View Full Version : Metric Size of Oil Return on SR20 Block

10-26-2005, 07:36 PM
I'm looking into buying the -10 AN Oil Drain Adapter from Phase2motortrend.com for my s15 Spec R T28. If I do this, I'm going to make the stainless line to go with it and do it right. My question is, what size thread is on the Block of the SR20DET for the oil return tube for the turbo? I'm going to buy an adapter (metric to AN) to put in the block and I'll attach my line with an AN fitting. Anyone know?
