back on topic,
from what i gather all you need to do to uprate the internals on the k04s seems to be the rods, as the pistons can handle the extra power.
what about the k03 engine.
ive squared away a k04 turbo now, so the conversion is on the cards, id also like to get water methanol, and i like the idea of the scrick cams. that could potentialy put my BWA engine above the 350hp mark if not even more.
if i was to uprate my internals would i only need the rods to reduce the likely hood of bending things or would the pistons or anything else need doing?
