Turbo help needed
Tap into the oil system and run a feed line to each turbo. Just make sure both turbos are above the oil pan so you have proper drain back. If not you'll have to run a pump to get oil from the turbos to the pan.
462 ci, go bigger on the turbo's
At least buy halfway decent turbochargers. I know there is nothing better than dressing up an ancient all iron motor with ancient technology turbochargers to some people, but why not make use of those 462 inches?
As for the oiling, I'd use the engine system. Otherwise you'd need to add tanks, pumps, and God knows what else. Just upgrade your oil pump, add at least a quart of pan capacity, and that should be more than sufficient for a high RPM, TT V8.
