> what do you mean by 18-19psi being hard on the motor with that turbo? whats the difference in the same psi with a different turbo? just confused about what you are saying.

A smaller turbo is harder on a motor then a bigger turbo at the same power level. lets say @15psi on the 2871 you make 300 whp. and sc61 @ 10psi you make 300whp…  
  
get it?

psi is psi, its cfms or lbs/min that change the amount of air injested.

woundnt a larger turbo running equal psi push more air (aka more cfms) since the turbo is larger (hence raising the sq inch part of the equation).
