Hi, I have a 1991 Honda Integra (3 door DA-5 - 120kms) that has this amazing (annoying) squealing/whining sound when accelerating.
Details: The sound is coming from the Intake Manifold / Throttle Body area. When I removed the Air box and arm the noise is very loud. The noise only happens when I exceed approximately 2500rpm and its only when its under load i.e when I??

Get your nana out of the passenger seat and try listening for the sound again

Is it squealing or whining!
Whining could well be just a simple vibration around the intake at the bumper end of the assembly. Try adjusting / tightening retaining bolts and screws.
Or just stick a JacksonRacing sticker on your bonnet and tell people its meant to sound like that.

Yeah I could take a closer look for a vac leak - I guess I discounted that idea when I found that it didnt make the noise when revving in neutral.

get some carb clean or anything like that and spray round your manifold. It will tell you if there are any cracks or anything there. Check your pcv valve. If its not working the noise could be coming from there. While your there clean out your manifold with some subaru throttle body clean. Great stuff. Could be a whole lot of gunge build up.
