Recently picked up another engine for my New Yorker. The engine in the car runs ok, but it's got 150,000 miles on it, so I would like to redo this other engine over the winter. What I'm looking for is info on making sure it's reliable. A little extra hp would be a bonus. I haven't torn into the engine yet, but I got it from a friend, that said it ran before he parted out the NYr it was in. It was suggested that I should do a turbo 2 upgrade, but not sure what that entails or where to get the parts. Any info about block, head prep and what to look for upon disassembly, would be greatly appreciated.
