Wondering if anyone has successfully added a NOS kit to an Audi FSI car (preferably non-FI).
I know that JHM has the kit for the B6/B7 S4, but that one won’t work on the FSI engines.
I am interested in a possible application for the 5.2 S6 engine, but figured there would be more chance of a response from someone in this section possibly adding it to their RS4.
Z06psi suggested a dual 25 dry shot to each of the dual airboxes on the S6. Somehow, I don’t think it would be quite that simple, but I have no experience with NOS kits. I would guess that there would have to be modifications made to the fuel injectors, plugs, dual ECU tunes (yes, the car has two ECUs), and probably other stuff, but would like to hear from any experts what they think would have to be considered to add a 25 or 50 shot to each side.
Would an aftermarket controller be necessary, or would the ECUs handle everything. I am looking for something completely safe that will work with the other bolt-on mods I am having done.
