Well the professional products typhoon intake is a copy of the Edelbrock performer, with the exception that maybe the intake runners need to be cleaned up a little bit. I'm not sure about their throttle bodies though, you can take a look at the TFS throttle bodies on summit racing, I would think they are good quality, one of the cheaper ones anyhow. I wouldn't go with a bbk tb though, they whistle and some people have said that one of the screws on the tb came off and went into their motor.
