Thanks for all the info guys. OK, now I'm starting to get somewhere. So, brad, how do you differentiate between top/side feed injectors? Is it the orientation of the injector to the manifold, fuel rail, or something else intirely? I was eyeballing 32lb mustang injectors for either a high CR or a turbo build-up. I am still trying to figure out which option offers the best
hp/$ ratio.
