in addition to us all being aware of it starting from over 10 years ago, it’s pretty much just bits and pieces of pulverized dead horse from all the beating

My plan is still to follow a lot of what @Brettus has done with his build. It looks nicely streetable, which is mostly what I care about.

Look at this exhaust manifold Brettus, seems like you are inspiring people...

at one point was wondering if you were in direct collaboration with him because he seems to walk step in step with you on recent things, but am confident that wouldn’t be your choice in turbo, which he claims there will be good to 8500, lol. Seems like he must be lurking about but he’s had a bunch of similar BHR type products with his own brand name on them too.
I suppose when you’re dependent on just copying other peoples ideas you’re also prone to making mistakes lacking understanding, the same understanding needed to develop your own sound ideas.

Xona turbos with model numbers ending in "S" means it uses the "UHF" splitter-blade turbine design. The lack of the "S" at the end means it uses the older traditional turbines, which aren't even listed on Xona's website anymore as they're being phased out. And their choice of using the XR5448 is definitely on the small side, imo. Also, the fact that they're using a TiAl 0.8 A/R housing means it's the IWG model (as can be seen in the pics). The EWG V-Band housings are either 0.63, 0.82, or 1.03 A/R. Btw, does anyone know the price of their kit? I don't see it listed...
Edit: I'm also surprised they didn't use the opportunity to utilize a X2CF90 compressor housing since they're doing a low-mount setup. It's basically a X2C compressor housing that has a (fairly gradual) 90° bend that would point the compressor outlet towards the front of the car. It's technically designed for a GT-R, but I don't see why it couldn't be used for other applications. I think it would be nice to have since some members have had leaks/issues with silicone tubes on that 1st 90° bend. It'd 1 less point of failure to worry about.

Well ... the Greddy uses a 55/65 turbine with a 0.73ish AR and that's a 48/? in a 0.82 ...So if it's old tech. it's not gunna be any better than the Greddy. Really bad choice IMO. I's not like there aren't way better choices in the xona range either.

The turbine on the XR5448 has a 48mm exducer & 54mm inducer while the compressor has a 71mm exducer & 51.5mm inducer. If they went w/ an "S" model turbo of the same size, it would be the XR5451S, which uses the same 54lbs/min HTZ compressor wheel but with a 51/57mm turbine that features their "UHF" splitter-blade design. It would certainly be an upgrade compared to the XR5448 but still too small for a 2 rotor, imo. The smallest Xona turbo I would consider putting on a Renesis would probably be the XR5757S but my personal preference is actually the XR6564S. I guess their top priority must be spool/response, but a turbo that small is simply choking the engine. I'm having a really hard time trying to understand their thought process when designing their kit...
Btw B, do you think it's a good idea to use an IWG housing?

He has produced a very shiny manifold, see here. Please keep any comments constructive.

I may disagree with B on some technical aspects of his manifold, but with the EWG it’s clearly a significantly better design than what was done there on that one point alone. Shiny or not, IMO that won’t be anywhere near optimum for IWG and will be further compromised by the undersized turbo being proposed. Again, seems to be overlooking the obvious.

well yeah, both our positions are IMO which is a good reason not to get wigged out over a difference of opinion
we’ll find out at some point if Garrett ever comes through with the T4 0.92 AR housing. With copycat artists like that guy around I’m keeping it under wraps for now. The one thing I’m willing to reveal is it will be fabricated in mostly T347 material. It might even be “shiny” if I’m feeling kind sparky about it at the time
not sure if you saw this;
