Old post, bumping for one reason, to give my 2c on the cxracing turbos:
The CXracing turbos are terrible. Ended up getting my hands on one, it hasn't even reached full boost (14-15psi) by 5000rpm. And yet, it's supposedly between a 2554 and 2560.
My old T25G was way, way better.

I made sure the turbo i got had all the wheel size specs so i knew what I'd be getting my hands on. I confirmed the measurements once i got it.

oh that's crazy. did you measure stuff before you put it in? i know Levnubhin got a turbo once he though was a 2860 size and ended up being like a 2876.

It's ***** awful spool-wise though, I've only reached 10psi by ~4500ish rpm. TERRIBLE turbos. It spools like it's a 30xx turbo, not a 25xx - and yet, it only has the power of a 25xx turbo.

I never installed this. It had a weird downpipe flange. I think a t3 but not sure, 5 bolts but not t25. Anyway if anyone wants to buy it let me know. It has a bigger compresion wheel than the t25 for sure and the wasted gate seems well designed but other than that I dont know

The comp wheel is smaller than a 2560, I compared a 2560 wheel to the CXracing wheel, didn't measure - cxracing was "taller" than the genuine 2560, but the 2560 was "wider" than the cxracing. It's the same turbo as has been discussed in this thread, however.

It's removing fuel from the T25G-cells in autotune/running richer. This means it is producing less power on the same cells, correct Brainy?

The item in the OP, http://www.ebay.com/itm/New-Design-T...item3f0441846f
As for the top end, it's removing fuel from the top-end as well, but the top-end is way higher psi than the T25G ever ran, so it was still running your basemap.
I'm just going to pick up a 2560 in the future and go full ArTech, it's not worth this headache imo.

Huh, sounds like a dodged a bullet. I ended up loosing $40 on this thing with shippIng charges, and Abe wasnt impressed with it's build quality. The flange it came with looked down right shitty.
And now I have a turbo thats at least at 5psi well under 3000 rpm
see my build thread for what you're missing.

I was wrong, full boost by 2700rpm, 5ish psi as low as 2380rpm. Found a old Greddy log and I was hitting the same 150 map pressure by 3000, so I gained 300. This is a much better downpipe and wastegate setup.
