Hey guys, I知 going through process of swapping to a bigger port manifold (second pic) and have noticed couple of differences. Just want to make sure I知 not going to stuff it ...
First pic circled in red shows a coolant pipe which is not in same spot in second pic. I知 guessing they moved this to the middle of manifold as pictured in green?
Also on second pic (where old coolant fitting was) it痴 got a hole now... I think I read it was too do with a temp sensor I think. Do I need to have anything added there ?
Car for reference is a e21 316 running m10 1.8.
