    How the twin turbos work. 4 stages! Video inside.


    This is the best explanation I've ever come across. Sometimes it's hard to visualize how our turbo system works, so here you go.
    Not my video.

    Very straightforward explanation! Thank you for posting!

    For the sake of discussion about OEM sequential turbo setups in general, these couple of threads are pretty extensive contrasting the sequential twin systems in MKIV and RX-7 FD (notably both were partly developed with help from Hitachi):

    Thats a good explanation... those twins are always fun to troubleshoot... its the multiple little issues like boost leaks, bad VsVs and molestation that people loose it over....

    here is a pull.

    The vacuum lines suggest it is, but I see a dip in the boost gauge, which would indicate sequential to me.
