    Recently i blew the bearings in passenger side GT2860 running 25psi
    I was hoping to get to 30psi but the twin gt2860 setup started losing boost anywhere higher than 25
    Question 1- Do our engine bays allow for twin GTX2967 setup?
    Bit of a 2nd question here as well- should i delete the oil restrictions on 2nd attempt?
    I still don't know the cause of the bearing failure so any thoughts are welcome
    New motor, forged, big cams, headwork etc- everything was new except the turbos
    Are we supposed to do anything with the vg motor to stop bearing failure?

    I remember a few people running 3071's a while ago, so the 2967 should fit.

    People in the US are using them, can't assume they will just bolt on, but they fit.

    The housing seals will probably leak if you remove the restrictors, imagine how pissed you'd be if they leaked after everything was up and running.

    I have a pair of GTX 2863R 0.64 A/R for sale if interested. Never used with ceramic coating of exhaust housing plus Forge actuators. Purchased from GCG Turbochargers - not Chinese copies.
    No longer required. Selling $4,000. (fixed price - no offers) with collection or postage paid by buyer. PM me if interested

    The gtx2967 (if genuine housings) will not fit without modification. The us guys using them (not sure I can think of any off top of head though) have ash or msp/custom manifolds.

    The gtx2863 listed above- will flow 36psi if you can keep the gates closed and generate over 500rwkw worth.

    Thanks ProckyZ89

    For those that are following this thread, I found a Turbo place in Molendainar (Gold Coast) that machines turbos to custom specs. I think they call this high flow.
    There is 2 cold side housings available in the 2860's
    Apparently i have the larger ones...winning
    They are going to machine out my turbos and make them into a GTX2971 so i have no fitment issues (Current setup is with AMS manifolds with bellmouth dumps)
    We worked through the maps and ended up with 2 choices- GTX2963 (if i wanted to run them hard) or GTX2971 (if i wanted longer life out of them)

    Looking forward to testing the maths
    It looks like about 4300rpm for full boost at 40psi to 7,000rpm
