Default changing K03 with K04s Q's

I'm new to this Audi Forum, And not very mechanically with cars, I have stock 2001 S4, getting a Giac chip installed next week, Guy in my city is selling his K04 turbos of his S4,(working good), Thinking off buying them, but need more info, Can i just change my K03 with his K04 turbos? ,Will the car run like its supposed too or do i need to do more mods to my the K04s run properly ?What else do i need ?Thanks

Default you at least need inlet pipes. without fueling/programming, you're leaving performance on the table

but you can run with stock fueling and the GIAC chip. AKA Stage 3-

Default

Not a great idea putting used turbos in a car. If he has the k04's then he has the inlets too.

Default Indeed. Especially when you consider that the engine needs to be pulled to install 'em.

Might as well save up a little more and get a new set.

Default or just engines. it will be the less work, probably

you gotta take them both out anyways, instead of taking everything apart, just swap'em

Default Most likely you aren't saving that much. There is a new set of k04's.....

in the classifieds for less than 1800.

Maybe you will be be lucky and will have no problems. But you drive a s4 so always be a pessimist.
