Currently shopping around for a turbo that can eventually make me 250hp on a na8,just saw a "S15 T28 turbo excellent condition, inlet snout, actuator oil line 14411-75F00 $350 ono" for sale, and i was just wondering would i have fitment issues with this on a mx5, also does anyone know much about them? i know there non ball bearing turbos, and I'm sure there more reliable than a churbo anyway, really keen on buying one just not sure if I'm making the right choice in purchasing it, IF not what other types of turbos are suitable for my mx5?

Well depends on which options a bit better on costs, right now I'm know a fabricater in Australia that can make me a manifold and dump pipe and other things, but if you know of some premade reliable manifolds or down pipes that can fit on a t28 turbo I'd appreciate some advice.

Flyin miata will definitely sell you just the manifold. That link I posted allows you to build a kit with as much or as little a kit as you need. As a bonus, you will receive all the pieces at the same time.
T25/ 28 turbos share the same flange.

Hey nitrodann yes that was me, currently just looking at all options with the setup, that's fair enough, I will let you know when I'm ready for the go ahead, I've purchased a apparently blown seal turbo t28 off a Silvia, more pictures and info will be put up on it tomorrow, apparently the previous owner put way too much boost through it over 20psi and his oil pressure dropped and apparently it started leaking, I might need to find ways of testing it or rebuild myself as I'm trying to keep costs to a minimum

OP actually came to me first to see if I would ship one of my setups down to Australia. While I have not looked up shipping costs yet I told him it would most likely be extremely costly and that he should probably goto you instead. Glad to hear from you that shipping in stuff is cost prohibitive, I figured you would go the Begi/FM route if it made sense.

Well this is the turbo i bought a t28, rebuild kit off ebay from this link
Garrett T28 Turbo Rebuild KIT SR20DET S14 200sx Gtir T2 | eBay
planning to rip it apart clean and change all the parts to begin with to make sure it will run, as I have no idea what happened when it was "blown".
I've noticed with the waste gate flapper, if i get my fingers around the smaller circle area and move it around the flapper actually moves left to right and around, just wondering if this is normal or needs fixing?

The compressor side, one of the fins look a bit manky but planning on giving it a good clean and hoping it works ok

Not sure what those brackets are around the compressor side could it be that these come with a heat shield and my particular turbo hasn't got one?
Needs a good clean, I think it needs new studs on the intake side and the threads look a little damaged and a flange as it didn't come with one, I think ebay will do the trick, need an oil drain fitting plus many other things, for the time being looking at taking it apart with heaps of guides and videos online for the time being.
