Zac,
The most common method of making a close ratio box is to have new gears
cut, then machine the counter-shaft down and weld the new gears to the
counter-shaft. There are a lot of people who can do this work but the price
works out at approximately $650/gear (ie $1950 for fist second and third
gears) Thats why option boxes are so dear.
Often you can change overall drive ratios by changing input shaft gears and
countershaft gears (ie 22 drives 31 used in most Nissan later 5 speed boxes
to a 240K 4 speed gear set with 21 drives 32) this used in a 240K 5 speed
gives a very useful overdrive of 0.92, but first is useless and there is a
big gap from second to third. So the first three gears need to be recut.
There are a number of ratio options available using different input gears
and countershaft gears. You can even have a stump puller 4.2 first if you
want.
Cheers
Feral Errol

List, whats the possibility of building our own close-ratio boxes?
I have heard of people sticking bluebird gears in an SR20 box to get a
lower
1st gear...
