I know the turbos from the early Cummins diesels put into Dodge trucks are good for small engines. On the Cummins they were to small and they ran them at 110% all the time to get any power out of the engines. Needless to say guys that owned the Cummins ripped them off and put on bigger units. I would call Margarete at Diamond Diesel to ask her what turbos they were. She can tell you the hole story behind them. She will know more about turbos and injectors they any person you will meat on any board. It's all she has done for the past 30 years. She knows her shit when it comes to turbos. She can recommend a turbo of the correct size for you.
