The turbo details:

GT2871 compressor wheel
New GT28 non ball bearing CHRA
360 degree thrust assembly
upgraded wastegate actuator assembly
balanced to or under .5 gram/in2
upgraded compressor housing with custom outlet for the factory intercooler piping/couplers

They used to recycle a K04 and port the hot side, but they were prone to cracking from insufficient material and heat cycling. BNR just had their own castings made, so now it's a non-issue and the reason I'm pulling the trigger. It's a perfect match for our direct injection fueling limits and 25% E85.

One of the best Speed tuners made 417/395 with this turbo with meth injection (and later 445/412 on the GTX2867r with rods/pistons/port work), but I don't intend to push it beyond 370whp. That's a decent safe zone if you reverse taper the boost to keep the rods in the block, and the OEM clutch and trans can handle it nicely. This is still my DD.

Just recently we've had some MZR's break 700awhp (speed6) and 800whp with several similar builds taking place this winter, so expect to see some low 10s passes from the Mazda camp this year, maybe tickle the 9s.
Great info! Cool option by BNR, it's a nice option for you guys. That's great that they do that. And I'm actually a bit surprised that the Mazda internals aren't somewhat beefier to handle that type of power increase. And I don't mean that negatively by any means.

Still a great daily driver! I daily mine as well. Always puts a smile on your face haha. Think you can get some of the MZR guys on here to post a build? It would be cool to expand and see other builds!
