K03/k04 Turbo Specs?

Hi guys just wondering if anyone has had any experience with these turbos (audi/VW 1.8ltr motors).

I'm doing some hunting on the webs and I'm finding conflicting information but mostly positive feedback.

My application is twincharging the 4k, running ~6psi (yet to be confirmed) on the charger and letting the turbo add another 7ish psi on top of that.

Both units will be in circuit for 100% of the performance ergo no bypass valves.

I've heard only a little about the K03, the K04 is sort of the direction I am looking at because of it's supposedly quick spool time.

 

The main reason I am looking at this turbo is because I can get them new and I can get them cheap from a friend who imports them.

I also have access to free RB 25 turbos (used, need rebuild), are they any good for a 4k?
