7mgte ticking noise

[Joe1234]

Hi everyone, I'm new to this forum and I'm hoping you guys can help me out on this one. I have a 89 supra turbo. Although the engine has 189000 miles on it, it's been running great and strong. Recently, the engine developed some kind of ticking sound. It really sounds like it's cominf from the turboitself but I'm not exactly sure. Maybe it's a faulty turbo? The car makes no noise when idling. Everything sounds perfectly normal. The car is pretty much stock besides the k&n air filter and blitz nur spec exhaust. While driving normally(between 1000-2000rpm) there is a ticking noise. As the Rpms increase, the ticking noise gets louder and gets faster. When idling there is no ticking at all. I have no idea, I'm stumped lol can u guys please help? Thanks
