[s-cars] Turbo Oil and Coolant Line Specs for Garett K26/T04E

[Theodore Chen]

consider combining the NPT to AN adapters with the AN hose ends.

earl's sells NPT hose ends that will attach directly to AN hose, so you
can eliminate a connection (which saves money and reduces the number
of failure points).

also, 6AN seems a little small for the oil feed line, but i suppose
the turbo doesn't take much oil.  but why is the oil drain line so
big?  is there oil from somewhere else going in there, too?

i agree - it's worth it to use braided stainless steel hose.  it's
dirt cheap compared to the cost of repairing your engine if the
hoses blow (which is a distinct possibility with rubber hoses).
