Yea depending how hard you're going to push it especially a turbo you have to upgrade some things when you start pushing PSI to the limits. An absolute mod right off the bat even staying stock you need new injectors, from there on can really start denting the wallet as if the turbo wouldn't be enough to dent it lol
Things like o-rings, rods, cams , valves etc and so on.. In the same token even staying stock will put stress on all those things and more and cooling becomes a concern as well not just for the engine but the turbo itself.
