Differences between 2.0 TDI 143 and 170?

[phatAvant]

Does anyone know what the exact differences between these 2 engines are?

Different engine management? Turbo? other parts?

Just found some threads that indicate that it might have a bigger turbo, different map, and injectors, can anyone confirm this?

its definitely something along those lines otherwise superchips would be able to map a 143 to the same as they can map a 170.

Would love to know to exactly what it is, to see whats possible.

There is not much difference in hardware between the 140 and 170.
According to ETKA, the CR-170 has different part numbers for the following.

Turbo
2 different intercooler boost pipes
Flywheel
DPF
EGR cooler gasket

Not sure if the same applies to the older PD unit.

Can't remember if the 170 has larger front brakes, will check later this evening.

Thanks for that, assume the brakes will be the same as it does a good job of stopping (atleast my 143 does).
