hey guys i just fitted and t28 to my sr20 when i first installed it would like boost but was lazy and my adjustable boost controller wouldnt work it was 15psi no matter what id did , occasionally it would make a popping noise and i would loose boost , but now i have no boost at all ive checked all lines and turbo is stll spinning but will not spool im a newb anyone possibly point me where i have gone wrong :S

you sir more than likely have a boost leak. Please stop driving the car and find it. if not , you are over working your turbo and soon will destroy it.

get a friend to accelarate the car see if you're blowing air by the manifold could be that it is not tight enough and the air is escaping through there. That happpened to my brothers car.

check every single cupler connector clamp everything more then likely u have a ripped cupler and just cant see the rip or maybe u blew off the charge pipe or something and also where did u hook up your wastegate line to
