Who knows if the www.ikeya-f.co.jp seguential shifter is compatible with USA and European FDs ?
Thanks.

 

I think it is. It also comes with the standard ladder to reach the frigging handle. Why would anyone want that in an FD? That's weak sauce man...if you're really interested in going to a sequential shifter, get a sequential tranny.

This shifter keeps floating around in various threads, and I'm sure that it probably qualifies as one of the lamest looking things you could do to your FD.

 

o.k but the seg tranny is very expensive !

 

I here that works very well in left hand drive and right hand drive and are very quality units. I do agree that it is too high above the console, but think it would be great in something else that is lower in the dash. Still more than I would want to pay for that.

 

Shifters for seq trannies are typically high. They are high because the driver has both hands on the wheel at all times and only needs to touch the shifter when shifting. The shorter the distance to it, the better.

There's no substitute for a real seq trans however.

 

Given that car sequentials (i.e. not motorbike or jerico) use a barrel to select gears this would appear to be exactly the same working principle, except its external.

Best done with a dog box of course, but that's not a bad option. should be worth a 10th or 2 on the 1/4.

 

Exactly. The sequential shifter is not going to shift a synchro tranny any faster; the synchros physically limit the speed of the shift. Only thing worth doing is using a dog box if you want to go sequential.

 

JT-Imports carries the one from Stillway. It's half the price of the Ikeya and looks like a stock shifter when installed. I'd go with one of those. With a boot installed with it, I'm sure people would have a ball trying to figure out how to drive the car.

 

Her's another one... I don't know what to think of this thing. But a sequential tranny...now THAT would be sweet!

I'm surprised no one has mentioned one important fact.. You still will have to use the clutch pedal.. This isn't Sequential in the true sense. I first saw this product about 2 years ago so it's been around for some time.

 

Exactly. An absolute waste of money without a true sequential "dogbox" transmission...

 

Biggest drawback to a sequential is you have to always go through all the gears. Driving along in 4th and want to stop and go to reverse? You have to shift down 3rd, 2nd, 1st, then reverse. You can't just stop and pop it into reverse. It's even worse with a dogbox. To shift reliably, you have to be moving. Kinda like my motorcycles.

 

O.K but with this seguential shifter its impossible to lose the 3rd gear specially under pressure ( drag racing )
I have see many racers ( Ari , for example ) to loose this gear and some times the victory !

 

I have one. It's impossible to lose ANY gear. Yes you have to push the clutch down. I shift "mad quick" now with confidence....I'm not going to miss any gears.

 

What's a "dogbox"?

Victor

 

no good for LHD because of the way it mounts the leaver. Jspecracer has one in his whip. which i have a pic of (because it owns me). it is hardly useless, of course you have to use the clutch, it is called a "sequential shifter" not a transmition. no, you would not want a dog box for the street, it would eat itself and grind all the time. this shifter makes it impossible to misshift.

 

gah took me so long to U/L that jspec already posted, lol. anyway, a "dogbox" is a tranny that uses "dog teeth" instead of sincro's. it simply slams from gear to gear.

 

A synchromesh transmission uses "ring" gears with small teeth on them to align the selected gearset, which are usually (but not always) cut in a "helical" fashion, meaning the actual gear teeth are curved to allow them to synchronize/mesh at speed easier and quieter.

A "dogbox" is a transmission with gearsets using "engagement dogs" instead of synchro rings; in a basic sense, instead of using small teeth to align the gearset, they use large pegs/slotted holes. And the gear teeth are usually straight cut, which usually allows for a stronger transmission (but a much noisier one).

The biggest advantage of a true sequential dogbox is that it can accomplish full throttle/clutchless upshifts that are far quicker than any manual synchromesh transmission can accomplish (provided you have a way of momentarily cutting engine power, usually through the ignition), and downshifts can be done without the clutch as well. Motorcycles have been using dogbox transmissions literally since day one, but they can get away with the noise and engagement differences, since their transmissions are microscopic compared to the size required for a car.

 

Who sells this shifter in States ?

 

Hey guys,

I know this thread is a little ld, but I wanted to ask about the Ikeya SS. I no longer have an FD, and now have a Civic CRX.

I remember Ikeya had future apps for Civics and Integras and I wanted to ask some questions about the setup. Has anyone thought about trying to modify cluth cable so that you can operate it with a lever on the shifter?

There is a guy at my work who used to be in a pit crew for a team that used go-karts powered by bike motors. He mentioned that these karts used the factory sequential transmission. He said that they were operated by the shifter lever in the cab which had the forward to back motion to shift. The tranny's still needed to have the clutch operated so they mounted the clutch lever right on the top of the shifter handle.

Doe anyone know what I am talking about? I dont think like this has been attempted on a street car. This idea just came up because I saw a vid of a EscortRR with a 900CBR motor and factory tranny in it. I liked how fast the car shifted, so then I started thinking about adapting a motorcycle tranny to a Honda D or B series motor (far-fetched I know). Then I remembered that Ikeya had FD and possibly Honda apps coming up.

inputs anyone? for the techies, do you think it would be remotely possible to modify the Ikeya shifter (FD or Honda cable tranny) and clutch like I was talking about?

Thanks

 

You could run a cable operated clutch to the shifter handle and so operate the clutch with your hand while you shifted.

Now think about how long the clutch pedal on a car is and how much travel it has. You're going to have to have superhuman strength to even hope of operating the clutch with your finger strength. Ain't gonna happen.

A motorcycle's pressure plate does not have near the clamping force of a car's, so the motorcycle clutch is much easier to operate.

A motorcycle tranny isn't going to be able to work in a car. Even though motorcycles make lots of power they are not near as heavy as a car, so they don't have to account for near the load. A motorcycle tranny would never hope to live in anything but very small and light formula type cars.

 

Yup that was one of the things that I thought would be a problem.

How much lifting force does it take to operate the clutch mechanism on most cars? say for example on a cable operated Honda B16 Transmission (Y1 or S1). And I'm sure the amount of force required is more for hydro trannies and higher end trannies?

My solution to overcoming this problem would be a standalone electrically or hydraulically driven actuator which operates the clutch mechanism and controlled on the other side by the squeeze mechanism, but which would not require as much strength to operate. Does that make sense?

Basically the squeeze mechanism on the shifter is connected via cable to a custom actuator on the input side. On the output side of the actuator, it is connected directly to the tranny/clutch lever and the output side of the actuator has enough strength to operate the clutch mechanism.

 

Use a actuator of some type that is controlled by the button then the actuator actually pushes in the clutch. I believe you can get hydrolic ones. Or maybe they were air? I cant remember. I was checking out this go cart with a motorcycle engine that had a (I think it was air) air shifter that was push button on the steering wheel. It operated the clutch and everything all with one button. But I dont know if it would work for our application and I dont really know anything else about it.

That would be bad ***

Hmm, do you think either of those require an external power source or could they be run off of the car? I said electrical because it seemed like the easiest to find a power for, but I'm guessing it would be the most prone to failure.

I would think that any actuator would work as long as it is compact enough and it is able to multiply the cable pull that your finger generate, into a force great enough to operate the clutch mechanism.

You are right though, it would be bad ***. If this was made to work along with the Ikeya shifter you would have a very close imitation of a true sequential tranny. Instead of operating the foot clutch pedal you could operate one on the shifter with your hand.

 

An "air shifter" for motorcycles does not actuate the clutch; it only cuts the ignition and activates a pneumatic pressurized cylinder that pushes on the shift mechanism to accomplish the upshift at the push of a button. Motorcycles use sequential "dog boxes" that can change gears without the clutch.
