S4 turbo engine on 85 GSL-SE
 

Since 13b engine just died Im thinking on installing an S4 turbo engine, everything looks straight forward, but I can not find a thread that explains the wiring. I will post a write up with pics after im done. If anybody could give the address or a thread where this is explained . Thank you in advance.

Check the 1st gen FAQ. Depends on how you want to wire it. If the engine is stock, then just use the S4 ECU and use the wiring diagrams in the Haynes/FSM to simplify the wiring for the 1st gen. If you intend to modify things, then starting with a full standalone from the beginning is the best choice.

I am going to keep it stock for a while. Later on I will do all that, is my commuter car so i need it running as soon as possible. Thank you.

Hope you live close to work and food, or have a bike to ride.
