I understand that it matters about the hp not the psi...but like if you want to hit the 280whp range with a small turbo.. lets say at 18psi on a bone stock..i mean stock everthing...will it be ok with 18psi or get a big turbo and push only 10psi and your at the same hp range...............

First you have to be more specific about bone stock ,bone stock what motor gsr,type r ,L.S B16a2,B20,k20 what . second before you make a horse power goal do a compression and leak down test to make sure that all of your cylinders are good,then look at what turbo setup you are going to run with not just what size turbo include what type of engine manage ment you are going to be running with aem,hondata,crome,neptune etc. Also dont forget what type of fuel management meaning fuel pump injectors etc , I forgot to put are you going to to a full kit or a custom meaning that you will piece it up yourself.

But power all depends on who tunes it the condition your engine is in at the time and your entire setup .
