Clutch Interchangeability

[ITA]

I just picked up a 2007 Yaris. I noticed that there is some clutch slip (no tach, but I can tell if I get on it, I am not accelerating as much as I should). So, I am looking into replacing the clutch with an Exedy OEM Kit. thebarber stated in this thread (http://www.yarisworld.com/forums/showthread.php?t=25597), that we can use clutch kits suited for the 1zz and 2zz. They are a bit cheaper than 1nz kits. Can anyone confirm that this is true? Thanks!

Here are examples for reference:

Yaris Exedy OEM Clutch (https://www.ebay.com/itm/Exedy-OE-Upgrade-HD-Clutch-Kit-for-2006-2012-Toyota-Yaris-1-5L-4cyl-1NZFE/132707821494?fits=Make%3AToyota%7CModel%3AYaris&epid=110152977&hash=item1ee600a7b6:g:q8YAAOSwL9pagCA3)

Celica GTS Exedy OEM Clutch (https://www.ebay.com/itm/EXEDY-UPGRADE-CLUTCH-KIT-FOR-2000-2005-TOYOTA-CELICA-GT-GTS-1ZZFE-2ZZGE-1-8L/132724333188?fits=Model%3ACelica%7CSubmodel%3AGTS&epid=1238729878&hash=item1ee6fc9a84:g:Z7EAAOSwigxajh8p)

According to these two ads, the outer diameter and input shaft spline for each application are identical, yet the Celica application is $50 less.

If you scroll down on those ads, it even list the clutch disc and cover part numbers as the same. I wonder if the Throw out and pilot bearing are the same

Subscribed. Apparently the 1nz clutch fits with the 2zr meaning a 1zz and 2zz clutch would also work. Gives plenty of options

Blue Vitz has a 2zz clutch in his echo

I have a OEM Celica GTS 2ZZ clutch in my echo as well.......works great.
