S13 blacktop freshly rebuilt 200 miles on it, I was driving the other day turning up the boost a bit and all of a sudden it started acting like it had a boost like, Went home and noticed it was making a very loud tick/Knock noise, I pulled the motor and checked the bottom end, Everything looked good, Nothing wrong with it, Threw it back in, I have good oil pressure and 150psi or above across all cylinders, Noise does not go away when unplugging coilpacks or injectors. Does not make noise while cranking. So far I have checked timing, rebled lfters, Changed spark plugs, Made sure all my shims were still in place as well as rocker arms. I cannot figure this issue out, Does anybody have ideas on what to check? Bad lifters maybe? I'm really scratching my head at this one. Noise increases with RPMS. Thanks!
