I was just wondering if anyone know what the gear ratios are in a 5spd 2002. See i absolutely hate the 5th gear.. i want to get a new one to get my car down to a bout 2000rpm at 70mph. so i need to know where we are stock.

from this link: Hondanews.com > Honda > Civic > Specifications

2002 SEDAN final drive ratio:
DX/LX = 4.111
GX/EX = 4.412

2002 COUPE final drive ratio:
DX = 4.111
HX = 3.842
LX = 4.111
EX = 4.412

spec sheet also lists ratio per gear for 5sp if you need those details

So what needs to be done can we get the final drive of an HX into an ex and make ex go faster???

It is my understanding that the HX uses CVT trannies not tradtional gears.

Explanation... on How Stuff Works: CVT

i would think that 2k rpm at 70 mph would be wishful thinking due to the lack of torque...but a slightly lower final drive would prolly lower your rpms a bit. maybe a custom grind 5th gear would be your best bet.

don't take my word for it though, i'm just a n00b

What about a different camshaft ?

nope...you need to do some searching on this topic. Not many will be willing to answer such random questions...

and believe it or not 3500 rpm really isn't that much for our civics man....they're built for fuel economy, not speed. remember?

im actually looking for more fuel economy.. my friends saturn sc2, is at 2100 at 75ish, and our HP and torque numbers are comparable.

i dont know if its just me, but i can "see" my gas gauge go down as soon as i get to freeway spd (70mph in MI) let alone trying to pass... i was just curious what it would take to help this

HX can be had with a CVT or a 5 speed manual with tall gearing aimed at high fuel economy

So we can we put an ex final drive of 3,842 to an ex an earn maybe a second or so to 0-60mph maybe...
