K26 Turbo?

Hey all,

I had a question for fellow list members. On a 91 20V turbo, is there a
benefit to putting a K26 turbo on when doing a chip upgrade? It seems to
me that the stock K24 (while providing excellent spool times) is getting
pretty inefficient at the higher boost levels seen with chips/springs.
While the K26 isn't so great as the RS2, I just happen to have one.

Here's my thinking. I have an 87 5KCSTQ that I'm planning to do the 034
EFI setup on when the stage IIc is available this fall. I plan to run a
T3/T4 hybrid turbo on that with a coil-on-plug setup. At that time the
K26 turbo from that car would be sitting around. It's in great shape
too. Are the water/oil lines, and exhaust flanges compatible between the
K24 and K26?

If this is a good idea, then I'll have a nice K24 turbo sitting around.
That seems just about right for a 1.8L DOHC VTEC in my civic hb. :o)
Plus, being water cooled too is a bonus.

Anyway, if anyone can shed any light on this, I'd sure appreciate it.
