to many veribles to comment. Every dyno is differant, every engine is differant etc etc. Find K20's running simular mods and compare to them. But for intake, catback and a VAFC on a JDM K20 you would expect around 125ish kw at a guess.

But at the end of the day a dyno should only be used as a tuning device.
