    Hey guys and gals,

    So this is my next project that will take place next week. These gears will replace the stock 4.10 gears. They came from a Kia Sportage actually and work out to be a 4.77 ratio. This should make it a little more fun to drive around town, especially with the lack of low end torque Honda is so famous for. Top speed is reduced from 160 or so to about 147, but thats ok with me. Its no Z06 or 1k whp Supra, so im ok with that. I also got the "Yellow Box" speedo calibration kit so my speedo wont be off. A good driver can shave off a half second 0-60 and 1/4 mile. It should keep up with a base 7psi Comptech supercharged S2k until top of 3rd gear. I will let everyone know how it goes.

    So, since I'm learning all this fun stuff. What does changing your gears actually do to your car? I keep thinking shifter gears here, but I'm guessing that is incorrect :p

    This is the final drive gear in the differential. This is a shorter final drive gear, so it acts as a torque multiplier. Kinda like riding a 10 speed bike and trying to take of in the 10th gear vs taking off in the 5th gear. You will accelerate faster in the 5th gear but will have a lower top speed. It sort of acts that way. Pros: faster acceration (.5 seconds faster 0-60 and 1/4 mile) cons: shifting more, top speed reduced, higher cruising RPM's on the highway. Here is a video to give you an idea. Both stock S2k's. Camera car has higher gears, the silver one has stock gears.

    Ah. I think I get it :) This kind of stuff, is something I wanted to look more into since I would love to make my first gear a bit longer. Maybe a weird idea, but I can't go anywhere before i have to shift to second, and it bugs me :p
