Sorry for posting the same topic in two different forums but I'm planning to upgrade my 50 shot to a 75 shot on my ss prelude. What do I need? I've read that I need...ignition, spark plug wires, fuel pressure regulator, retarded ignition...I already have colder plugs. Is this all that I need or more than enough? I don't wanna say that I just want the bare essentials but I don't wanna spend too much money to upgrade. I guess I wanna get everything I need to keep from running lean and feel safe whenever spraying...thanks in advance for any replies
