just noticed some wierd clicking noise coming from exhaust mani/turbo ???

[91nissantwo40sx]

ok i have an SR20DET stock boost running with a 3" pipe with a high flow cat converter and a resonator.

I just noticed this after i had shut off the car i started hearing a clicking noise from the exhaust manifold or somewhere around the turbo. The noise continuous and its slow like every half a second. I am thinking it is the turbo still spinning and hitting something? i dont know if this is normal and any help is appreciated!!

Sounds like the old girls just cooling down. How loud are the clicks?

change your turbo fluid.

Hey I dont think it has anything to do with your turbo. I am still n/a and have the same clicking noise coming from right around my header after the car is shut off, cant really figure it out either?

most likely the engine/exhaust cooling down. The thermal expansion isn't uniform through the engine and exhaust piping so that's just what it does.

my ka makes popping/snapping noises for about 10 minutes if i drive it REALLY hard then come home and shut it off.

haha yeah it has to just be cooling off. mine does it for 30 minutes. depends on how hard you drive i guess.

considering the turbine housing of the turbo can reach the thousand degree range...yeah...Clicking is not a big deal
