I was wondering about this, and Im only interested in hard facts.
what are the external size diffrence between the 1nz in the xB and the 2ZZ in the celica..
Ive herd a lot of noise about the diffrence between the motors, but i would like to know the facts.

Thanks in advace for your help..

 

I don't know...but Activa had to modify the engine bay of the Vitz in order to fit a 2zz in there... What modifications they had to do, I have no clue...

 

anyone got any info at all?
