The S13 SR20 red top oil pickups have no support bracket on the strainer itself - only on the tube. While the S13/S14/S15 blacktop SR20's have a support bracket brazed on to the strainer . So I went and got the updated oil pickup from blacktop models.
It bolts straight up with no modifications required. However you need to get the oil pickup gasket as the updated version uses a metal gasket instead of the O-ring of the redtop pickup - the updated version is a much more reliable set up. I will now monitor for any change in oil pressure characteristics.
Update: Oil pressure now seems to build up a lot quicker on start-up than before. Also pressures seem to be a little more stable. Great outcome from a $50 part! Crucial!
