scott Posted March 13, 2015 Share Posted March 13, 2015 Hi guys. Just received some twin su's and a friend had a manifold laying around as well. One's a E36 and the other is a n41. Which one is better to run or there's no real difference? Quote Link to comment Share on other sites More sharing options...
Howdy Posted March 14, 2015 Share Posted March 14, 2015 Just check the carby size. It looks like they are 2 bolt which might be the small 1.5 inch like 180Bsss. I had a manifold like that once - 6cyl with 1.5" carbs that had only 2 bolts holding them on and small ports to the head, not sure what it was off, maybe an L20. If the holes are 1.75" and the port sizes are the same ,no problems use the one with the least castings. . Quote Link to comment Share on other sites More sharing options...
