Hi guys, I spent a few hours tonight constructing some
ss-braided
feed
and
drain
lines for the mock-up of this Borg Warner TO4 turbocharger. The
oil
feed
line is
a -4AN setup including a metric to AN adaptor (M12x1.50 to -4AN)
that
threads
into the front end plate of the engine where the old turbo oil
feed
banjo
fitting goes.
The oil drain line is a -12AN setup (yes, very large) with a
pair of
1/2"NPT
to -12AN
adaptors threadded into a pair of machined aluminum turbo drain
flanges
available
on eBay (Vecco Performance I believe machines these).
The exhaust manifold being used is the HKS undivided cast iron
manifold
for
T4-style
turbochargers. Price is about $250. Although I don't believe
that
particular manifold
is the best choice for you airborne guys, the pictures should be
able to
display enough
of what it takes to mount the turbocharger to the 13B as well as
give
you a
rough idea
of its size with respect to the engine, what kind of room is
needed,
how
the
lines are
built, etc.

Be careful replacing that turbo oil pressure feed plumbing with
aluminum
Brian.
Aluminum softens at high temps. It loses half it strength at 500 F.
What does the BW TO4 weigh?
What does the HKS manifold weigh?

Hi Paul,
If we're running oil in excess of 500 degrees in our engines, then we've
got
something much more wrong than the fittings we're using. :)
I've never seen any problems with using these fittings. They all seem
to
work
just fine, but if any of you guys want to use something of higher
strength,
Earl's
and Aeroquip (and the like) make fittings made out of stainless steel I
believe.
They're more pricey but I suppose they'd be higher quality. The
candidates
I
would see for using the steel over the AL fittings would be the adaptor
for
the engine block, the adaptor for the oil feed portion of the
turbocharger,
and
perhaps the adaptor for the oil drain line on the bottom of the turbo.

It is the bearing housing that can run 500 F. After all it is in intimate
contact with the 1400 F turbine scroll. Might work in a car where the
turbo
is loafing 99% of the time. The drain back is less critical. As it will
take
more time to dump all the oil over board if it fails.
Never the less here is a picture of the heat shield Mazda thought
necessary on
the 89-91 second gen turbo drain back.

Hi Paul,
Thanks for the tip. I've updated my document file to accomodate this.
Here's a link
to the 1/8"NPT and 1/4"NPT to -4AN steel adaptor fittings to replace the
aluminum
ones:
