    Does anyone have any vacuum line diagrams for a singe turbo rb26 (whole engine side)

    Does anyone have any vacuum line diagrams for a singe turbo rb26 (whole engine side)



    I have a RB26 in my Z with a T 8834D External wastegate with a blow off valve. I'm looking to see if anybody has a vacuum line diagram for a single turbo set up. ((This means under the hood all vacuum lines single turbo))The
    previous owner of the engine had a bunch of vacuum t's. If someone can point me in the right direction that will help thank you.

    What is confusing you exactly? The wastegate has an instruction manual directions to follow, where external gates always use pre-intake manifold pressure from the intercooler plumbing.

    bypass valves always get intake manifold vacuum.

    fuel regulator is intake manifold vacuum.

    Anything else missing?

    single turbo isn't an OEM thing for RB26 engines so there is no OEM diagram. You customize it to be clean and work properly, and not melt/crack.
