6 speed swap project

Hey guys, I didn't want this info to get lost at the end of my 2zr swap thread so I started a new one. I'm using a C60 close ratio 6 speed transmission from a 2003 Toyota Celica GTS.

Check out the first writeup here:

When I swapped my C160 into my car it was a bell housing swap and frame notch to get it to fit. The C60 is virtually identical, except there are a couple different versions. Mostly just forward mount or rear mount shift cables. The C60 also uses larger axles splines vs the C160 which is why I went with the C160. I was able to retain the stock axles.

Good luck with the swap. You'll really enjoy the ultra short gearing for track duty.

This absolutely warrants it's own thread. The short vid ending with your smug mug got a chuckle out of me, too lol.

Interesting.

Do you have any idea what axles I'll need for the C60 differential? I'm thinking of trying a set of xD axles first, unless there is a reference somewhere for spline specs?

I have a first gen, so your application might be different.

Are you using stock yaris axles now with stock hubs?

Just read your blog...

You might just need to swap the diff from the 5 speed and you'll be all set as the axles fit it already. C60 uses an 8 bolt diff, so if the C50 has the same thing, all you should need to do is change the ring gear.

In my Echo, i was able to use the stock axle in a C59 5speed bolted to my 1zz, every where i read the conversion 5 to 6 speed c60 would not need new axles on a corolla or vibe based car.So i would be able to fit the stock axles in the c60 in Theorie. You guys agree?

Theres a guy here in quebec, used the 2zz axles in a yaris hub and stock 5speed trans. Are the axles from vibe,celica, and matrix all the same?

Sadly, there are two different sized 8-bolt differentials. I learned that the hard way when I bought the wrong Quaife LSD and had to pay a 25% restock fee. The larger displacement engines use an 8-bolt diff with a different diameter shoulder for the final drive ring gear and a different spline count in the spider gears. It might be possible to swap spider gears (I could check using the spare diffs from my gearbox teardown) but it's easier to just find an OEM axle that works.

From what I can see online, the spline counts from the xD are correct. Not sure about diameter and length of the insert stub, or if it's the same diameter, but I'd be willing to bet that they will work.

Awesome Sam, thank you. I'm assuming at this point all of the sub-compact Toyotas use a 23 spline axle, and the regular duty cars like the corolla, use the 20 spline. It looks like the Scion xD has once again become a very important part of the Yaris swap project

4.5 fd sounds nice. My only gripe about the c60 is the shifter feeling sucks.

Thats odd, since the C60 and C50 have the same shift mechanism inside the trans. It must be something related to the C60 not having counter weights on the end of the shift rod, where the C50 does.

dude

thanks for documenting all this.

....you say that you got the tranny from a junkyard, did you price them out brandnew first? / I'd be curious to know if Toyota transmissions are cheap like Honda transmissions? (ie: you can get a brandnew B-Series transmission for like $1800)

I looked online briefly and saw the used C60's going for $700-1000, they are still a rare and coveted item I guess. Honestly when you start a project like this not knowing how difficult it can become or total project cost...I wanted to start cheap, figure it out, then others can learn from our progress and do it better on their own cars in the future.


ALSO

Blog is updated with Part 2! Getting closer my dudes!
