Alright what is the difference between the wiring harness in my N/A
to my Turbo. I plan doing a conversion and I need to know whats all missing on the N/A harness that the turbo will need.And does anyone have a stock intercooler they would like to sell or maybe a S4 t2 wiring harness.

The NA ECU harness can be modified to work on a turbo engine with very little work, especially if you're not worried about emissions. You will still need a turbo airflow meter, boost sensor, and ECU though.

Get a shop manual and sit down with the ECU diagrams - it's all relatively straight forward. You may have to lengthen and shorten some wires, but it shouldn't be too bad. The pinouts on nearly every input/output to the ECU are in the same position, which makes it a LOT easier.

If you need a stock intercooler, I might have one - I'll have to dig around the garage.
