He wasn't interested in shipping to USA until I offered $550 shipped. closer examination shows it was resealed with silicone and had a chipped cold side housing. I lost interest quickly lol. I am interested in any used turbos anybody might have. I may have a bad k26 off the parts car here that I wanted to send out for the billet mod. It's missing the freeze plug and has rust on the chras and inside. Spins fine tho?

[88a5tq]

He was asking about 360 euros with free shipping within germany BTW. Not really worth it for me when I can get one for a fifth of that price I offered (thinking rs2 at time!)

[loxxrider]

lol yeah, not good! I think if that turbo you have is a good core, the billet k26 is a really nice option...

[PRY4SNO]

A little birdie told me there may be a hybrid k24 hitting the market in the near (ish) future...

[88a5tq]

That sounds interesting. Does this -ish happen to mean in 14 or less days lol? I'm finding it already difficult to wait to upgrade as it is Iroz maybe or Marc?

[PRY4SNO]

You're on the right track... but not sure on the release date.

I've asked to be put on the list for testing when they're available.

[88a5tq]

THERE'S A LIST!? Lol I bet I'm not on it I might be on the brown colored list tho

So I see other billet k24 options.... even for KKK turbos. I wonder if the $160 I saw for impeller could score me a "universal" one that I could install with the turbo still on the EM? I have 2 k24's, both on motors (one running) and the same for both k26's. Part of me just wants to put the billet wheel on the original k24 without all the hassle of removal.

I know, they're for 04 to 09 volvo but I just want it to work! The advertised hp gains are trash tho..

The housing has to be machined to fit the bigger compressor wheel. So it's not quite just a throw it in and go type thing. Wait for a proper turbo for a proper upgrade. You'll need bigger injectors to run a bigger turbo as well.

[88a5tq]

I have rs2 reps right now. The billet k26 doesn't do it for ya? I think it's good for 400 chp

[pilihp2]

The rs2 reps are good but not enough for something properly sized. The billet k26 is cool too, but I believe Hank has stopped producing that billet wheel.
Any of the billet turbos, k24, k26, and rs2, all require machining the compressor housing to fit the bigger compressor wheel. So it's not easily doable in the car, plus it'll need to be balanced as well as the seals replaced. So unfortunately, bigger turbo stuff isn't always super easy.

[88a5tq]

Well I hope he's not done with it. I'd like to retain everything I have minus the k24 right now. For simplicity, I'll keep the exhaust as is by using a k26 flanged turbo. I don't want to replace my oil or coolant lines either. I'll figure it all out eventually.

As for the turbo staying in for the billet upgrade, I was just thinking wishfully. I realize it's extensive work. Just being light-hearted about it thanks for the advice

[PRY4SNO]

From my understanding, the newest iteration of the k24 will be a hybrid, not a billet wheel.

But I've (probably) already said too much!

[88a5tq]

a sale is pending for me on a k26/to4b right now. I'm excited. Also that leaves my k24's available for future hybrid shenanigans. I have the week after next off and turbo oil seals were ordered yesterday b4 I even knew I was buying the turbo lol. I had a gut feelING I guess. I wouldn't mind throwing a k24 into the 5k at this point tho keep me updated on developments with that grapevine info

[loxxrider]

Nice, I'm curious to find out how you like that turbo.

[88a5tq]

This is what has me excited:
Full boost by 3500, good useable boost from 3000 or so, I made 375wheel hp with one of these on my 20v, a 20v will make a good 300whp or so no problem, assuming you have the management to back it up.

Thats from javad on mg a while ago. With my meth injection I expect to reach the limits of my block. Hope I don't exceed it LOL. Yep I'll definately keep this updated

[DE80q]

I'm glad its going to a good home. I have been watching this thread for some time now. One thing to remember is, this is using a Porsche K26/6 turbine. It may run out of breather on the high side, but should should spool up quite fast.

[88a5tq]

Thanks Dave. I will post up some logs once it's moving along. I'm getting hyper just thinking about it lol. Installation begins friday!! Thanks for reading all this time Dave.

You're right, kinda spaced on that one.
New one isn't even quite in the same ballpark as a standard k24 7000. Can't just throw a wheel on it.
My previous statement still stands for a k26 or rs2/k24 7200 though.

Lips sealed!

[88a5tq]

So let's extrapolate for a moment. I'm pretty positive, like HIV positive, that I'm making about 300 chp on my poor k24 at 27 psi from 3800 to 5400 rpm. I w/m has good part to do with that maybe. So with the turbonetics compressor what do you guys think I could possibly see. Let's just be hypothetical here. I'm not gonna pm you guys demanding my extra 23 whp in blood or what have you.

[88a5tq]

TBH tho it feels alot quicker at redline after the pressure tapers to 19 psi. I believe that is due to the higher V.E. from the cams.

Is the only difference between a stock k26 and a larger GT turbo the amount of fuel added in the tune? That's where the hp/TQ increase come in? So if the GT runs 17 psi vs the k26's 26 psi, the GT will create more dense air charge which will require more fuel.

I guess I'll need more fuel if everything is going as expected right (With the hybrid)? It CAN'T be nearly as inefficient as a k24 above 16 psi! I saw on the q list that it's absurd for the k24 to be expected to put out over 16 psi without be overspun. If that's true, I'm doing that every time I put down the smoke pedal

[pilihp2]

More fuel will definitely be needed. Your power band will shift as well so timing adjustments might be needed depending on how much it shifts.
Not a clue on power levels, but if the t04/k26 is about the same as a volvo k24 as I think I saw claimed, you will be very able to send a rod out the side of the block. So BE CAREFUL. Limit your boost, get bigger injectors, listen for knock, play it safe. It might be able to do 400hp+ at the crank without blowing up, but reliability will definitely decline over time with that much power on a stock bottom end.
Forged rods and a bottom end rebuild should be in your cards in the future if you really want to push the power.

[DE80q]

My claim was it SHOULD be similar to the Volvo K24. I have no solid proof of this, but with looking at compressor maps of various t04b's along with the turbine specs of the K26/6 I would be fairly confident you could break the engine. I would turn down the boost levels to near factory, and start the tuning process over. Don't try to push things to much too fast.

Philip, I thought the factory internals of the 3b were all forged?

[88a5tq]

Oh wow when I first heard the k24 reference I forgot what I'd read about it years ago when researching for the 5k. I guess I figured it couldn't be much better than the audi k26 already. Well for now I'll just shoot for rs2 levels with my current injectors. For safety reasons in the very least..

¿I also thought I read 400 whp was the limit?

[pilihp2]

Proof or not, I'd imagine your numbers to be closer than just guessing. So if we were to say it was close to a volvo k24, it could blow it up with ease.

Let me be a little more specific with my rods comment. Aftermarket forged H or I beam rods, not stock rods, should be in the future.

[pilihp2]

The block limit is usually rated at torque levels, but the typical level they blow at are around 400CHP-ish, depending on turbo spool, torque spikes, detonation, and other variables. A good number to shoot for if on stock internals is 350-ish-WHP.

You could run a very large turbo on stock rods and might have more luck than you would running a smaller turbo, with less power. From everything I understand it's mainly fast torque spikes and detonation that the stockers can't handle.(keyboard warrior, not a ton of hands on experience with blown blocks, just lots of down-time use at work and attached to my computer at home)
