Hello I have a SC430 with 268,00 kms, I am intending to swap the motor with one of a Soarer 2002 with 85,000 kms.

I found the engine levels, in the SC430 it says 3UZ-Z88 and in the soarer it says 3UZ-Z22 other than that the engines and transmissions look very similar. Does anyone know that is the meaning of the suffix?

Thank you,

 

It probably refers to the region of the world. Asia, Europe or Americas.
or the years. 2002-2005 and 2006-2010.
my 2002 looks a little different than my 2007.
the vacuum ports are in different locations on the intake.

 

May I ask, what is the reason for the swap other than the millage diff? the original engine is 268k km (about 167k miles) so it's not so bad considering these engines last 2-3 times longer if properly care for.

 

Thank you everyone for replying to my thread.

The only reason is the mileage I have concerns about the transmission. I don't have any apparent problems yet but I got the drive-train available. I
