[papie]

hey guys i have a dc2 i have rebuilt the engin and still running it in. i have put
a 68mm holley throttle body on and it whistles from 2500 to 3500 rpm then stops. it only duz it in that rev range it sounds good when u give it a quick rev but gets anoying when your cruzing cause it will keep whistling if u stay in between that rev range and its loud. why duz it do this??

Sure its your throttle body?

It could be your throttle body, intake manifold or exhaust manifold gaskets.

might be a leak in the throttle body? check for any air leaks, also might be an air leak in one of the pipes? check out for any air leaks.

Was abt to post up a thread abt this, i wanted to get the soudn aswel, until i read the replies, guess its bad then, ever since i got rid of my EG Hatch the new owner of the civic started to get the noise.
I thought it was kool.

how do u check for air leaks?
get a small garden hose, put one side near ur ear and the other side to where u think there r any air leaks. u will b able to hear it and u will know where the leak is located if u got a leak.

i think its the air filter and the sound of it is cool.

I just fitted an Apexi Power Intake into my stock airbox and I'm getting a high pitch whistle when I'm on the throttle too

just remember guys your car is taking much more air than it used to, it could be as simple as the air being sucked through your pipe!

[papie]

i have pulled off the pipe and air filter and it still makes the noise.

its prob just ure bigger IM and ure intake - fully sik JDM yo!

Just taking airbox cover off gives a slight whistle at idle.
