I grabbed this on eBay recently for my bike project. It looks alot bigger in person than it did on ebay. I'm guessing its a K03, but the images i've found don't have this 5 bolt exhaust outlet.
number on the compressor: 5304 101 5091F
My bike is only 400cc, so I'm now thinking this is too big. They threw me off w/ the soda can in the pic. I was thinking of something more along these lines:
Anyone have a "like new" IHI RHB3 they'd like to trade for this (probably?) K03? 
You can block off the wastegate, and not have to have such a large diameter pipe. I know there's a lot of subarus that run with the wastegate blocked. meh just my .02 Plus since I just got the zrx, turbo kits have been dancing before my eyes lol.
How do you know its a kkk turbo? Was it wearing a white hood when it came in the box?
Seriously though....
Are you trying to find the A/R of the turbo or what? Honestly, your going to have trouble finding a trubo small enough for your application, 400cc isn't alot to work with. Even the ones on a jet ski are going to be too big for your application. What A/R are you looking for?

If it is a kkk unit is is most likely some variant of a K04

Do a general search on the first 4 digits. I am betting it is from an AUDI. It also looks like some one removed the id plate from the unit.. . Now why would anyone remove the id plate from a unit?. Hummmmmm.
try cross referencing p/n 058 145 703 C . looks like it came out of an audi a4, or vw passat... which would make it a k03.

Extreme weight saving?
I have a bushel basket full of RHB 3's, but I think that's still a little big for the application.
I have a friend with a turbo'd DR-Z 470. I'll ask him what he used.
It's VW 1.8T, Likely 98-05 Passat/A4.
ooh!
According to mjmturbos.com its a K04-18.
Every other K03/K04 i can find has a 3-bolt exhaust flange...

Its missing the exhaust outlet, I think. The area with the five studs should have a cover bolted to said five studs, producing an exhaust flange.
