Howler Stock VGT Turbo Kit Dodge 5.9L Cummins 2003-2007

Massive improvement to engine performance.

My 2006 dodge ram 5.9l cummins has about 325,000 miles on it and all stock. I have been slowly fixing some of the issues with the cummins engine, and it was time to move to the turbocharger. But I also wanted an engine brake to keep from going through brake pads on mountains. This is the only package with all in one. The turbo spools up quicker, and now there isn't any black smoke at acceleration. All of the parts are high quality. At startup it sounds like a jet engine when it's cold (with the engine brake switch on). The engine brake does a great job and slows down to about 45 mph. One thing I wish the kit had included was the turbocharger supply line (I would have paid more to have this included). Mine snapped. Everything worked at startup and is still working great. Installation instructions are very detailed, and I would highly suggest printing them in color. Here are some hints for installation: -Drain the coolant first! Instructions don't mention this at the beginning. -If your engine has miles like mine, then you know original parts seize/break when removing. Make sure you have an easy out before you start. The allen keyed engine plug that you remove for the engine coolant connection rounded out on me. I had to drill it out and use an easy out. Use grease on the drill bit tip to minimize metal shavings from entering the engine (remove grease and shavings often). -Do not hook up the exhaust pipe or elbow/adapter until the exhaust header is bolted up and the turbocharger is bolted to the exhaust header. -I have an automatic transmission and a 5 inch exhaust. I had to loosen the exhaust clamps and modify the exhaust hanger mount to the transmission bellhousing in order to line up with the turbo. -You're going to need crows foot wrenches/sockets to torque the turbo mounting nuts. -It took me a while to get the turbo oil drain line bolted to the turbo because of the engine mount. One bolt can be installed from the rear side of the engine mount, and the other from the front of the engine mount. I am still getting used to turbo. But the engine warms up quicker, the turbo spools up faster, plenty of air is supplied for complete combustion at all loads, and the exhaust brake works great. The exhaust brake is pretty loud and sounds like fireworks as the turbo winds down. I would highly recommend this package for an upgrade that doesn't require any tuning. I had a blast testing the acceleration and exhaust brake for a day (I had to verify everything works!). My next step is to purchase +60 horsepower injectors. Thanks BD Diesel for the high quality turbo upgrade and great instructions!

This is a must do… was blown away with the increase in power and exhaust brake is amazing. Wish I would have done this mod sooner!

Great pros. Some cons

First of all this has been the best thing I have done to my 06. Response and power are much better and towing is great. I really do love how much this turbo has done for my truck. Something I was not happy about was before I purchased I was told by a BD salesperson this kit would be great for a bone stock truck, not the case at all. Stock truck does not give enough fuel to spool this thing and when it finally does it makes to much boost and the truck throws an overboost code, that code cuts fuel then that throws an underboost code and your in limp mode pretty much. Was pretty disappointed. Then I called BD tech support and that person was mad I was told it would work on a stock truck. Either way got a programmer and all that is solved. Truck runs great. The only big down side is you lose cruise control essentially. The turbo veins use the throttle position to figure out where they need to be, when you set the cruise the turbo sees no throttle input and the turbo opens up and the truck has a hard time spooling so then exhaust temps rise, especially in the mountains. Not a big problem in the flat lands running empty, but with a load or even in the mountains empty cruise control is gone. Just be aware of those things and you will not regret this kit.
