    Default Jet86 - Australia's first twin charged 86

    Jet86 was built as one of Australias first Turbocharged toyota 86's, by Kalen Gray, an experienced "automotive genius" with multiple fabrication degrees and automotive know how.



    Not being enough with a Turbo, Kalen decided to trump a few other major players modifying the Toyota 86 / Subaru BRZ in having the countries first twin charged Toyota 86.



    There have been some interesting comments on the NSW BRZ facebook page , from fellow ethusiasts.

    One that particularly comes to mind is #mrtcaneatateinchargeddick

    This is one epic build, and will continue to grow bigger , better and meaner.

    Full build thread here...

    sounds like shit.

    dont like all this twincharging bullshit. so complicated. would be cheaper and easier going a larger displacement engine and modifying that

    I agree guys, if twin charging was worth the effort there would be a heap more kits out there for other makes and models

    I like this for a couple of reasons though, mostly because of the hks twin charge kits that that were available for the 4a

    Twin charging is worth the effort, if the reason for it is understood.

    A lot has changed in recent years, and its not all about by-pass valves and complex switching of systems. A lot of manufacturers are looking toward it now-a-days, and that is because it can be made to be far more efficient than conventional systems.

    Yes, similar results can be achieved with variable vane turbos, but, they are also very complex in design, making repairs ridiculously expensive, and very very hard to "tune" to an application.

    Understanding boost multiplication, and boost control, is the hardest part, and it doesn't take a scientist to do math if you have some patience and understanding.

    My comments were mostly about the amount you need to spend to setup a twin charge setup correctly. Sure you can control the boost and have the sc for low down and the turbo for up high in the rev range, but IMO if you pick the right sized turbo it'd still be an absolute blast to drive.

    How would you recommend setting up the supercharger and turbo adn what sizes?

    I may of got it wrong, math skills do need work, but in a compound configuration, a turbo with a flow rate of 0.55kg/s, with a 1.0 rear housing @ 10psi, blowing into a charger that can deliver between 0.30-0.40kg/s of flow @ 8psi would work well on a 2l engine with final boost pressure of 25psi or so.

    I do think im wrong though.

    But basically that would work out to a garrett 35/40 blowing into a rotrex c30/94, I think that would work.
