using a socket with short extension then a uni joint then several more extensions to bring the ratchet to the front of the plenum makes it quite a lot simpler on my rb20 may help with your 26
i had the same thing under boost
tuned out to the the turbo exhaust flange nuts comming loose have to tighten them up every 2 years - tabs to hold the nuts in position are useless
only when boosting under load - at idle didnt do it
got pregressivly worse over a week or 2 while trying to work out what it was.
also check exhaust manifold bolts to the head - may have broken a stud
