or a rebuild K03/k04 hybrid


the numbers on the compressor housing are similar to my K03, except for the 2 next to the triangle. the k03 has a 1.

Someone sold this to me on here, and it only lasted a couple miles, going to get it rebuilt, but im starting to wonder if it was really a k04.

Well, i don't know the answer, but this is my BW k04 from CTS.

I'd get a k03 and put it next to it for sizing. If you paid for shipping I'll even send you one if need be. It's busted as f*ck but that doesn't mean it's a different shape or size or nothing. Makes a great door stop.

it looks smaller than the second picture to me

it looks the same but because of the black wastegate and there being no tag on there stating what it is, it looks just like the chinease k04s on ebay, they have hybrids and regular k04s that have the black wastegates and they dont have the tag either, but im not 100% sure.

Put it next to my k03 the inlet appears to be the same size. How much of a difference is there between the k03 and k04?

The wastegate is a different color because of a rebuild. They painted it. But they also ripped off the serial tag.

might be a gpop hybrid

the inlet size will be the same, its the pitch and design of the impellor that makes it a ko4 also the exhaust side is a little different and helps exhaust flow
