I'm guessing that oil pressure builds as the engine revs higher(correct me if I'm wrong) so what's the PEAK pressure that will be present inside of the oil feed line on a D-series(d15b2) engine?

Also, what is the typical heat heat of the oil in a running d15b2?

And the temperature range CONDUCTED by the exhaust manifold, i know the exhaust gases can get pretty damn hot, but what's a guess at the actual heat of the manifold itself?

 

dont quote me, but i believe oil psi can get up to 70, so you want to test and restrict it if need be. oil 175-250F? manifold 350-500F?

 

Good question! Any know the specs for a B16?

 

I believe the max pressure that you want your turbo to see is 60 psi at max. I would do like 30-40 for an average.

 

my turbo sees 85psi almost regularly.
which is probably why she's smoking again

time to tighten the needle valve down again
