I got this beast for free and I'm having trouble finding any specs on it. things I do know,

It's a KKK somewhere near or around a K27

I don't know much of the KKK turbo's or have documentation, but if you'd pop the front and rear covers off and measure the major and minor diameters of the turbine and compressor along with the B-width (tip of the comp and turbine blade width at the major side) i could give you a rough estimate of power potentual. Just from your pic of the caliper on the inlet, it looks to be on the small side and the fact its internally gated. lastly, what kind od foot print does it have on the turbine flange were it mates to a manifold?

Give or take a little these are the measurments I got.

I'm not that knowledgeable about turbos yet, but hope to be. I have been reading the forums a lot and learning a lot. Here is a pic of the foot print.

It's pretty small as I thought. Your compressor compares roughly with a T4 T04B Super V trim and the turbine is between a T3 stage III and a T4 O-trim. The turbine flange is a divided T3 footprint just from the pics, or some KKK proprietary design. This would be a great turbo for a small displacement to larger 4 banger, its pretty small for a rotary for any type of power. I'm guessing 300 ish and it'll be off its main efficient map islands. I say ebay it, should get you a pretty penny seeing as though it’s a KKK, the VW guys should eat it up.

Mike, Thanks for all the help. To ebay it will go

Actually, its closer to a T04E 50 trim then the T04B Super V trim. I say this because it seems to be a newer design compressor, which is more efficient then the older T04B designs. So, in your listing, make sure you don't give my power figures, as this is a rotary application. It would make more power on a piston engine and would also be able to run higher boost before running out of puff. This is mainly speculation because I don't know exactly what KKK turbo it is and don't have a compressor map in front of me, I'm just going on your measurements and visual cues.

So, in your eBay auction, I'd list the following:

KKK turbo of unknown model. (I would list all the markings you find on the turbo here and say were the markings are {EX: tag on it says.........., compressor housings says ........., turbine markings say........ etc.})

Compressor side (cold side):
Minor DIA. (inducer) approx. 2.11"
Major DIA. (exducer) approx. 3.03"
Very close to a T04E 50 trim in dimensions and probably flow #'s, maybe more due to the larger compressor housing.

Compressor housing has a "ported shroud" to prevent compressor surge and makes a cool whistle noise when boosting.

Turbine side (hot side):
Minor DIA. (exducer) approx. 2.40"
Major DIA. (inducer) approx. 2.75"
In-between the biggest T3 (Stage III) and medium T4 O-trim. BIG for a 4 cylinder for BIG power.

T3 divided turbine footprint.

Internally wastegated. unknown boost/spring pressure.

You might want to put the inlet diameter here (the outer most diameter were you'd put on a rubber coupler) and the compressor discharge diameter as well. The discharge is a V-band style and not meant for a rubber coupler, but could be grounded/sanded smooth to be able to use a coupler.

KKK I believe does not use the A/R method as others (Garrett and Garrett clones/derivatives), so I don't know what it would be comparable to.

Good luck, post a link, glad to be of help.

Seveninphilly,

I edited my spelling and added info, so if you copy and pasted this earlier
into a eBay add, you might want to go back and re-copy/edit it.

Holy crap!... Thanks Mike that is above and beyond!....Your help is greatly appriciated. I can't believe you just wrote me a whole description.

Quote "Compressor housing has a "ported shroud" to prevent compressor surge and makes a cool whistle noise when boosting."

Can you tell me a little more about this how it works theory behind it?

I will post a link to the auction when I get it up, I have been so busy with other bs my car stuff is getting neglected, But not for much longer Whoo Hoo.


Thanks Again
