Helping a friend instal a kit on his NX. We have the manifold taken off and we want to inject the nitrous into the manifold via tapped runners. I need to know the best angle to drill and tap the manifold. I heard shoot for the bottom of the manifold, and from some friends with V8's they say shoot at the top. I think it would be best to shoot in the middle. I figured you guys know your shit and before I set the mill up to drill and tap I wanted to get some responses.
Thanks,
Tim
