Hi Chris 28, Buzz here. Among other things at work i teach an ETOPS class for other mechanics.
How can a "Thunder Guppy" become ETOPS? well, first you fly it more than an hour from any airport you can land at. According to the FAR's you're in ETOPS territory then.
Besides, how could they get 737's out to the Islands unless they had the range? UAL's original batch of 737's would only carry a few hours of fuel, small center bladder tank (or 2 ). Later they made the center tank integral which tripled it's fuel capacity. I hear rumor of a cargo pit fuel tank also, we had some 727's with them installed.
But you have do carry more than just extra fuel and a couple more radios. You have to have your maintenance program set up to track the oil consumption, and have a way to prevent easy mistakes from causing in flight emergencies. And then there are critical systems that get different treatment after you fix them.
Most of our ETOPS diversions are coused by sick passengers. Maybe we should give them a once-over inspection before they get to fly? (grin)

Aloha flies the 737-200 ETOPS from Honolulu to Christmas Island, Johnston, Midway, and other islands in the mid Pacific. Aloha flies 737-700s across the eastern Pacific from HNL, OGG, KOA to LAS, OAK, & SNA.

Just as a side note: only the latest generation 737s (600-900 series) have the range the travel from the mainland to Hawaii with the use of only it's own fuel cells. The older aircraft are inter-island aircraft which are sometimes ETOPS capable, but still have a range too short. These aircraft get to Hawaii by use of temporary fuel cells which are anchored into the passenger cabin and plumbed into the Center Fuel Tank. The aircraft is operated on a ferry permit and is not allowed to carry revenue pax. There is a great article about this sort of operation in the latest "Airways" magazine which is interesting. The particular article is referencing Hawaiian 717's, but the concept is the same.
