This is an upgrade turbine wheel for the 2260vk units (audi and bmw).
I would not use 0.460um nozzles for normal city driving situations.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?
Maybe good for better transient response, but building inertia of larger wheels is still a problem. Low-rpm response is not great and requesting boost early only causes surge & shortens turbo life. I am running a 6+6 hybrid variant now and low-end response is not good, even with massive fueling.how about Gtb2265Vklr with ceramic ball bearings, and new generation of wheels ?
If the goal is 250+, it's still better to go with larger turbo and have reasonable boost request for shaft speeds that keep it together. Smaller wheels and A/R fix the low-end, but don't expect it to last long requesting high boost if you want big numbers. Really depends what you goal is and how reliable you want this to beA huge turbo is overkill and useless if you plan on having 250hp.
I am discovering lately that small turbo can deliver plenty of air, enough to burn smokeless lots of fuel.
Have you considered upgrading to a GTD2060VZK or better yet AVD posted on Facebook that they created a GTD2265VZK with an upgraded turbine wheel and a gen II compressor wheel.I got more than 250hp so that is out of question, with gtb2260vk, I know that gtb2260vklr will spool better then gtb2260vk, and will give me more on the top end.
