Author Topic: T3 vs K24 (Read 8781 times)

Oh, im sure this has been discussed tons here, but i cant seem to find anything on the subject. Im sitting on a T3 and a K24 turbo for my rebuild, But i have to sell one to get some money back. From what I can see the K24 seems to have better flow potential, but looks a tad smaller. The T3 looks a tad bigger, and better made, but looks like its restrictive which may remove any advantages. Im looked to squeeze out every last drop of power. Any help on the subject would be appreciated.

if you want ALL the power you can get sale the t3 and get a K26 and make a K24/K26 hybrid..... :lol:

exhaust of the 24 intake of the k26? There is a used k26 on ebay for $86, This could be a doable idea.

The 26 cold side bolts right up to the 24 center section.

Both 53 willys and i are running one as are a few other members.

how much more power does this give? The only thing I am not sure of is since the 24 has the built on wastegate and the k26 does not, there is some plumbing to take in account for (I dont have my turbo's on me currently). Is that not an issue?

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.

The wastegate is not a problem, just use the KKK 24 turbine with the original W/G . As for power, it will greatly depend on what kind of KKK26 cold side you use (there are dozens of different sizes and specs), but a stock KKK24 has been proven to make over 160 hp in ideal conditions. So it's gonna be able to do better than that!

This is the one on ebay (if someone else nabs it i will be sad). This sounds like the way to go then. I was just worried about the hose from the cold side that runs to the wastegate, as this one does not have that. I suppose its nothing that a turbo shop couldn't do for me anyways. If I was to get a rebuild kit... Would I have to grab both then? The add says this is off of a porche 944

No, you would only need the KKK24 service kit, unless you were to use a KKK26 center section.

A KKK26 out of a 944 supports about 270 hp on a gas engine, so that should mean something in the region of 200 hp on a diesel engine.
Maybe the hybrid would have a max output of around 180 hp? You never know until you've tried it, but maybe it'll be in that ballbark.

I got my k26 at a local junkyard for $60..then I paid $100 for a rebuild kit...then I paid $80 to have the k24 housing machined to fit the K26 exhaust wheel...
i'm pretty happy with it...although I dont have much time on it yet..

So, in order to match them up, it does require machining of the k24 housing? I dont know of a local place i trust that does that.

No. That's only if you want to use a KKK26 hot side.
If you use a 24 hot and center section, you'll have your hybrid by just bolting on a KKK26 cold side.
The 26 that you mentioned, BTW, would suit this quite well as it's not the bigger '89-'91 944 Turbo's, but the earlier, smaller one (!)

Well, I bought the K26. Guess that answers my first question, and cost me more money

Now I need to sell my spare TD kit.

Thanks for the quick input guys!

I should just move my build thread over here, i'll get alot more imput from you guys.

Sounds like you'll have a very nice turbo set-up on your hands!

where do you get your information?I feel the t3 is way more robust.
