    408 intake

    OK guys, most know about my 408 setup. I have an LS2 90mm ported TB in the works, now I need intake info.

    I don't want to drop almost a grand on a FAST unit, so I am thinking LS6 intake. I think either a stock one or a ported one? LS6 is a 90mm unit right? I have read the thread on the swap, but have a question...I already have 60lb injectors which required the pigtail swap. So I don't have to do that again, right?

    Thanks in advance for your help.

    Sounds like they have it covered.

    LS1 intake - 78mm
    LS6 intake - 78mm
    LS2 intake - 90mm

    Word has it that FAST is developing a 94 or something like that intake for the LS3/L92/L76 world

    Your setup is already Built,proven installed and running !... and you know your truck Runs Great down bottom and drives nice you just need more power up top.. My truck pulled twice as hard up top with a Single turbo As what the Bottom end Pull from the supercharger was ... I vote you Buy turbo Parts !!

    Sorry I did Hijack your post .... But you can have the best of bolth worlds ... I am not sure if the ls6/ls2 will lose any low end at all but .... Then you have to mess with fuel lines,sensors, making the huge 200 wireharness look decent since its not fasten down to the truck intake...

    Does the LS2 in the TBSS use a truck type 90mm intake? I haven't had the pleasure to poke my nose under the hood of one in the daylight.
