Toyota Supra MK3 Turbo (7M-GTE)
 

I have a Toyota Supra MK3 and recently i realized its hard to get the turbo gauge go up, it goes randomly up but not full i know if full somethings going to blow. Still a noob, and im like 17, so basically im asking is all about the turbo. At times i feel the kick in the highway, but is there i way i can "activate" the turbo quicker? Even going at 80, and 90 i cant feel it. =(

Before trying to get it to spool quicker (which is what I think you're asking), I'd make sure there's not an underlying issue. You say the gauge is hard to move, and somewhat irregular? Install an aftermarket boost gauge to verify yours works properly. Also make sure you don't have ANY vacuum leaks, because they will cause your turbo to work harder and still leave you with less power
