good morning everyone, I am writing from Sicily (Italy), my multivan t3 bluestar 1.6 td jx has a blown engine, unfortunately it cannot be fixed and I cannot find any other identical engines, I would need information regarding an engine change with 1.9 td 1z has anyone of you fitted it? Are there any guidelines or a manual for doing this engine change? could you help me?

Fitting an "AAZ" 1.9 TD will make a direct fir and will last way longer then the "JX".
It is a mechanical controlled engine with a bigger volume, higher torque and better reliability.
Going to a TDI, I would go for an "AFN" instead of the "1Z/AHU".
This is a popular modification but more complicated, since you will go into electrics and electronics.
