That's why I said "done recently". My motor is the standard turboR , circa Q1/08. I didn't ask for anything custom, nor was I offered any choice in the matter. I did enquire about getting something similar to what LeonS has, but was discouraged of it, as I was with my central exhaust question. I only found out about the turbos by specifically asking about them. Paolo (pmf) and I were exchanging emails at the time, since his car was there as well. We were both told the same thing - K24's on one side and "something else" on the other, keeping up the Ruf mystique. I've never seen more than about 15 lbs on my difficult-to-read Andial boost gauge. They're sold as having 490PS and 650Nm, 'cos that's the number they guarantee. Results may vary, etc., etc. Both our engines produced noticeably more than that on the Ruf engine dyno. 
So seems they are only doing a K24 version now ? Is it possible that the K16 version was developed before the K24 platform was actually available (it came in around '98) hence the K16 hybrid was state of the art at the time but now the newer K24 based stuff has so many more advantages hence it is the default choice ?

TurboR's done recently have K24 based turbos.
I wouldn't be laying that down in concrete until you can verify it physically by measuring the parts!
I am in no way stating that your turbochargers don't have K24 parts in them, but to say that they are all K24's is 180 degrees opposite of the norm from this tuner. To be more specific I would be looking at the turbine housing casting.

Hypothetically speaking, is it possible to get 520 engine dyno bhp using a single plug 3.6 litre engine running hydraulic lifters (any cam) and no more than 1 bar boost without using K24s? (let's assume we stay with KKKs)

I have NOT seen any K16's or K24's break 520HP staying at 1bar.. You can't do it with the 996TT platform. I have seen it done with dual K26's.. But the powerband was north of 5000 RPM's.
SINCE your Edit> It might be possible if you raised the RPM to 7800 to 8000RPM's and a Race camshaft.. Anything is possible with $$$$. The hydraulic lifters will be suspect. But then with $$$$ to spend one could build custom rockers and lifters. Or skip all of this and install a detuned 962 air-cooled engine with dual K27's.

The KKK24 turbos will flow around 26-27lbs of air per minute at 2 bar absolute. This will put a 993TT engine at around 460-480hp at 1 Bar of boost..

I would not be surprised if RUF started using K24s on the newer conversions, this means they would have also reworked the mapping of their ECUs. On the other hand this could be unlikely in my opinion, as it was a proven package, and IMO their most succesful one...ever. I think what they mean by "based on KKK24" is what Kevin meant, KKK24 compressor housing and KKK16 hotside.

To the best of my knowledge, and I have some as I have been hanging around Ruf in Germany for over 4 years.
Jean you are correct on no changes. Once they have a package set they don't like changes so I would bet on it remaining the same. Ruf also gave up R&D on the air cooled packages with the advent of the R Turbo, 996 base.

LAT I'm pretty certain it is a "new" package, Adam T who worked there as a student for a while did state they had a "520" package as well as the regualr "490".

I thought the stock CTR2 package was external an wastegate K26 or K27 type blower with a hybrid adjustable (fixed) boost Motronic system, not the same as the package bb993 has ?

The stock CTR-2 is an external wastegate k?? package, I did not say the 520 HP uses K24's what I said was they have a 520 HP package.
I don't know of a 520 HP K24 package that they have however if we really want to know I can call and verify what is what.
