I got my hands on a K26 from an Audi 5K and I decided to find out the difference.
(http://www.customgrind.net/K26K24.jpg)
K26 stuff is on the left and k24 stuff is on the right. The shafts are the same size so the K26 impeller will bolt right onto the K24 turbine and shaft. I still havent decided if I want to use the watercooled center section from the Audi or the VW K24 section. Any opinions?
I mocked it all up just to see how everything fits...

The cold side is about 1/2" (whats that aboot 12.9mm?) diameter bigger all the way around and the inlet dosent neck down....

Unfortunatly I wont know how this works for a while since my cylinder head is still being ported.
If someone has a K27 I have the hot side of the k26. I could make another one probably. And it dosnt have a provision for a wastegate...All or nothing boost :D
fspGTD.. Looks like Ill need another kit. Can I get the big orange impeller o-ring and a wastegate gasket too?
Anyone need a Audi 5K intercooler? Make me a good offer.
-
Yeah the k26/k24 setup is a good upgrade when the budget is tight. Don't use the audi's water/oil cooled journal housing they blow. Go for your stock oil version.
-
I didnt really want to plumb all that. Good to know.
I dont really want to sell my children (at least not at the moment) to get a nice ceramic ball bearing hybrid turbo.
That 97 Dodge TD truck has weeds growing around it. I can see though the fender and see whats in there...drat...morals keep getting in the way. :(
-
Yeah I have never had good luck with water/oil cooled turbos, neither has anybody I ever met in the performance market. Plus its just more plumbing. What turbo is on that 97 dodge :D
-
Im not sure exactly but I know its in there...and its calling to me...luring me to liberate it from its tomb and feed it. Problem in they are gluttons...
I wonder if I could shoehorn that 6bt into my Jeep? Actually I know I can..

Mid engine jetta :twisted:

i'd say smack in a second 1.6TD into a jetta, twin engine AWD, sounds good to me :D Dave you know you waaaaaaaaaanna.
-
I've seen some video's of a vw with two engines in it... I think it was a golf. Both engines were turbo's. Too bad the rear engine exploded and who knows if the driver survived :(
Would have been real sweet to rally tho... :lol:
-
Trust me the thought of a twin engine vw has been on my mind for years, but the thing that keeps me from doing it is that I would still be stuck with a vw, I just couldn't spend over 20grand on a vw, I don't care what model or how new it is... Guess I am still a porsche and mercedes guy deep down inside... How about a vw diesel powered 911...
Back on track, grab your head and manifolds and make sure that compressor will clear your intake manifold, I kind of don't think it will, when I did it I had the manifold flipped upside down, I can't remember if this was why though.

I think everyone survived. It was a poor setup. Lots of safety issues that you can see in teh video (for example, no rear firewall, people infront of the car etc) I think his fuel line popped off and well...

Well I guess Ill have to wait till I have my PP exhaust header before I can try fitment.

Gotcha 8) Although you will need to use a normal t3 turbine housing, see the flange I posted in the manifolds thread to see what I am talking about, virtually all t3 turbos except for weird models usually available on production cars (like our vw's).
-
My K24/K26 turbo fit using the stock td exhaust manifold, I had to make 1/4" spacers (exhaust gasket shaped) and clearance the intake manifold a bit.

I guess Ill be modifying one then. Will a t3 housing bolt onto a k24? ( I think I have a few from when I was playing with ford 2.3s)
Were the T3 equipped diesels more common then the KKK equiped ones or something?
-
No its just that all t3 aftermarket turbos are that style flange, the vw flanges are wack, one of the main purposes of making these manifolds is to get people to start using better and more effecient turbos for their setups. Find a turbo from a mercedes 300d turbo diesel, 78-85. Those turbo will work perfect with these manifolds, and they are well sized for a performance IDI. and they are cheap on ebay and wreckers (around $150usd)
-
oh and the vw t3 and k24 turbine have the same inlet flange.

yea the trapizoid.
But yours will have the standard t3 flange?

-
Yep that the normal one right there, the MB turbos have the normal flange, go find one, they are great.
-
Well if I find one Ill do it...but I have 3 turbos laying here that only cost me labor to get.
Other then the kit I bought here from fspGTD.
So if I get a header Im going to have to modify it.
-
Andrew good call man, I starting drawing up and adapter last night that would allow you to use the trapeziodal flange to the t3 flange. I was planning on making the taper for the difference in the actual port size as well, but maybe the best option is to do what you said and make the two extra holes in the t3's inlet flange, and than the buyer can just port their turbo to suit... I wonder if ther eis enough meat ther to do that.
I'll go check, if there isn't enough meat to port the turbine to match I'll continue work on the adpater.
-
Ok just checked, definately no port matching here, the t3 inlet is twice the size of the vw version, so an adapter will need to be machined, it will need to be about an inch thick to match everything up, more computer work... :?
-
Don't ditch the adapter. There's plenty of folks (like me :wink: ) who'd buy them in order to put the T3 style turbos onto the VW flange. I would also change the shape of the header flange and add the extra holes to allow either style turbo to be used with your header.
Andrew
I am gonna go with the adapter, pretty much have to. So the t3 inlet flange will remain as it is and the adapter can go between that flange and the turbo inlet flange :) Sound good? Anybody have anymore requests?
-
that pretty much covered it.
Thanks Libbybapa.
Actually..I was kinda thinking..would it be feasible to make an intake that incorperates an Air to water cooler. Kind of like what they do on the ford Lightnings.
I drive alot so I have WAY too much time to think about crazy stuff.
-
You kind of could, but i have never seen an effecient air/water cooler, everyone I ever met that has tried one (including myself on a few different occasions) always ends up throwing it out and placing an air to air cooler instead.
