I have seen more talk about turbos on 6.2's than I have heard in a long time. I am glad to know that so many peolpe on this page have diesels. As I looked at more power from a turbo from my 6.2 I found some problems. I decided to leave it stock. It save me money too be it is fun to talk about all the power you could have. I lived near a man who has set the speed record on the bonneville salt flats in Utah. He also built some of the first turbos of the 6.2. The dealers had him install his turbo on their new trucks. He explained that one of the reasons he stopped installing the turbos on the 6.2 is because the right rear cylinder would burn. The cylinder burned because the 6.2 does not have oil cooled pistons like the 6.5 has. Instreastingly enough, I have talked to two men personally that said the same cylinder (right rear) is the one they had problems with on their 6.5. If it will burn on a 6.5 it will probably burn faster on the 6.2. I don't pull alot either so I enjoy mine the way it is. It runs well, and worlds better, now that I am at sea-level compared to 4500 feet. During the move east, I pulled a car behind me climbing up to 11,100 feet over the Eisenhower Pass on I-70 just west of Denver. Then I wish I had a turbo. I understand that the propane (which can only be run with a turbo) has a soothing effect on the engine. It should increase your ecomony 35% to 45%, and your over-all mileage (figuring in the cost of propane) 15% to 20%. One other option would be to replace the timing chain with a gear set. The timing can fluxcuate 7 to 8 degrees on a tight chain (one that is not worn out). With the fuel injection pump being a very very presice piece of equipment 7 to 8 degrees is a lot. The timing gear set will reduce that number to 2 or 3 degrees. You can also try turning up the fuel and advancing the injection pump alittle. My diesel has been good to me also. It is not the fastest unit on the road and not the most powerful one either but it can run unside down, requires little maintainance, and once it is started it probably won't die on you.
