I've had both the T3 and the K series turbo apart.
Internally there wasn't much different aside from the compressor wheel.
The fins were fewer in quantity and not as aggressive on the T3. This may attribute to the "more Robust" comment as it's just not going to have the same amount of stress on the shaft and bearing as the K series turbos.
I love my T3 yet i have little expirence with the K24. Have driven a K14 and the off idle response is nuts. And that 14 has over 200,000 miles onm it.
See, thar ya go.
To me, the right answer to the question is "neither".
K14 + hot pump = upwards of 30 psi whenever you want, and it's starting to boost at 1500 RPM.
Sell the T3 in any case. The impeller diameters are exactly the same on the T3 and the KKK24, while the KKK is overall a much better turbo. It's more efficient (slightly) and still has better spool-up. A hybrid KKK would be nice if you can't get your hands on a suitable Holset or Schwitzer.
where do you get your information?I feel the t3 is way more robust.
About durability, I really don't know - from what I have heard, both turbos are very durable as there are very rarely any problems unless totally over-stressed. So about 'robust' I don't know if there's any difference.
Where I get my information? Well, I have personal experience on both turbos, and as for the Garrett, on several different applications too.
The KKK is able to make more power and still has better spool-up. The biggest difference in spool-up characteristics is that the Garrett's boost curve grows very slowly above 1 bar (14 psi) while the KKK gives instant response at max boost. Furthermore, the KKK24 is a newer design than the Garrett, which accounts for the better performance, I guess.

A good point. The K14 is again a very modern design compared to either the T3 or KKK24, but it does lack the ultimate top-end power because of the smaller impellers. For a moderately tuned street TD, I think the K14 is just about ideal. But it won't give you 160 hp which the K24 can...
I have a k24/k26 That I built up and never used.I also had the k24 turbine housing machined out the fit the k26 turbine wheel.This is much better than using the k24 turbine wheel and will produce better drive to boost numbers as its driving a bigger compressor wheel.I used a k26 off an Audi gasser?? and used the k24 center housing as the audi's was the water cooled one which have potential issues from what I hear.I think the Audi k26 had a 40-42mm inducer.

Huh, what 'issues' did you hear about the water cooled bearing housing on the Audi K26s?
I have a '86 Audi TQW with said water cooled K26 with over 200K miles on it, and I've bumped the boost up to 1.8 bar last year and it goes like a scalded cat.
I've got an extra K26 that I'm going to do the k24/k26 hybrid thing for my '79 1.6TD and I was thinking obout using the water cooled center section because cooler is better when it comes to turbo bushing life.
If the shaft diameter is the same for both turbos, I suspect the bushings and thrust bearings are the same too. I don't see how adding a water jacket to the center housing could do anything but good to the life of the turbo.
I heard that the k26 center housings can have issues,possibly with cracking and letting coolant/oil mix??This is only somting I heard though!
I have a k26 thats oil cooled only.i thought it was from and audi 5000.
Hey everyone. I'm thinking about putting together a k24/26 turbo. I'm not
sure I fully understand the motivation behind the different variations of this setup.
In what instances would it be preferable to use both the hot and cold sides of the k26 as opposed to keeping the k24 hot side? I was under the impression using the smaller hot side of the k24 would help spool up times and was one of the benefits over just rigging up a k26.
Also, do any issues arise from using both turbines from the k26 in regard to it being a turbo for a gasoline engine as opposed to a diesel? I thought gas and diesel turbos were designed differently so this might be another reason to keep the k24 hot side?
Thanks for the help!
Sell the T3 in any case. The impeller diameters are exactly the same on the T3 and the KKK24, while the KKK is overall a much better turbo. It's more efficient (slightly) and still has better spool-up. A hybrid KKK would be nice if you can't get your hands on a suitable Holset or Schwitzer.

X2 I've used em both on my modified AAZ and like the T3 better. BTW, does anyone know of a modern turbo that will bolt to our manifolds?

Oh, interesting. I love my T3 and have built a k24/k26 hybrid recently but i'm thinking about selling it. Not sure it's worth keeping, and I do love my T3 too.
