I hear the Lancer and Evo share the same 5 Speed Tranny.. is that true?

If so, theres a 6-Speed Swap Kit available for the Evo.

If their the same, would it be benefitial to convert the Lancer to 6 Speed?

If so, what would be the benefit?

 

no benefit. lancers are too slow. unless you have like 500hp +.... but even then IX MR's swap for 5 speeds for reliability issues

 

The evo and lancer tranny are not the same, they are very different. For one, the transmission for the evo is designed to handle more power. It is also designed to work with the AWD (meaning it has a LSD built in if it's anything like the STI tranny among other differences). There is a benefit to having a sixth gear in the sense that you can keep the car in it's powerband longer and you can potentially have 5 acceleration gears and 1 cruising gear rather than 4 acceleration gears and 1 cruising gear (if that makes sense). The Nissan Versa has a six-speed tranny so it has nothing to do with power.

 

Nevermind the point that it's not possible. What would be the point? Our 4g94 has a very broad powerband. It produces good torque from just off idle up to nearly redline. Six speed would just slow you down shifting more.

If you notice, most cars that have standard six speeds are equipped with engines that make lots of peak power at a very narrow range. More gears lets you stay within that range longer.

For us, it's hardly a concern. Save your money and spend it on something worthwhile.

 

Not possible!

 

What, the 4G94 does not make good torque just off of idle, it's a freakin 4 banger not a V8, lol. If an STI can benefit from a 6-speed tranny, a lancer sure as hell can. The whole "shifting slows you down" argument only applies if A. you suck at shifting, B. the gears are horribly mismatched and C. you only care about drag racing.

 

I'm not sure you get it. I'm not comparing the torque of a 4g94 to a V8. But as four cylinder engines go, the 94 has a very broad power band. It's not "peaky" like a Honda engine or something like that, where you have to rev to 6500 to make power and then you redline at 7200. Our cars make most of their peak torque through a good deal of their usable RPM range.

The point of more gears is to keep the engine in its power band. Our power band is wide, so you don't need it. And yes, it will only slow you down. I don't care if you can shift in half a second, that's still a half second lost.


Think about it this way. My old car was a Focus SVT and it hardly moved before 5k rpms. 5500-6250 or so was the sweet spot, after that it dropped off, anything below that sucked too. So you would rev to that in first, but in a second, you're on the upper limit of that. So on to second gear and the same thing. It had a six speed, which was great for that engine.

Now take a lancer. They make close to peak power from about 3700 or so to 6k. That's a wide band. Fewer gears need.

Finally, think of an electric car. Electric motors make the same torque at ANY rpm. Assuming over-revving isn't an issue, how many different gears would be ideal?

One. Because you're in the power band the whole time.

Shifting slows you down, kids. If you want a shorter ET, you want to do it as little as possible. With some engines, 6 or more forward speeds is great. I'll concede that with a turbo, peakier cam and some very aggressive head, intake, and exhaust work, it may be better too. Those kind of mods will increase peak power but at the expense of a much narrower power band.

It's all a trade off. But I can tell you, even if it were possible, which it's not, 6 speed would only hurt you with a 4g94 in stock or near-stock form.

 

The 4G94 is still a 4 cylinder motor, it is naturally going to be peaky as far as power goes. If you look at the graphs, peak power is observed in the upper powerband. An easy way to understand this is to compare stamping the gas at 2000 RPM with stamping the gas at 4000 RPM. Any street car can benefit from more gears, why do you think Mercedes uses 7 gears in some of its transmissions? As I said before, if all you care about is drag racing, the less gear changes the better (some of the best drag cars had 4 or less gears) but if you care about autocrossing, tracking racing or driving on the street, an extra gear can be very beneficial. Hell even the corvette uses 6 gears and it has a torque curve flatter than Paris Hilton's chest.
For comparison purposes, here is a honda civic dyno (a b18a to be specific).

Notice how the torque curve is more or less linear.
Here is a lancer dyno, it looks very similar to the honda graph.

 

Oops double post.

 

We have terrible 1st and 2nd gear. Once you shift to 2nd the rpm drop too low.
1st gear is too short. and 2nd too long.

We need some mivec gears!!!

 

Is their anything we can do about out our gears? or make the auto's have a higher shift point or redline?

 

You could have custom gears made but that would be very expensive.

 

Very expensive.
