so i have a swap i want to get under way. i have a ej257 and ej205 heads. wrx intake and injectors top mount. turbo. header uppipe downpipe. bov. all i need to put it together is the 2.0 tensioner. but what all do i need to make it run. Emsmap says my factory 22 sensors will give me issues when i get the other motor swapped in. im in the process of buying a wrx wiring harness and ecu. what harness do i need? the whole harness? dash and engine bay harness? what other stuff do i need. i want to get it 95% together before i take it to iag. itl be swapped in with the automatic tranny. so tranny issues and swaps are not an issue. just wiring engine management and tuning. i plan on having iag splice the harness. instal the wrx ecu and dyno tune it. motor being allready built. any and all help would be GREATLY appreciated. thanks.
