B16A turbo with stock internal and about 6-7 boost

does anybody know how long will the turbo last (no redline or all out racing) and how often do you have to mantain it??

or it's better just to fully built the motor then turbo it.

 

its not a question on how long the turbo will last, but how long will the motor last before poping, no you dont need a rebuilt motor for 6-7 pounds, once you want to go higher then that you will first need a standalone fuel managment, then you will need to build the engine.
