alright i suck at the endless searching. I basically have a donor car thats a s5 TII. Now the way i thought it would be is removed engine, harness, ecm, fuel pump and installed in s5 vert. however the more i read the more i am getting mixed signals on this.
Most about the wiring harness since that really the only difference (i think) i have the wiring harness and i planned to just use it but will i need to do any mods on it? I have the option of using either the na ps pump or turbo but one of them is going on my drift car so.....

I am heavily mechanically(lead vw tech) inclined i just seriously can't find a straight answer and my rotary adventure is just starting mechanically so help would be awesome

 

I pretty much asked the same question here and got an answer.....

well the main question is "is my remove and straight up install into vert the whole story?"

but i do get your point that the ecu is going to work fine
