Hello,
I came here hoping to find someone with knowledge to answer a query.
I'm looking for information regarding the differences (if any) between the 1NZFE (Engine only) over its production life.
I am looking at building one with internals etc, and I am trying to decide if a later one is the same engine as an earlier one.
My Echo currently has the 1.5L 1NZFE, But I have noticed that later model cars like the Yaris etc use the same 1NZFE engine code.
So my query is, are there are differences?
Can anyone assist here?
Thanks.
