Haha, your ignorance is forgiven, simply because I had a great laugh at that one. 
It's all good 
Heh, anyways, K16/24 means you take your stock K16 turbos and have K24 compressor wheels installed on them - somewhat known as "zero clearance" turbos. The compressor wheels cause even greater airflow.
So basically you change your two K16s into two K16/24 hybrids.... OR you can just buy two regular K24 turbos and be done with it (which would be the "K24 setup" (K24s come off 996TT X50s, 996 Turbo S's and 996 GT2s) - kind of what you meant in the last part about 24/24).
Make sense? heh

everything is correct except the zero clearance part. That is something totally different. You can have K16/24's with or without Zero Clearance. ZC is much more expensive.

K16/24 should spool faster , less lag compared to K24, espacially zero clearance one.

Looking at your dyno there's a big increase of power at 6200-6300 rpm to the red line ... looks that you have a great increase of the boost in that rpm range !

Call Kevin at UMW- he is the zero clearance guy.
The FPR takes about an hour with small hands and an iron will. Look over on Renn- Mike Kelley did a perfect write up with pics. Walked me right through mine, bolt by bolt.

That's true, but the straight K24s should flow better up top, so k16/k24s are good lower end, really fast off the line turbos, while the K24s are better on top end.

Do you have a link?

Zero clearance is expensive, but it is worth the extra to do it. I have it on my turbos and I boost from 2k rpm bog. pretty amazing. Before that my k16's would not really boost till about 2400 or so. So I have more air flow and better spool up. And the faster they spin the more efficient they become because the blades expand and get closer to the ZC material making them more efficient. So at full boost they are even more efficient than at low or beginning boost.

I did a DIY and posted it here and also on Kevin's site, but you'll have to search for it...
The K16/24s, along with the following will surprise most:
Diverter Valves
5Bar FPR
Upgraded wastegate springs
Upgraded boost hoses
Speedtech 70MM exhaust
This combo, along with a good solid tune from someone like UMW will net you an EASY 625-650 CRANK HP on 93 Octane. But budget for a clutch upgrade at the same time, as any good tune won't hold the stock clutch with this setup.
I've got a BUNCH of GPS verified track data (Traqmate) that isn't recognized here, but this car flat flies and I've not run into ANYONE on the street on a motorcycle or in a car that has "hung" with me... And on a road course???
