Does anyone know where I can get quality comp wheel for my GTB2260VK?
Thank you!
Thank you!
No no please do not take offense, I was not attacking Turbo Lab. I was in a hurry and did not elaborate. In fact I will try to get back to them tomorrow. Let me explain so everyone can see where I am coming from and it may possibly help in the long run...I must have misread your original post, post#1 asks about a comp(ressor) wheel, and the subject changes to turbine wheels and shafts. Or was the comment in post#6 an attack on Turbo Lab America?
Hi yes I just now found your message. Thank you so much that is very kind of you!Hy Gordon, I already replied to you on Facebook Message.
Maybe I can recommend you or help you finding someone local, I have seen now you are in Cypress CA and will reply to you as soon as I have something for you.
Yes thank you I am looking at that as an option as well. I have been reading threads here for hours on end trying to learn all I can about this. I have read about the 6+6 vs 11 blade wheel and I am still not sure which may be best for my setup.Could buy a billet wheel off ebay and get it balanced by a turbo builder , https://m.ebay.co.uk/itm/MFS-60mm-1...sor-Wheel-gtb2260vk-tdi-1-9-2-0-/292310613747
I made a mistake, their website does list them in VA. I have been searching and reading so much stuff on so many sites lately that some of it is a blur. Austin and Ian our their names. Texas must have been something I saw on another site I was looking at and somehow Austin Texas stuck in my headIIRC, the 6+6 blade configuration will give earlier spool, but the 11 blade will make more boost--albeit later in the RPM range. So what do you really want your engine do is the real question: red light killer or top end runner? The shop is owned by two brothers, Austin and I can't remember the others name. They bought a new building in a different location last year, but i don't know if they have moved yet or not.
Here is the assembly of my personal turbo:

He does install the heat shield backwards in this video, but he did fix it.
There are tons and tons of TLAmerica videos on YouTube if you have the time.
The Audi GTB2260VK has "only" 45mm turbine exducer, not 46,6mm. Inducer 50mm is correct.Turbo Lab responded
"think that turbo already the largest turbine which is 46.6 by 50. The compressor wheel can be upgraded pretty large though"
Where do you source these high flow turbine wheelsThe Audi GTB2260VK has "only" 45mm turbine exducer, not 46,6mm. Inducer 50mm is correct.
There are 2+2 more options to this TURBINE specification.
50/46mm (BMW GTB2260VK) and
51/49mm AMG GT23
Those two are also available in a light weight high flow design which gives faster spool and more top end flow.
They weigh about 20-30% less than the original GTB turbine wheels, and especially compared to the "head heavy" AMG turbine there is quite some advantage in spool and transient response.
Regarding the HP numbers (conservative spoken)
OE GTB2260 Audi is good for about 300-320hp
OE GTB2260 BMW up to 340hp
AMG turbine up to 370hp
The high flow versions add about 8-10% top end flow.
In terms of compressor wheel choice you are almost "unlimited" from standard 44,5/60mm OE wheel (which is not a bad wheel!) up to standard size billet versions and bigger size billet versions, plus all the different geometry designs and blade numbers....
These are rough numbers, as results always is greatly dependent of compressor size, engine size, engine setup, supporting mods, quality of the software, accuracy of the dyno and so on....
For 190-195hp a GTB2260 is way to big.
You sacrifice low end spool and transient response for a non used top end power capability...
If you aim for 190-195 WHEELhorsepower, take a GTB1756VK or even a GTD1752VKLR in consideration.
Especially the GTD1752VKLR gives a huge load of torque in lower rpm and has great throttle response, its superb for a daily driver....
I am not really aiming for 190-195hp, I just thought that that might be all my motor is capable of in stock form. I want to stay with the GTB2260VK and get as much HP I can without risking blowing the stock motor, which I think is possible with I good tune.For 190-195hp a GTB2260 is way to big.

You really think I am going to share my manufacturers?Where do you source these high flow turbine wheels
Sorry, that was the auto correction on my cell phone....VRK is correct certainly!what application is GTD1752VKLR, I have only seen a GTB1752VRK so fare...
Listen to Dave:I am not really aiming for 190-195hp, I just thought that that might be all my motor is capable of in stock form. I want to stay with the GTB2260VK and get as much HP I can without risking blowing the stock motor, which I think is possible with I good tune.
So now what I would like to do is see if I can is upgrade my turbo with the AMG turbine high flow version and a Billet Comp Wheel. I am not sure which size wheel to go with but I think the bigger I can go and see gains would be preferable as you never know, I may decide to pull the motor out and shot for even more HP. It's not what I want to do right now though.
As long as you are not going to "crazy numbers" far above 300hp, the GTB as is is totally fine, as stated above, the OE compressor wheel is a good design and the 45mm turbine can flow plenty for that compressor.How about just leave the GTB2260 you already have alone???

Yes you are 100% correct, WTH was I thinking!! Sorry about that!

Yes I agree. After reading non stop for weeks I am sure the turbo can provide more then enough for my motor. I would like to do a same-size Billet wheel for a couple reasons. 1) I think it may be a tiny bit more reliable. 2) I would like a shop to have a look at this turbo. My friend that I got this turbo from claims it is brand new, and it certainly looks brand new but it was not in a box and it was missing one of the housing captive washer bolts. He claims he robbed it for another turbo and never got around to replacing it. He did give me a proper bolt but it is not exactly the same as the others. It is a peace of mind thing for me
I hope you are not sleepless because of the turbo spinning your brain
Yes, I think I have slept a total of 5 hours since last Thursday evening because that is when I started my short vacation
I have been searching and reading everything I can find regarding this modification and my car. I am trying hard to educate myself as much as possible. I am trying hard to help everyone help me and hopefully someday I can help others
I do belong to some motorcycle forums and there it would be me giving answers and not asking questions because that application I know well. So I know all to well the more info an OP can give the easier members can help!

This was not pointed in your direction, as you did not ask this question ;-)
No reason to apologize for you here!
