^well i was saying that our 5speed trannies bolt up to the 4g63 block........no sure if thats what your questioning. im sure theres a lot of work getting a 6speed in our cars.

 

Can you just replace fifth gear with a bigger ratio for better highway miles? I don't get out of forth when I'm driving aggressive anyways.

 

Should be possible. The issue would be finding another transmission with a more favorable ratio to steal gears out of. I'm really not terribly knowledgable about transmission internals and what things can/can't be swapped.

 

is it just me or do our 1st gears seem really short..... but instead of a 6 spd how about upgrading all of our gears to be a bit longer??, just a thought, probably not possible, but cant hurt to think about it. and sorry to thread jack

 

You are right.....check out the RA's gear ratios (manual trans.). Pulled this from the service manual.
1st: 3.583
2nd: 1.947
3rd: 1.379
4th: 1.030
5th: .767

Oh.....and FYI.....the reason why dynos are run in fourth gear: it's the closest 1:1 ratio that the RA has. So for you guys running on dynos in 3rd gear.....stop.

IMO, 5th gear is fine on our car. If you want to save gas, slow down.

 

that's why you don't have to use 6th gear at low speed, you have choices on what gear to use. 6th gear for highway is def. useful, who told you to used 6th speed when cruising 40mph around town?
To often on playing w/ clutch, come on man, don't exaggerate, just one more gear!
I love the 6 speed on my MR, I have more gear selection, higher top speed, better fuel economy and faster re-acceleration on the topend. the 6 speed in a civic si is very closed ratio, I don't like it, but oh well they have no torque. s2000 is another example.

 

Its funny, in the Evo side the MR guys that track get rid of the 6sp for the stronger 5sp.

Its about gearing.

This is a commom misconception in the Evo world. Our 6sp does not act as an overdrive gear. It does not drop the RPM that much on the freeway either.

I like the idea of doing a different 5th gear - basically making that into an overdrive gear.

 

6th gear in my Evo IX would be great... 80mph on the highway all but tachs 4G. Great in the powerband and pulls strong in 5th from 55mph on up... MR 6 spd would be nice though...

 

each gear box is geared toward the engine power band. if you make each gear longer you'll lose acceleration but gain top speed. why do you need more top speed especially in a Lancer?

 

the 6 speed in MR drop only about 100 rpm compare to 03-05 evo 5 sp and more compare to IX 5 sp. 6 sp offers more selection in a road course and better topend acceleration. for ex. when a 5 sp evo racing a 6 sp evo, when both car running at the end of 4th gear, shifting into 5th gear in a 6 sp evo vs 5th gear in 5 sp evo, the 6 sp evo will have better advantage.

I dunno why in US people have problem with 6sp, in Japan 6th sp are fine all over the tracks.

 

I you want a better fuel economy gear ratio for our tranny I beliebe we could take the 5th gear from the outlander.
Looking at the numbers the 5th seems more for overdrive than tork compared to ours

 

The Outlander is definitely geared way different. My wife's '06 is an auto (4 speed), and cruising the highway at 70 it's just tickling 3k RPM, IIRC.

edit: and it has the same engine as the RA, in case some of you didn't know. So there are 2 4G69's in my garage.

 

is there not a final gear in the tranny to be swaped out for an all around change in the ratios??

 

ok so i rode in my buddys gti the other day and ya cruising at 70mph in either my car or his, both of our cars are running about the same rpms. so gas milage wont be much or if any different. but it would be nice to have more available torque throughout the gears

and i didnt mean make them significantly longer, just a little longer. to me 1st gear is way too low, so from a stop light in traffic (not racing) im always 1-2 car lengths behind everyone before i shift into 2nd. k well i take back changing all the gear ratios, just making 1st gear longer would satisfy me. and ur righthaha who needs top speed in a lancer

 

The RA's gear ratios were meant to be close which is why when we upshift in every gear, the revs drop to the same level unlike Regular honda civics (for example)which have their 3rd gear quite longer compared to 1st and 2nd.

The problem with just changing one gear is that it would affect the usefulness of our other gears; for instance if you make 1st a little longer (say up until 40mph @redline) then with our 2nd going up to 57mph +/-, you may as well just skip 2nd gear altogether and throw it into 3rd as you will lose to much time upshifting twice while having almost no acceleration through one of the gears.

I say that your best bet would be changing the final drive to something less agressive like a 4.00 or even a longer 3.89 ratio (if there is one that fits in our tranny, it will probably cost a ton plus installation).
