hi can any1 tell me whats the difference between the 1.8t engine codes mines is AGU I think.
am looking for new engine as she done 176,000 now and theres one ave spotted only done 86,000
but has different engine code from mines

Agu has big valces in the head
But only a small turbo.
In my oppinion its the best engine to have. 176k isnt overly bad if its been looked after.

Mileage on these engines mean nothing it's the way it's been looked after

The agu is a bit of a nightmare when it comes to mapping the car very few people can do it right

Agu with a ko4 works well but as mention not many people can map them. Early agu is only chipable and to ko4 upgrade a custom chip has to be wrote.
As its classed as old technology now even less people can do it.

A ko3s will bolt straight on and is less work. Best bet os to ring tuners before hand and see who can actually do it.
