Adding a TURBO
Adding a turbo to a Detroit 8V71, 318 HP will up it to 350 HP. That was a factory option for 8V71 Detroits. It has been about 35 years since I converted one to a 350 HP but the first thing necessary will be to buy the turbo, exhaust manifold and cross over pipe. I think that you will only need one exhast manifold. You will also need to check the build sheet for your motor. It is an aluminium tag on the valve cover and it will tell you what injectors and cam timeing your motor has. If the aluminium tag is missing you can pull the valve cover and look at the side if the injector for the ID#. Determining the cam timeing is much harder without the aluminium tag. You would need to pull the transmission, clutch, flywheel and bellhousing to physically look at the timeing gears behind the bellhousing. If I rember correctly there are three settings, retarded timeing, standard timeing and advanced timeing. I think large injectors and advanced timeing was used with the turbo to get 350HP.
Good luck, a DD 8V71 is like a 283 Chevy or a flathead V8 Fo#* they will run forever.
