Turbo Whistle at high revs

Hey Guys,
My S15 has started to make a high pitched whistle at high revs. Its coming from the turbo and I'm getting slightly worried. I have an Apexi power intake and its still boosting 8 on te factory guage.
Any ideas please?

Could be a leak from the manifold to turbo gasket, they can make a varity of noises!

Craig i was going to metion concepta tunning they are an awesome company!!! i needed gaskets before a drift day i orderens one day before and they sent them special delivery to me!! and with some haribo :D:D:D:D

Malta definatly get high temperature lock nuts, I have special helicoil inserted nuts on mine that i stole from work they are amazing and dont allow themselfs to rattle lose.

Make sure it is your turbo gasket first though. It could be a leak and what sort of whistle noise is it?? since i have a power intake on mine and you hear loads of turbo spool?

Yeah I get a bit of whistling if I start boosting but you can only hear this from around 2k to 3k revs then the exhaust note takes over :wack:


Tooley - I ordered my elbow to downpipe gaskets from Conceptua... dealt with a chap called Chris. Very helpful and quick delivery as you say!! :thumbs:

I got a Haribo too! Hopefully the gasket will last a bit longer than the Haribo did! :)
