The stock bottom end will be okay, but you might need some stiffer valve springs with over 12 pounds of boost.

I doubt that's a dc5 k20a engine. More like a lower compression a2 lump. I doubt a dc5 would run that much boost without any issues. I'm quite sure Paul from tdi advises a built engine from power above the 370/380 mark. At the end of the day I'm sure there's people out there that might have got away with higher pressures but I know from experience that it's a recipe for disasterpulpmelon_r said:Ben @ TDI-N runs 18 pounds of boost, stock motor K-swapped EG
Tune it right and it all stays together oddly enough.
