Industrial Injection is now offering a new turbo. It is very similar to a Silver 62 but it is not polished and does not have the Silver Bullet upgrades. It does come with the larger S330 frame which has the wider heavier duty bearings. It comes only in a 3rd gen. configuration and is a drop in replacment for the factory turbo. It would be a perfect towing turbo and would also add enough air for some racing as well. (Performance Towing) They are genuine Borg Warner turbos. They are NOT Chinese knockoffs. They are a high quality turbo that will last you a very long time.
The Thunder 330 is Industrial Injections latest turbo creation. Fits 2003 – 2007 Cummins. It is built from a BorgWarner S330. It is offered in Dodge 3rd generation configuration only. It is equipped with a 62mm compressor wheel and the proven 74mm exhaust wheel. The exhaust housing measures 14cm and is custom built. The 14cm exhaust housing comes standard with large wastegate passages built at the factory with the intention of relieving exhaust pressure in a hurry. Most turbos are equipped with a 30 lb. wastegate actuator. The Thunder 330 turbo comes standard with heavy-duty, 40 lb. wastegate actuator. The journal bearings in the Thunder 330 are larger and wider than that of a S300. This give the Thunder 330 more of a hydraulic advantage to keep the rotating assembly centered at higher boost pressures. Most S300 turbos come with a four pad thrust; however, the Thunder 330 comes standard with a six pad thrust. Bottom line, the Thunder 330 is a powerfully built turbo at a great price. Requires 2 Piece maniflod, downpipe w/ clamp, coolant plugs and cooler plates for install.
