Gary,
 I am running a k27/26 #6 and this is my fourth turbo. I started with the RS2
and wanted more so I went to big Garrett's with #8 housings and sure enough
the lag was unbearable. The first one didn't get full boost until nearly
5000rpm and the second one was around 4000rpm. The key with the K27/26#6 is to get
the #6 housing with the 2.2" exducer opening and clip it. Its still a little
laggy with full boost at 3500rpm but pulls very nice all the way through and
will be good for 400+HP (I think)
