    Basically do this;

    -unbolt stock intake
    -unbolt itb's from 20v intake manifold
    -bolt T3 adapter to head
    -bolt itb's onto adapter upside down
    -bolt on your choice of velocity stacks

    Things to note;

    -use 20v TPS
    -the T3 vacuum bungs are in a stupid spot
    -use the T3 vacuum ports for vacum, not the throttle body ones
    -T3 adapter will need slight modofication if you have a FWD water outlet on your engine
    -I suggest cleaning up the inside of the T3 adapter (smooth out the edges at least)
    -use 16v injectors and fuel rail
    -there will be no form of idle control except for opening the butterflies, or opening a vacuum line
    -you might want a vacuum box to connect all the throttles to, then connect that to brake master, fpr etc.


    thats a basic rundown, obviously not including ecu, wiring so on.

    Im sure there was a much more thorough guide somewhere on here or on twincam.org too...
