he reported turning 4000 rpm down the straight (approx 121
mph). The point is that the 6 certainly has the torque to handle a
considerably taller overdrive ratio than any of the alternatives (or the
factory O/D). Now, if Toyota were kind enough to supply a .65:1 ratio
5th gear set for the 2T box...for the Corolla, with it's little 3TC?
Even the Rover box is only .83:1. There doesn't seem to be a compact
'box with the nice tall fifth, which is the point of all this trouble and
expense. Anyone know who can cut gears cheap?
