damaged blades on OEM K04 - sensible replacement?

[GT4094R]

Hellow, this is my 1st post here.I own avus rs4 b5 with 3" exhaust, walboro pump + bigger injectors and W/M injection.Remap was done before all that mods.So I have to plan to remap it again..

Few weeks ago my turbos sucked something inside and started to whiste.With camera inspection we saw that there are few blades on each turbo little damaged.

Now I can't decide what to do.I use car as a 2nd car and love response of OEM turbos.
Is it worth to do some cheap mods on cold side?
My friend gave me for free, new CW 2275 from RS6 turbos...Is it worth to change?Benefits?Gain at top end?
What about 2277 wheel out of the 997 turbo or 2080 wheel with 3mm larger inducer and same as oem (51mm exducer) is it worth for such a small difference?

I just want to know how much I am going to loose with spool and what benefit should i expect at top end?
....or is better to replace them with OEM ones?



Thank you!

The 2275 wheel from an rs6 k04 is meh. The 2277 or 2280 wheel is what everyone is using in everything these days. U give up around 500rpm of spool but pick up a lot more mid and top end

Easiest thing is to just stick with the stock k04 wheel as it spoils fastest

Get a brand new CHRA's

why not upgrade to rs6 chra, isn't it a direct bolt in?

rs6 chra is a direct bolt in into a ... rs6

a 2275 rs6 wheel will not fit into the 2081 wheeled rs4 k04 without compressor housing machining. the backplate is also different size
