    Differance between LS6 and LS2 IM

    Ok, im building a 6.0l iron block and using ported LS6 heads, and was thinking bout using an LS2 intake because they have a 90mm TB bore and flow very well, maybe better than an LS6 intake?

    Can somebody tel me if the LS2 will fit my engine and if so what TB can i use that will bolt up and use a cable instead of the drive by wire setup.

    I have a TPIS ZO6 modified 75x90mm intake and TB in the For sale section that will out flow the LS2 by 20hp. I will let them go for 900$ shipped. Would be perfect for that 6.0 block.



    The LS6/ZO6 intake has proven to be better than the LS2...

    LS2 intake would need new rails and something has to be changed with your stock injectors to fit the LS2 intake.

    Another option would be the 90mm FAST intake and 90mm TB. You may loose some lowend and midrange, but the top end will be fine or a bit better than my TPIS I am trying to sell. I miss the midrange pull however. Makes it more streetable thoughout the powerband.

    PM me if you want to see pics or have ?'s
