    right, I have the garrett gt2554r on its way and thinking of pairing it with the garrett gt2871r .86 but worried it wont make the 550 power I want.
    so whats your thoughts on gtx3072?
    i also went to pods last weekend and it just makes me want to build a mental track car!
    any ideas on size of wastegate from gt2554r? I was thinking trial 44mm

    Hi There, Newbie here and wondering if you managed to modify the Jabba underslung to fit an external gate. Some info would be appreciated :)

    Not with out welding an outlet on... the design of the collector doesn't lend itself to work well with an external gate and tbh you will gain very little doing it on this mani... you would still end up with a **** manifold either way... when it cracks (as it will) you would only have to do it all again...

    Hi there,
    Thanks for reply:)
    My problem is the forge/Owens actuator physically unscrewing the treads and coming loose so I'm considering external. Reliability is the main issue here.
