fwiw
for an oil pump use a belt driven p/s pump off a small car, they are compact and can move sufficient
oil at and easy 40psi or so to feed a turbo, as for safety T in a pressure switch to deactivate the fuel rack
solenoid and kill the engine should the belt break and pressure be lost.
as Shipchief stated, you better do away with the oem big end grooved brgs, or they will go away for you.
i would set a limit to about 5psi, with the stock pistons, maybe 7 psi, and use a radiator neck and caps for pressure
regulation, 7lb caps are common, as are 10 lbs, 14, 15 and 16lb caps as you get some experience.
you can use a heater core for an intercooler, or better yet an old GM evaporator, they are very strong, aluminum
and readily available and can take the pressure.
it might be fun, but likely not at all practical for output over about 20kwatts electrical in my opinion.
oh ya,, before i forget,, i sure would want all my failsafe shutdowns fully functional, and damn sure my governor
working in a first world manner.
somehow a big twin turning 2 grand with 30psi of boost seems pretty dangerous to me.
just be sure to get it all in a utube clip, especially the 2 grand 30psi run
