Just heard back from Luke @SubaruBoy
He says there will be no problem at all with that setup.

Thanks mate.Good on you for organising this diby... I'll be hanging onto my 80 for a long time too.
Been watching this from the sidelines- in simple terms it seems to me like the MMP turbo is about $500 cheaper than a Gturbo Bad Boy, but will probably not last as long. Seeing as this is a brand new turbo for these motors, even if the performance were better than the much sold Gturbo, it's just not that much cheaper for the risk.
I'd be interested if it were say half the cost (or less) of a Gturbo at this stage.
I've rushed in and bought various items for my 4x4 vehicles (no turbo though) over the years based on initial hype and been let down almost every time, sometimes with the vendor closing down. Just glad I never almost bought a Xxi W2A intercooler!
I really hope the MMP turbos are great for those who get them, more choice is better for us all. I just won't be putting one of these on my truck yet.
Having a unit that has a dyno attached to it and is plug and play is no small thing. I certainly understand that. The BW turbine failure is a bad deal even if the guys did overspeed it. I mean how common is it that you see 100$ Chinese turbines structurally fail. Cheap turbos fail, don't get me wrong, bad bearings and such, but to have all the blades separate off of the turbine shaft is not a normal deal.
I see you are in Australia so I can understand your point. Earlier I posted a price breakdown of what I was quoted with shipping to the USA for a GTurbo and I believe that makes a large difference for me. Without that it would make the decision harder for me. It will cost $280 AUD to ship plus a $300 core that's not worth shipping back and leaves me with my stock turbo as a spare. That makes the Gturbo $800 AUD more expensive on this side of the pond.
Wow. Thank you for that insight Luke. That is very valuable information. Extremely hard to find information like that. Seriously. So that is cool that you've dissected several dead BW turbos. The fact that you've done more than one is enough to confirm my ill feelings towards their gamma delta pie in the sky turbines. 95k rpm is cruising on the freeway part load. Hardly much stress. So your suspecting the plastic cage might just be a contributing factor to the turbine failure? Bad ceramic compounds? Perhaps the cage collapses and then the turbine or vice versa? Any way you slice it I'm fine with old school heavy turbines that do take perhaps a full 1/2 second extra to spool compared to one as light as a compressor. Do you think the plastic cage deteriorates from hot shutdown as well or is it just an unsuitable material for the crucible? A turbo center section has to be one of the most awful places in your engine next to your combustion chamber. To be honest the thought of putting a piece of plastic in such a critical area in such a demanding environment does seem like it was perhaps a bad decision. Be interesting to see engine bearings and cylinder walls after they have been subject to ceramic bearing particles too. Very interesting.....
Food for thought for the fence sitters in the mmp group buy. Nothing against gturbo only using them as an example . Gturbo started as a guy at home doing his thing for people on here . mmp isn't new to turbos only to mud
