Re: anyone Turbo'd a 258 or know about someone who has?
 

I would not even consider any kit that did not have a turbo with a
liquid cooled center turbo bearing assembly. The more you fabricate
yourself, of course, the less expensive it is. Can you bend pipe and
weld?

All turbos are engine oil cooled, this one we can see at least 3/8"
Recalculating lines: http://www.pbase.com/740atl/image/48271546 Trouble
is oil burns at five hundred degrees in an exhaust temperature of two
thousand. So must idea it down for whatever the owner's manual says to
know the next time we start it, it's bearings won't be siting in dry
charcoal.

The turbo bearings are directly lubricated and cooled by engine oil,
except on very large turbos which have their own independent oil
supply. However the center assembly or "cartridge" on some also have
passages for engine coolant. This keeps the cartridge temps lower and
means that the turbo is less vulnerable to coking if engine stoppage in
the high heat condition occurs. Mopar-specifically one of the guys
formerly under Huebner on the turbine project, maybe Steichen(??)-came
up with the idea and Chrysler/DCX held a patent on it for years.

High dollar turbo engines may also have pre-oiler electric oil pumps
installed so the turbo can receive oil flow before and after engine run.

I know you've never see one, so I Googled a stock LS1 Corvette with
twin turbos just for you, something may click in your head, seeing most
of the plumbing is in view:

them in their small engines since this '61 Corvair:
