what d-series setup? health of the motor? desire of longevity, etc.

100whp over stock (stock internals) if you think you want it to last (200-210 or less depending on model), more if you don't care. i've made 206whp on my d16y7 using a 13t (tiny a$$ turbo from wrx and junkyard kit). i'm not out to make mine fail, but if it does no biggie...it'll just force me to put together the one i've been sitting on for over a year.

d-series rods are pencil thin and pretty weak. think about your goals and desires with d-series.
