I was hoping there would be some sort of update by now on a six speed manual transmission. I have hear that ZPI was supposed to make one, but I guess it's up to someone else..? So, if there were at least a choice of gears to install in our current gear box that would be great. This is some info I got on ours cars.. If anyone has an update on this please hook it up with a reply.

Gear Ratio Overall ratio (Rpm) Mph
1st 3.54:1 14.98:1 (6200) 31
2nd 2.05:1 8.66:1 (6200) 53
3rd 1.33:1 5.65:1 (6200) 81
4th 0.97:1 4.12:1 (6200) 111
5th 0.78:1 3.28:1 est (5650) 127
Final drive ratio......................................................................4.24:1
Engine rpm @ 60 mph in top gear.........................2700
Engine rpm @ 92 mph in top gear.........................4000

 

so far no other gear boxes or ratios fit out tranny (as far as i know). i think the closes u can get to something different is the final drive out of a rav 4 or a solora but neither are big improvements. zpi....well ____ zpi

 

rav4 or a solara, that's a good idea. What I would like to do then is replace my 4th gear with my 5th and use a final drive from a solara.

 

How much would that cost? Is it hard to do?

 

go to a junk yard, find a manual gearbox from one of them. rent a gear puller, take ur gearbox apart and switch. i havent done anything like this my self but thats the basics of it

 

watching

 

thats alot of work for one damn gear.. didnt some celica come with a 6 speed? switch bell housings?

 

They don't line up. There was a man who researched swapping out transmissions and there isn't a single one that'll work. The closest he got was an MR2 6 spd but close doesn't work very well!

 

hmm... I wonder if anyone has done this before???

 

i think garage1217 mentioned something about maybe putting taller gears in his turbo tc, but i haven't heard anything else about that from him.

 

There has to be something we can do.
My friends little civic does about 3000rpm on the highway.So why can't our cars do that.
I know My Tc makes more power than his.... Well, when we were in my car on the highway he said, "dude change gears!" and I had to tell him this is the curse all Tc owners have to deal with. WTF

 

How hard would it be to drop the celica 6 speed transmission guts into our case and bolt it up? It would be some work, but if me and my uncle can put a ford rangers tranny in a 5.0 case i think it would be possibly.

 

I think that would be cool, but the Japs aren't known for making interchange parts like the American cars. But if that worked, I would gladly take the bus for a while until my car was finished.

 

someones bound to make one sooner or later.. like a whole unit, or just a gear set to install inside the stock housing?

 

lol thats ture.

 

i have taking a manual tranny apart a few times and its not that difficult if you know what you are doing but you cannot just swap out 4 and 5 gear. every gear in the tranny is linked together so you would have to find a output shaft with a different gear ratio to fit up with your input and intermediate shaft. as for bolting up a tranny from a different car, good luck. im not trying it thats for sure.

 

To hell with all of this I'm getting a K20 6 speed! Anyone wanna see a tc that can rev to 9 grand!!!
