Oh great! About a minute before I got this message I managed to send one
to the list asking about Garrett information and K26/Garrett hybrids. :P

My timing is way off this week.

I'm basically interested in the Garrett terminology, all this trim and T
thingies. :) What do they refer to?

I was also wondering how a T4 cold side would work on a K26 hot side. I
still want to go measure and calculate the A/R of the K26 hotside.

Only reason I'm beginning to look at this kind of hybrid is that I'm not
finding any K27 cold sides over here as easily as I thought. :(
