I have to admit the shipping from China was pretty quick. I got mine yesterday, and I can tell you it looks like crap. As stated above, the finish is terrible, machine marks everywhere but the most annoying part is all the chips inside the threaded holes.
I'll be taking it apart and posting up my findings in a bit.
Here are some pictures.

I couldn't fully disassemble the throttle body, there's a gasket that's stuck inside the bore where the throttle plate shaft goes through, and the stupid spring is stuck.
From a super quick inspection, the throttle plate ranges from Ø64.47MM to Ø64.54MM, the shaft is steel, I just don't know if it's hardened (I have some hardness files around here somewhere.)
This appears to be the bearing: https://www.fastenal.com/products/details/4126357 from the part number

3. Pulleys
The SKUNK2 pulley is a fully machined piece of aluminum whereby the China TB is a plastic pulley. I haven’t disassembled the China TB to look at the internals where the pulley connects to the shaft but I expect the aluminum machined version is a lot stronger. Also, spring pressure seems the same although I haven’t checked with a guage.
4. Butterfly shaft
Here’s where the 2 products differ significantly.
Cross shaft Ø:
SKUNK2 10.88
China TB 9.71
Across shaft flats:
SKUNK2 6.8
China TB 6.8
Here are the dimensions I got from my shaft.

I got mine the other day- took 7 weeks and at one time was thought to be lost. Anyhoo, it looks pretty good. A little different than the others, machine marks were acceptable and the throttle cam is aluminum not plastic. The throttle shaft also measures about 10.5 mm in dia. Raw aluminum it looks like. I did not see any color options at the time either. Trade me for that black one?

Word of advise to anyone who hasn't installed theirs yet. Bring your idle control valve with you when you go get the button head screws. They only supply one screw and the other will need a slightly longer one than whats on the factory TB. Also the supplied TB to manifold gasket is cut wrong.
