      Hey, I'm just curious as to what upgrades are possible for the k04 turbo without going bigger. Cause I've pretty much exhausted the minor preformance upgrades I can do. For example, I have a short ram intake, forgo turbo inlet pipe, forge spiltter vavle, 42 dd turbo back exhaust and a 4 bar fpr. I have seen stage III+ turbo kits from apr for the 180 hp tt's. So pretty much I wanna know if there is stuff like that for the k04, and where is there a good site to get it from.
      It would be greatly appreciated since I recently over the past 2 years fell in love with my tt and want her to be getting more to the wheels.

      Easy question to ask, but very difficult to answer. Expectations for an average install and tune sould be around 280 to 300 whp. Some exceptional people are pushing upwards of 330 whp. Upper end? No one knows yet, still testing its limits.

      It's up in rod territory...

      Also if you want the most power add water/meth injection to your list of required mods.

      Add another 15% to the whp to get a reasonable estimate.

      here is how 22psi on the F23 comes on. Need to get a MBC from what I have been experiencing the F23 will hold 26psi to redline.

      I go for max ramp as I have rods so IDGAF if it spikes

      Somwith supporting mods, largeport head, tubular manifold, 80mm intake etc, would 350bhp at the flywheel be reachable?

      Well given that Atomic said 300hp at the wheels, add 15% to that and that gives you 45. So yes 350 at the flywheel should be possible.

      Add rods, software, injectors, and an efficient intercooler to your list. Might be able to get by without water/meth injection, but be prepared to add it on. Large port head not really needed. Clutch may be needed soon also.

      Getting expensive, isn't it?

      Honestly, if you set your goals somewhat lower (say 275-280whp), the basic F23 kit with a box tune and new injectors will be a hoot to drive. The F23 brings the torque on quick, so rods would still be advised or have the tuner turn down the boost/torque request.

      I'm pretty sure you're not anywhere near exhausting the minor performance upgrades available to you. A hybrid turbo, (Franken Turbo F23 preferably) is your best bet at reaching your power goals... and even with that you'd still need to optimize pretty much everything else around it to get there.

      True.

      The numbers I threw up were fwhp numbers, so 15% is a good wag. I use 22% for awd conversions after seeing some actual from the engine stand to the TT dyno comparison somewhere.

      I'm still getting my f23 dialed, but it's starting to feel really good. Once I cross the last items off my list (injectors, pump, tune) I'll be ready to push the envelope a little. But even on my APR tune this thing is nice.
