I've been running various KKK-turbo's in my Porsches and the latest in my '82 911 RUF Turbo is my all time favourite:

The engine is 1989 930 with multiple modifications:

-RUF build Turbo engine with KKK-27/32
-C-group sylinders and pistons
-B-group 12plug-heads and camshafts
-3 oil coolers in front
-RSR-ingnition unit
and much more.

The most important thing is, that by having very reliable racing engine (even under heavy foot and high boosts) now it really starts to work early (in 2500-2700rpm) and keep especially the Nm nicely up all the way to 7300rpm (the engine can handle 7900rpm). I prefer it a lot, because I have 4 very long gears in my shortcase (4th can theoretically carry me up to 345km/h with 7500rpm), the fastest GPS result so far has been 322km/h and still having 3,7sec 0-100km/h with first gear.
The engine with 27/32 push nice 580rwHp and +600rwNm with 1,2bar. It can handle much more (we have a dyno results of 1,8 bars), but just now the engine gives the best response for track use handling and still nice " drop dead" street acclelration
When playing with very well breathing turbo engines be sure that your waste gate and dump valve are working very sure and properly and you easily save an angeine or two. BTDT.
I have altogether an old school Le Mans combo build with an old fashioned 935 dual waste gate with 0,6bar spring. This is the setup for my wife (although she rather drives 951) with 460 rwHp with it.


In my 951 I have also dual waste gate with 0,8bar spring and KKK 27/28 with many other engine modifications and I prefer that also (with 337rwHp / 470rwNm/1,3bar ) and I really studied that rebuild your engine thing twice .
My winter car Ur-quattro kicks out 428 rwHp with considerably large Holset Turbo and very high 1,8bar boost. This one my wife doesn't like at all.

Still I prefer most my 911 with KKK 27/32 .
