notice I said drill for oil, and use GMC rods, of course you would use insert bearings. You wouldn't use a stock 216 oil pump, you would use a GMC oil pump. There would be very little stock for that matter. I'm not sure of the current state of development of turbos, but I don't think they use ball bearings any more. The fella at Ross pistons said that turbocharging inline 6's are actually pretty popular due to the fact that the breathing of the heads on most inlines quite frankly sucks. You don't just throw a turbo on pretty much any engine without a fair amount of modification. This is one of my really favorite things to think about, after the 12 port of course.
