xB final drive swap - Page 4 - Toyota Yaris Forums

^ What final drive is in your '03 Echo?

I swapped to the xB final and it's a world of difference.

According to vibratesoftware.com's semi-reliable info, it's listed as a 3.526:1 final drive. That's even taller than the 2nd gen's 3.722:1. The bigger issue would be finding a C150-compatible input/output shaft: the C15X gearbox is narrower than the C5X. I think there was an Aussie who did a FD swap in his echo and ran into that issue. I thought it was on yarisfans.com, but that's not a valid site. From what I can tell, you're stuck trying to find a Trueno-era gearbox...

Wow, that's a LOT of work! Congrats!

Thank u man. I really don't believe at 7800rpm I make top end power. Never dynoed. Maybe couple cents before or so. What I know engine pulls 8000rpm where stock plug coils end firing so switching off engine till I shift. I preferred 7800 for safety. Just I wonder if turbo build could be more satisfying. I'm not experienced with turbo so I don't know. I don't know which turbo could be better. I don't know. Sorry for O.T.

Really it is not much work respect to what u done and studied with your multi swap project. Unfortunately here in Italy I cannot find gearboxes u have in US.
So only I could do swap from 1zz kaaz set. But when I rev 1st to 7800rpm and shift to 2nd I'm at 4700rpm too low for my engine torque band. Much better Celica gears 1st-5th where I see with gear calculator revving 1st only 7000rpm and shifting 2nd is beyond 5200rpm. This is right for my engine.
Can I swap C64 gears to my tranny? I know Trd C52/C56 33030-AE001 same ratio as Kaaz Celica 1st-5th. But I don't know if different gear/shaft size.
Maybe u saw => know.
