As per title, anybody advise? Just need to know if they'll bolt up to the heads with no mods needed. Had a quick search but couldn't find a definitive answer.

Thanks fellas.

They will fit. However I'm not sure about the sump on the 2.5 though.

 

Thanks Shaun, the sump is the twin scroll type so no issues there. Just didn't know if the distance between the ports on the left and right heads (i.e. from one side of the engine to the other) was the same on 2.0 ltr and 2.5 ltr.

So will any year twin scroll headers fit or is it only from say V8 onward?

 

Yeah... I thought that was the case about the 2.5 sump, but didn't want to say something I was not sure true.

Impreza only had twinscroll from MY03 (v8) onwards so that's fairly irrelevant.

 

Thanks again Shaun, exactly the info I needed.

Just need to find some now pref with up-pipe, anybody?

 

I have a twinscroll up-pipe that is in my garage.... not sure what its worth though.

 

May well come back to you about that Shaun depending on what results I get from my wanted ad.

Cheers, Neil
