Which transmission with 4:10 gears?
I was thinking 6 speed but seems like 5 speed will be much more driveable with 4:10 rear end. what are your opinions?
im looking to replace my transmission as second gear synchro is going out. |
stay with the 5 speed. you are never gonna have enough power to need the stronger 6 speed.
|
6 speed. (so when it comes up for sale in the future I can buy it)
|
5 speed it is then :)
|
6-speed holds value better. ;)

did i ever tell you guys that you are complete assholes? :)

Have you seen the gearing calculator?
http://www.flyinmiata.com/tech/gearing.php 1st gear + 4.10 + 205/15 +7200rpm = 38mph w/5spd... 32mph w/6spd. More importantly, I'll quote the numbers for my favorite gear... 3rd. 5spd= 90mph 6spd= 73mph Have fun shifting twice as much if you get the 6spd... guaranteed that shit will get old quick. If you were running 3.636, different story. |
Late model 6 spd including MSM use 4.10 final drive from factory.

i think ill go with 5 speed. gearing seems a bit better for track. i dont like to shift very often. plus, if i ever want to shift every 5 seconds, ill take 350z out :)

I love my 6 speed, 4:3 combo. Forget how short first is, it is only to get rolling, I never use it otherwise, the other gears just have a much better geometric progression in comparison the the 5 speed, and I never need to go faster than 210(7k rpm) so the top speed of 6th being a little less is not a problem either. I think of it as basically a cheap option for close ratio box.
Just to give you an idea of how great the ratios are for the track, this is a video of one of the previos trackdays when the car had fairly stock 1.6 engine(just cams which don't gain that much) and the 6 speed with 4:3 and fairly slippery tyres(hence the half spin) mine is the white one and the cam is mounted on a stock 96 spec na8 with sticky tyres. The ratios allow the engine to operate around peak hp more of the time, hence being faster with the same power. http://www.youtube.com/watch?v=7GdPXJporso Just my 2c worth, Tim |
