[s-cars] Combining Turbo parts?

[qshipq at aol.com]

 The only part of a k24 that bolts onto a k26 (or vice versa) are the cold side housings.? Both the hot side wheels are attached to different sized shafts (k24 = smaller shaft), so they are not interchangeable, and by definition neither then is the cold side wheel.? The hot side housings are not interchangeable without machining.

The RS2 uses the larger k26 shaft, a k24 cold side housing and a k26 machined hot side housing with unique hot and cold side wheels.

Is the combination of K26 hot side with K24 cold side a good way to go?  Any
BTDT/experience on this.  I'm looking at some options to refresh my engine with 
a stock
turbo configuration.   I have a hybrid turbo (T3/K26) and have had nothing but 
problems
with keeping the lines and fittings from leaking and now it is blowing oil 
internally,
so would like to get it back to using some nice OEM lines I have.

Anyone care to refresh me on the pros & cons of using a k26 vs k24 on 20V TQ 3B 
engine.
Would doing the above be better if I have a K24 and K26 to spare?  My basic
understanding is that the k24 spools up much quicker, but become inefficiet at 
around
300HP or so whereas the K26 takes longer to spool up but has more headroom.  
Anyone know
where the K26 begins to die?

Anyone have a KKK rebuild kit laying around in case I decide to do this?  Any 
caveats in
separating these and rebuilding, resealing, bearings, etc.

Ben
