Stay with the Neukin ram horns. You need to learn how to drive your car before you even touch any nitrous. With the set up you got going on with the Civic, it shouldn't be so laggy that you need nitrous. 10:1 pistons won't lag as much as the 9's. Edelbrock victor x manifolds seem to be best for forced induction applications, so if you're looking for one get that one along with a bigger throttle body.
Like someone said, what do these questions have to do with a boost controller? haha
