twilsonx Posted April 24, 2008 Share Posted April 24, 2008 I currently have an N47 but I'm building a P90 to swap. Will the MSA 6-1 header I already have work on the P90? I know the N47 has oval exhaust liners and the P90 has square, so I don't think it'll work. Travis Quote Link to comment Share on other sites More sharing options...
nbesheer Posted April 24, 2008 Share Posted April 24, 2008 Yeah people have run square port exhaust on round port heads. Quote Link to comment Share on other sites More sharing options...
twilsonx Posted April 25, 2008 Author Share Posted April 25, 2008 It would be the other way around, round header on square exhaust ports. Quote Link to comment Share on other sites More sharing options...
BSD Posted April 25, 2008 Share Posted April 25, 2008 Last time I checked you couldn't do that, just square port heads on round port headers. Quote Link to comment Share on other sites More sharing options...
nbesheer Posted April 25, 2008 Share Posted April 25, 2008 Oh, I stand corrected. My bad. Although round port headers on square port heads would cause restrictions EDIT: I just corrected my self http://forums.hybridz.org/showthread.php?t=123377&highlight=square Square port headers on round port heads WORK Quote Link to comment Share on other sites More sharing options...
