Anyone know if these are any good?

Compared to that of a stock TII turbo, how would they perform, better/worse?

Spec sheet is here:

I plan to put it on my NA, providing it is half decent.

Their used on 4 cylinder turbo diesels; a bit small.

FYI Porsche 951's came with the KKK-26, and 996 911's ran dual KKK-24's.

Do you know the specs (or where I can find a compressor map) for the stock TII turbo? Obviously mazda put a lot of time into finding the right turbo for the job. I would like to compare the K-14 to this.

Take a look at the map and let me know what you think. I did some basic calculations (CFM, RPM etc) and figured Id need somewhere around 0.15-0.18 cubic meters/sec at WOT @ 8000rpm and 0.05 at 3000 RPM (when I want the turbo to start boosting). Taking those numbers to the map, they fit pretty nicely if you plot those two points. They are basically on the turbo's highest line of efficiency. However, this map is for the turbine (compressor) side, and not the exhaust side... What I am worried about is getting WAY too much boost, or in otherwords, that this small turbo will be a huge exhaust bottleneck.

No.
Mazda did not release such information for public consumption.

A little off topic.. But thought you would enjoy the video, A Diesel Rabbit doing an Auto Cross event... vid is 7min long. he does 9 runs, has a camera inside the car too.

You mentioned the KKK is from a VW diesel.. I had an 84 Quantum TD.. It also had a KKK But it was not a KKK -14 Bigger I think... I used to push 12-15PSI all the time, and after cracking the head, I had some fun and turned the fuel all the way up... Not sure about peak boost.. cause it was off the dial... well over 30 PSI... LOTS OF SMOKE TOO!!!

I have several different car passions.. Diesels, Rotarys, and Turbine related stuff..

Kinda funny.. Diesels, and Rotarys are like oposites.. Rotarys REV, have good HP, but low torque, Diesels DO NOT REV, have low HP, but BIG BIG Torque. And Turbines.. well they just sound amazing.

Since you're talking turbo vw how about this one http://media.putfile.com/5th-Gears-N...Wizards-of-NOS

That was SWEET !!!.. The car and the chick... Love the British accent. I cant believe it ran that well compared to the NSX.

On other mod you can do is to introduce Propane to the intake. It will not ignite prematurely on the comression stroke.. But it is set off when the diesel ignites... The propane adds some fuel, but it really helps to burn any diesel that has not ignited. In the older diesels.. the cyl walls are much cooler than the air at TDC.. so what can happen is that small amounts of diesel fuel condense on the walls, and dont burn completely.. the propane stops this.

Now we just need a Turbocharged Diesel Rotary.. and I can have my complete engine "Fix" all in one.

Already did some reading on the possibilty of an diesel rotary..... I think it could be made to work... But I had not considered the fact that to increase commpression, you fill in the bathtub.. hence reducing the air intake charge.. hence reducing compression... kinda a problem... The right turbo setup may help.. also modern common rail injected diesel only run at 14:1 commpression... so maybe there is some middle ground where it would work.

Effieciency would be great.

Well.. I rambled on.. WAY to much.

Have a good one.
