Well, reporting back now that I have the 4828 installed.
This is just butt dyno results on something that is extremely conservatively and safely tuned (Read: Basically completely untuned, on basemap), but even as is it reminds me a LOT of my old SR20 T25 turbo, as opposed to my ch..ch..churbo.
Boost is close to being an on/off switch like it was with the old SR20 T25.
So far, I'm -extremely- happy with it. I can't wait to get this thing tuned, spool is damn near instant.

Getting pic updates to build thread in today guys. And trying to figure out my short, but that's another topic.
I'll probably be getting and posting spool data with logs tomorrow, assuming that classes don't CONSUME MY SOUL.
(Edit) The CXRacing 2560 analogue. Don't ever get it. It's crap.

I went back and found my measurements I took. it's 64mm, where a regular t3 is about 4-5mm smaller.
My funky Chinacharger has a crazy inducer on the turbine, but the same exact profile/diameter exducer compared to a real t3 wheel.

Update for you guys....
Something isn't quite right with the turbo setup. I can't figure out what it is easily, I first thought it was a busted coupler or something, then maybe there's an exhaust leak@the turbine housing, I just don't know. There's an issue building boost and holding boost that I'll worry about this weekend.
But even in the current state, untuned, in 4th gear, I was able to enter boost before 2krpm.
Even in the current "Not Really Working and needs a **** ton of work done on it" state, I can definitely see why that local tuner made such a big deal about this turbo.

Soz bro, the last couple weeks of my program are way heavier than I anticipated.
I did **** all last weekend, only did work on final projects. Same for this weekend. Same for next. Same for every day involved until final's week it appears.
I'll definitely get them ASAP I promise, but I have no ETA now. I have to fix the boost issues which aren't an immediate or easy fix.

My worry is horsepower - I'll have to dyno it asap. The 4828 is good for up to ~400 rwhp, although unknown as to what the max is on a BP engine.
