I need to change my engine, I also found a company willing to perform the paperwork for changing to the same engine model.
The car is a Toyota Yaris Luna with semi‑automatic transmission manufactured in december 2007.
My engine model is a
2SZFE. The problem is the car was built for the euro ⅳ emission standard which was set in 2005. It seems to be far easier and cheaper find a good used engine manufactured under the euro
ⅲ standard (that is before 2005) and I don’t want a downgrade (there are road restrictions based on emission standard level).
So what are the differences between a
2SZFE engine manuactured before 2005 and a
2SZFE manufactured after 2004 ?
Is it just the ECU and/or Gearbox ? Or are there core changes like the engine block which would requires buying a higher price used engine manufactured between 2005‒2008 instead of 1999‒2004 ?
