i have a 96 ex coupe. (s40 trans)

i have an s20 sitting in my basement waiting to be put in my car.
before i do that however i am curious to see if i can do the following:
take the 4th gear and final drive out of a 7th gen (2002 EX)
the gear ratios are:

mine:
3.250 1st
1.909 2nd
1.250 3rd
0.909 4th
0.702 5th
4.250 final drive

the 2002 ex:
3.143 1st
1.870 2nd
1.241 3rd
0.970 4th
0.757 5th
4.412 final drive

1st - 3rd i don't want - but 4th, 5th, and the final drive are shorter.

i'm not looking for a huge difference here - my car is a daily.
however i want it to be just a little quicker.
so the question is:
can i swap these gears? will they fit?

Honestly, I don't know. I want to say no. I will say though that if you can find a '92 - '95 CX/VX trans you can use 3rd gear from that as a short 4th in an Si trans.

that's interesting... i didn't think you could do that. (swap gears to other gear slots i mean)

stallinrawlings

are there other gears that i can do that with? cause i haven't started this yet, so i'm doing my homework haha

It's just 3rd and 4th you can do it with. The reason being they share a common sleeve and hub, and both halves of the gearset can be removed from the shafts. Besides the ratio 3rd and 4th are identical in their demensions. You could do the same thing with 1st and 2nd if the mainshaft gears weren't cast as part of the mainshaft itself. Not that it would really help you any, All '88 - '00 D-series transmissions use the same 1st gear so it's not like there was a long 1st gear you could use as short 2nd.

yeah. I just built a single stick trans with mfactory diff and vx 3rd for fourth

so now my question is this:
what's the best/easiest way that i would acquire such a fine piece of hardware. (O.o)
lol

stallinrawlings

cause if possible i'd rather not buy a whole other transmission...

94EG8

You can see if Synchro-tech or Gearspeed have any new or good used gears or you can buy a used transmission (usually the cheapest option as long as you get one with a good 3rd gear)

The third gearset is discontinued from Honda so you can't just go to your local dealership and order it anymore like you used to be able to.

stallinrawlings

sucks about the dealership - but that's how it is for a lot of stuff now with 90's honda...
i'll check, thanks so much man, time to get to work.
