6 Speed

[Maitre_Te_Te]

Hello
Anybody have try to put a 6 speed transaxel on 1nz-fe?

[1.5]

too much money for something so unnecessary.

[kngrsll]

its been talked about... ive debated giving it a shot. if you are serious, there is a 1st gen vitz that has done it using the 6spd + LSD from the blacktop 4AGE engines. Id look into what he did and go from there.

[thebarber]

from what i understand, the 6speed from a 4age will bolt up

c60 from a gt-s/xrs wont fit, but i was talking to a toyota tech last month, and the gears will fit in a c54 (i think thats what it is, maybe a c50)

[Sidicas]

I've heard the Ford Fiesta Hatchback has 6 speed.

I think the OP's question is answered, which is that one guy with an Echo mated a 6-speed to a 4AGE.

My question is what is the advantage to a 6-speed on this car?

[1.5]

thanks garm thats exactly what I posted lol.

Very expensive with little to no benefit. You might shave a tenth of a second on acceleration due to more torquey first gears and u might get 1 or 2 extra mpg in 6th gear but really worth the couple grand to find, buy, modify (if needed), and install the damn thing? I dont think so.

well, given the the powerband is pretty linear in the this car, i would imagine just to have closer gearing to stay in whatever piece of the powerband you'd like more easily?

lower 6th than the yaris's 5th for lower rpms on the highway?

[1.5]

yea those are benefits but we're just saying that they will be very slight to notice and its not really worth the large amount of money this project would require.

[Kongo-Otto]

Maybe the new 6 speed gearbox seen with the 1NR-FE engine could work. But i doubt its worth the effort.

omg transmissions are the most complicated parts. ^^

[yaris2010RS]

i thought of this idea (for about 1.2seconds) cuz having a 6th gear is a cool idea, but really i agree, not worth time, effort or money.

[Bluevitz-rs]

For anyone that ever goes to the track, the 6 spd is TOTALY worth it. And revs would be HIGHER in 6th on the hwy. My parents have a XRS with the 6 spd and even with the tires being a lot bigger it still revs higher than the Echo in any gear.

For comparison...

That's a massive difference in acceleration.

good stuff, i figured you might pop in at some point

[yaris2010RS]

thats kool, but would the yaris (or vitz) be able to hold down the extra acceleration to the track? i know slicks (orjsut supper soft compounds) would be in order but even that wouldn't it be very very difficult?

[Bluevitz-rs]

Yeah echodriver.com is getting a little slow. I used to be on here more often until my account got hacked :mad:

[Kongo-Otto]

Hm my revs with the 6 speed are definitely lower on the Autobahn. That was the main reason for Toyota to introduce this gearbox here. More fuel efficiency. But i am sure i dont have a C160. Must be something else because its very new.

[thebarber]

id imagine it depends on the final drive you've got in the transmission. i thought wikipedia showed that the 6th gear in the c60 is lower than the 5th in the yaris

[Kongo-Otto]

Tech data from the new 6 speed:


1.33 Dual VVT-i 1NR-FE

6 speed gear ratios

1st 3.538
2nd 1.913
3rd 1.310
4th 0.971
5th 0.818
6th 0.700
Reverse 3.333

Final 4.055

The C64 has the same 6th gear as the C150 5spd. Both .815, but the C64 has a 4.5 final as the C150 is only 3.5.

The C64 is used in the Lotus and I think the Corolla XRS. But all other gears are the same.

I remember driving a '03 Yaris RS (Puerto rico spec.) that has the C152 in it. Same gears as the C52 from the '00~ Celica GT. With a 1.904 2nd gear and the 4.058 final you could do a burnout starting in 2nd.

The C160 on the other hand has an even low 2nd gear and lower final. So I can only imagine how a hard launch would do from 2nd.

Edit: Oops, went on a little rant there. Yes the C60/160 does have a higher 6th to the Yaris 5th, but the final is so much lower on the C60/160 that the end result is still more revs at the same speed.

Hello
Anybody have try to put a 6 speed transaxel on 1nz-fe?

I own the C160 6psd transmission mated with a 1NZFE turbo. The gears are close ratio and it keeps on reving much more than normal 5spd trans.

When launching with high throttle the 1st gear complete in almost 4sec and 2nd gear in almost 2sec. Infact during drag races I usually launch with 2nd gear since it's pretty low aswell.

The main reason I installed the C160 since the trans is capable of more bhp compared to the C54 (stock one) and because it has the Limted Slip Differential.

Why would you need a 6spd trans?

well yes, the final drive is different so you'd have higher rpms on the highway....but i was talking about removing the gears from a c60 and puting them into a c54 housing (or whatever the code for the yaris tranny is) so you could keep your stock final drive and use the c60 gears...

would that work? c54 final drive w/ c60 gears in a c54 bell housing?

I just remembered that I had previously looked up both input and output shafts between the 5 spd and 6spd and they are totally different. Also, the final drive gear is part of the output shaft.
