1.8t aeb and 1.8t atw what diffrence mounting? wiring? parts? dont car to much about internals or specs just what to know if both will work in the same car or what i have to change to make an aeb work in a atw car

 

AEB has 20 mm wrist pins for the pistons, ATW has 19mm.
ATW has secondary air injection, AEB doesn't.
ATW is throttle by wire where AEB is a standard throttle cable.

To swap an AEB into an ATW car you need-
AEB motor, the bottom end is the same with the exception of the wrist pin size
AEB wiring harness
AEB ECU
ndbw gas pedal
throttle cable
plus a few other things.

The motor mounts are the same. There may be a diference in the water pump also.

 

So couldnt I just change the throttle body and add the the bracket for the air injection pump

 

I am sure that some of the sensors are diffrent but I should be able to switch housings and what not to make ot match to the current wiring.
