ok, ive just noticed a sort of high pitched squeel when the turbo starts to kick in, so im guessing i have a boost leak somewhere?
i couldnt check right now because of lack of light, but are there any air pipes that a prone to splitting that i should check first?
also, whats an easy way if checking the pipes? just leave engine running and feel around the pipes? because you only here the noise whilst the turbo spins??
turbo is a vxr on a z20let fitted around 6 months ago.
thanks for any help or advice, chris
