    Default NA plenum on supercharged motor

    hey i just recently bought a supercharged motor and Im about to start upgrading it. now i was thinking of this idea.

    i was wanting to get rid of the supercharger and instead place a turbo kit instead which would produce the high boost that I would get from a supercharger but get a better and higher power curve. i was wondering would the NA plenum fit onto a supercharged motor? and then redo all fuel rails ect?
    wanted the lower compression and i love the sound of a turbo.

    is this a good idea or stick to the eaton m90 and do that up and maby upgrade to a wippel unit for quicker boost.

    The Ecotec intake manifold will fit right onto the L67 heads. The 1 and only difference between the L67 and ecotec heads is the injector location. I would tap and bung the injector ports on the ecotec intake and run YT fuel rails or even make up some custom jobbies to get around the intake runners.

    Turbo for the win IMO and that's coming from an M90 L67 owner
