I Have been interested in this type of project for some time . I wanted to put an RS3 motor in to the Electric ABT Van T6.1 , Space restraints holding me back at the moment , but still keen to have a go .
I have lowered an ABT E Van and had a good look at it , All the original harness is still there ( unplugged and strapped safely out the way .) this would be easy to convert back to what ever spec the van started life as ( diesel motor ) they have a DSG gearbox so i am unsure if this could be used and the ratios are still as per a diesel van , big help if it is . I am led to believe the battery is similar to an ID 3 4 or 5 range ?? potential there to sell on . The instrument cluster must be changed but i think the plugs are direct fit .
There is a Facebook Guy JG who has already put the RS3 engine in a T5 , i am sure he was challenged with it , but its running now i think ?
( John if you are on this forum let us know how its going please )
