912 Is turbo

The Rockwell-Collins ECU running your 912iS will have no idea what to do with boost, and there's no way to reprogram it to fuel the engine properly under boost or to handle wastegate control.  If you want a turbocharged engine, the simplest way to do it is to buy a 914UL or contact Edge Performance*.

*Are the words "Edge Performance" considered blasphemy here?

The only way to add a turbo to the 912iS is to contact Thomas from Edge Performance and see about the options they may have available. Below is the link to their website.
