As i have tried a few, i would avoid the 2565 version. For drag racing it should be ok, capable of 400+hp
On the street instead it's not good, way too big and spools to late. I had the upgraded version 2565vklr ..1 big useless turbo for a street car.

A friend is running r520 nozzles and 11mm pump with his 2260vk and it runs really good.

Well my golf I am building I have .460 nozzle mounted on my injectors as per darkside. We decided to go with the largest ones Incase I upgrade to >11mm pump and want to make more than my desired 300-320hp goal.

Sure you can use that size nozzles.
With 11mm pump 0.320 can make something like 350-380hp. 0.360 makes like 340hp and 0.460 something like 320hp max!
11mm can handle 6500rpm. Do you really want to go 12mm and gain... nothing ...and adjust limiter to 5500rpm?

I got 12mm pump, i got RC7 and my tune goes to 7000 rpm, so .0320 would be the way to go right? thensorry for my ignorance but who makes these nozzles? bossio? and where do you get them? are they Chinese knock off?

Where is this information from you are stating? I’m not doubting you by any means just wondering. I was once told I cannot achive my current goal unless I went compound turbo which I know now is wrong. And was told the 11mm pump would only be capable of 220hp which I also know now is wrong...

are you kidding me, 220hp I accomplished with 17/22 turbo, 2260vk man you can go wayyy more than that, of course with right tune and injection, my car goes like a raped ape, I want to change the nozzles cause the ones I got they just dump fuel and it is too smokey at the begging before spooling,, are these 0.320 nozzles legit? not Chinese knock off, the least thing I want is to melt a piston with them, pls chime in

you got to do miracle modifying an engine with 10mm pump and getting it to 300hp, I would imagine that would be the choking point (bottle neck)for fuel, a big starvation will take place.

We got +38bhp with simple pump voltage mod with 11mm. Same things can do with 10mm.
We now run our 600kg class compact diesel tractor puller with 11mm pump and 0.320 nozzles. Those fuel levels can spool our turbo with 60mm compressor wheel. And that 60mm is not compressor exducer like gtb2260vk, it is size of compressor inducer!

I am running the 0.460s now w/ 12mm pumphead.
Compared to HFLOX 0.341....not a huge difference, but more torque.
12mm pumphead + 0.460s is a lot of fuel and EGTs rise quick.
50mm inducer hybrid isn't terribly laggy if you have plenty of fuel.
Not really the best combo for street & traffic. Out in the country, yes. City, no.
I agree 0.320 - 0.341 should be max size unless you plan on nitrous

I'm trying to make the 2260vk spool faster a good source is going to build a gtb2560vk for me with the new generation blades and billet, 60 mm billet and inducer on the 22 blade (49/51mm) will be lighter, stock is 185grams 25 blade 133grams, basically being a guinea pig , according to builder 2560 turbo should spool faster,,, I'm trying to get me a nice nozzles to go along with it, so I can try turbo, and if it does not work then I put my old 2260vk back in my car.

Well the 4951 turbine wheel is a bad choice to start with imo. Just removed one from the car as it has **** spool on CR without smoke, and smoke doesnt help either.
Its just too big with too much flow.
The 4650mm light tw on the other hand its so much better, i am using it now and its superb. Best turbo i ever had.

As we know 12mm + HFLOx 0.341 can deliver fuel for approx. 460bhp (NOS result). How much your goal is if you really need 0.460 Nozzles? Do you are satisfied how those nozzles work in normal driving situations?

did you have the right fueling with the 49/51 blades on that turbo? so you had no smoke and that's why was bad? how did it spool?

His spool was too slow...and even with additional fuel...it didnt get much better. Night and day the difference between the two according to data he sent me.

I've tried with more than enough fuel but on the street its so much smoke you can be arrested. With the smaller unit is almost smokeless and much better boost.
Smoke on the CR is not accepted.

You don't have to be smokey to make nice numbers.
This 49/51 wheel has caused plenty pain for myself too, but if you get it right it can perform well. Can make 2bar @ 2.5k on a 3.0tdi (with usable street lambda).
Hybrid are like a lottery..too much guess work
Bigger frame units are better in that sense especially if you want big power but they are not pnp.

Believe it or not i can burn 130mg of fuel with a smaller turbo without issues and without smoke and its lovely to drive.
This turbo i built myself for the first time and its doing better than everything i ever bought so far. MrChill here know the story
My problems right now are of different matter, called EOI. On the street you can not see what works and what doesnt. Time for dyno.

May I ask you which turbo brings 46/50 and from which car is it? does it have the new generation blades lighter?
