now then lads,i'm building an impreza from the ground up for a rally car the donor car was a uk turbo, the engine i am putting in is an sti red top from a my98 and using a type ra box n diff.
am i going to need a new wiring loom to run it all,will all the dash and other bits fit ok?? could do with an sti ecu also i presume?

also will a turbo fit on sti motor off a uk spec engine?

 

You probably will need a loom. You may not need an ecu, I presume you'll be getting GEMS or Motec on it? If so they replace the boards.
