    Fast Intake 92mm v 78mm

    Alright I paid a guy $600 cash for a Fast Intake that he claimed was a 92mm but once I received it the thing was a 78mm. So should I get my money back or keep it and try and recoupe some of it and if so how much?

    78mm IMO is totally not worth it. Return that thing and buy a LS6 or a used FAST.

    So a regular ls6 manifold is better than this one?
    I was thinking that I would ask for two hundred back?

    You have a good point there. I was more leaning towards get your money back and buy an LS6. Fast 78 just makes no sense to me. If your going to pay for the over priced and poor "revisions" of the FAST... 90/92 only way to go. IMO.

    If I am going to have to shell out say around 300 for the LS6 and shipping I would rather make sure it is the better of the two since I am going to be installing a vortech supercharger on later this year. I already have the charger just need to buy the fuel pump and injectors.
