In doing some research on the best gear ratio / transmission combo for my NSX, I came across something that looks pretty interesting. The 4.642 gears are even more extreme than Comptech's 4.55's. Since I plan on keeping my NSX an NA, these are very interesting to me.

Here are the prices based on today's exchange rate:
6spd gears + lsd = $2368.91
5spd gears + lsd = $2415.73
5spd gears only = $1151.69
6spd gears only = $1198.50
I'm not sure if the "gears only" sets will fit with the stock LSD or only with the OS Giken LSD. It also looks as though there is a 20 set limitation on sales? Maybe an OS Giken retailer can comment (SOS?)?
This 4.642 gear ratio produces the following shift points for japanese gear sets (in mph):
......5spd. 6spd.
1 - 41.54 41.54
2 - 65.10 65.72
3 - 90.52 89.90
4 - 122.76 113.46
5 - 178.56 140.12
6 - ....... 178.56
Can someone (i.e. Bob Butler :wink
do an acceleration calculation based on these numbers?
