hey guys i know it’s probably a stupid question but i recently got a new turbo and just wanted to know how bad for my car it would be if i drive it with everything else stock in the car aside from a front mount intercooler i have a 1998 r34 gtt and i am putting a Kinugawa Turbo 3" Anti Surge TD06SL2-20G for Nissan Skyline
just wondering and hoping someone would know how much more i’m gonna need to upgrade
