RS4 B5 JHM RS6-RS

B6/7 S4/RS4
#1

Good morning gents,

writing this on behalf of a good friend of mine who owns a RS4 B5 avant and he wants to upgrade his turbochargers. We are positively biased towards JHM RS6-RS turbos so my questions if you know are:

  1. does he need upgraded injectors?
  2. What is the normal operational pressure and what are the overboost levels?
  3. is there a separate tune from JHM on these turbos?
  4. any other adjustments that need to be made to install them safely on the RS4?

thank you!
