K03 is blown, buying k04, but which one?

[Grangalan]

Well my turbo is giving me the death whine so im looking to upgrade. Since im AWM im going Hammer. I am talking to my turbo distributor and he needs to know exactly what i want. I know its k04-15 but aside from that does he need to know anything else aside from that?

I know there are so many options k04 wise and i cant afford downtime due to wrong turbo. Any insights?

install kit (gaskets, washers, exhaust mani bolts) and thats all you "need". when i did mine i put on an 034 hi flow mani and a hfc, moved my powerband to ~3800 and pulls much longer than stock exhaust mani

edit: but i am at full boost b4 i hit the powerband

people been making moves on the k04-023, but if your gonna drop that chedda you might as well get a gtrs

what car does the K04-23 Come in?
what supporting mods would be needed to fit it on a B5 A4?
is there a significant power difference from the K03s?

thank you

mjmturbos sells a direct bolt on variant, but its mad loot, the audi TT225 however comes with the k04-020 or k04-023 depending on model year. powerfigures in the 280hp range are not unheard of.
