I just rebuilt my a4 b8 2.0 tfsi and it's running good. However, I seen a totaled s8 for for sale with good drive train. Its a v10 na. Do you know how difficult a swap would be or if it even fits in the a4? I think the b8 4.2 v8 would fit. if I have the complete car I can change the entire engine harness and ecu, trans and tcm. I'm fairly new to audi, so I'm not sure about the security system. Would I need to swap the ignition switch and comfort control module to match the immo of the s8 ecu? I'm lost when it comes to coding. I could do it with enough research but I don't have the knowledge without a "walk through".
