Just wondering if anyone has endevoured to install a modern 6 speed box in a Celica yet?
Doesn't seem to be any info around, just curious. -------------------- Mike W

Why did anyone ever make a 6 speed? To have more driving gears and therefore, higher gearing capabilities. I'm just slightly confused by what you're wanting. You want, and I'm making this up for the sake of having numbers, a top speed of 150. You can have that with the E153, or you are trying to make your own 6 speed that will also do 150, but with more shifting. You would lose time every single time you change gears, so I'm just confused by what you're looking for. Hypothetically, you might make it to 60 faster, but you also might not. Depends on how much time you lose when you shift.
As I understand it, there is X amount of room within the transmission case, and those 5 gears take up every bit of that room. No extra space for another gear. You CAN have 6 gears in that transmission case, but they will have to be custom gears. It sounds to me like you just need to decide what ratio you want each of your 6 gears to be and then have them custom made. -------------------- "Employ your time in improving yourself by other men's writings, so that you shall gain easily what others labored hard for." -Socrates.

It sounds to me like you just need to decide what ratio you want each of your 6 gears to be and then have them custom made. i probably will need to have them custom made... and what i'm attempting to gain is closer gear ratios to allow for faster acceleration, rather than a higher top speed (though that would be nice, i'm not too worried about top speed with the 3S-GTE)... as far as loosing speed on shifts, i'm planning on having a short shift kit, keeping the RPM's up, and the clutch i have should engage pretty quick... i'm not too worried about loosing time on shifting because of the build i have laid out... 9.4lb flywheel, 6 puck carbon-kevlar clutch, and a high-rev engine (all the bolt-ons will help get up there quick too with a light flywheel)... i should loose the same amount of time shifting with this build on a 6 speed as a 5 speed, just with an extra shift, yes... but that difference would be so minute that if i get the gearing JUST right with the 6 gears, that the downsized gears would more than make up for the loss of time on the one extra shift before my top gear (at which point shifting is the least of my worries with loosing time)... balance i accept = shifting sooner < vehicle being more responsive and getting up to speed quicker way i see it, shorter gears is like a lighter flywheel in the long run... reason i want a 6th gear instead of just a shorter 5 speed is to not weaken the power curve in the top end in higher gears, as well as maintain the same top speed and fuel economy, but get better acceleration at the same time. basically keep about the same higher gear ratios (6th gear would be a little longer than the original 5th)... the first 3 gears would be closer, and 4th would be a little shorter too... 5th would be slightly shorter, and 6th slightly longer. less rotational inertia to start/speed up, stay in the optimal power band still, and maintain nearly the same top end...  that's really what i'm going after here... besides, you can't really argue that a 6 speed gen6 awd race-tuned celica would be one sexy beast!! viper: 6 speed. corvette: 6 speed. lamborghini: 6 speed. sorry if that got repedative, if my spelling is a bit off, etc... long LONG day today, and another long day ahead tomorrow... looking forward to more responses. |
