So as the title states in a bind of what I should do . My car was the recent victim of ingesting water and my insurance is going to cover the damages and replace the engine. Question is I found a 2011 wrx Sti engine on eBay and was curious if that would fit in my 06 Sti without to many problems of if any at all. Also would the my old ECU be an issue aswell since the new engine doesn't come Witt the ecu. Should I just have my engine rebuilt or should I go with a complete motor swap . I'd rather have the swap since all the other accessories will be a lot newer. Aswell as the turbo . I'm just concerned that it won't be an easy swap or if at all possible since the ecu is not coming with the newer engine. Any help would be greatly appreciated . Even if it's a different idea . I also have the choice as to where the engine will be done if that helps any . I assume Subaru will replace the short block . But keep all the accessories . Or I could with a speed shop and have them order this engine I found and go from there . Thanks in advanced !
