Changing individual gear ratios?

Taller is that the ring gear side by side the XD is taller than the Yaris ring gear

Oh, yes, I noticed that too. If you just put the diff and pinion shaft in, they will scrape against each other. If you install the center housing and put the retaining clip on the bearing, it lifts the pinion shaft up a few mm, which should give plenty of clearance.

So going for track use... Swapping XD final drive out of the first Gen would be the way too go?

I was looking in to parts for my XD tranny 2 & 3rd syncros, and notice the the 3rd gear is the same for most toyotas with C5X, 2nd gear is for the XD and 09+ corollas and the 1st gear is unique to the XD. What can be the difference in them?

I'm not sure I understand what you're asking for. The difference in gear ratios, the difference between part numbers for identical rations, or something else?

With the xD FD not really being an option due to bearing/shaft size, and I want to use my OS Giken LSD, I wonder if the 3.9 FD from the C150 in the Paseo would be a better option? I think that might only be a 6 bolt. How about the 4.0 from a C52?

I would stay away from the C15x series, since they're 6-bolt. Unfortunately, my research hasn't turned up anything in the C5x series with a ratio other than those on the Yaris and xB, but I've also never torn down a C52.

The output/pinion shaft bearing has the same OD, it's just a different ID. Easy to swap with a blind bearing puller. As far as overall dimensions go, the Matrix and Celica differentials seemed to fit just fine--the axial length between the taper bearings looks to be identical.

Have you evaluated any of the S series boxes, like the S53 from the Celica?

Jason you might want to look for the TRD 41201-NP100 final drive.
I believe the older AW11 MR2 and Celicas with the 4A-Fe engines used that final drive(4.058). Its a C52 so I'd imagine it would work.

The TRD set has been listed as discontinued for years... Certainly its possible there is one out there, but good luck tracking it down.

hello ,sorry to bother you guys but i have been successful in using the c60 celica gears in my yaris c50 ,i could only use gears three , four and five ,the shaft of the c 60 is the same as the c50 except it is a little longer (for sixth gear ) , i also used a 4.31 off a first gen xb. I have also swaped internals out of a 09 corolla c59 into a xd case to get 4.31 final and a closer 1st and 2nd gear. i didn't want to cut the frame to get a c60.

[xnamerxx]

Do the gears just press on or is there more work involved using the C60 3-4-5 gears?

[froger]

they just press in but i think you had to use the yaris synchros and sliding sleaves not the c60 celica ones
