HE351CW Compressor Wheel Upgrade

Below I will introduce you to our available billet compressor wheel options 60mm 62.45mm and 67mm. But first here are the factory specs.

2003 – 2004 Dodge ram 2500 & 3500 factory turbo specs: 54mm x 78mm or 56mm x 78mm (7+7 blade) compressor wheel, and 58 x 65mm turbine wheel.

2004 – 2007 Dodge ram 2500 & 3500 factory turbo specs: 60mm x 86mm (hx40 7+7 blade compressor wheel)

Our upgraded compressor wheel and housings are for the 2004.5 -2007 Dodge ram with the 5.9 cummins, if you want to use our compressor housing and wheel on the 2003 – 2004 model, the bearing housing will have to be machined to fit the larger exducer of the compressor wheel (factory is 78mm and the upgrades range from 86 to 89mm, the bearing housing’s compressor wheel pocket has to be machined 1.2mm larger than the compressor wheel) or you can buy our HE351CW bearing housing from our Ebay listing which is machined for our 67mm compressor wheel and compressor housing oring. . Also the boost control solenoid will need to be deleted to work on the 2003 – 2004 model turbos. There are block off plates available on Ebay as well.

Here are our compressor wheel and housing upgrade options for the 2005 – 2007 5.9 Cummins turbo models: 62.45mm x 86mm 650hp option (click to buy from our Ebay listing) and 67mm x 89mm x 95mm 725hp option (click to buy from our Ebay listing). It is recommended to use our turbine housing and turbine wheel in combination of the compressor wheel upgrade, to increase hp and lower EGTs and drive pressure. We also have built turbos available. We also machine our bearing housings for O-rings to insure that the compressor housing will seal properly, the turbo original does not have a seal for the compressor housing.

6.7 Cummins Turbo Upgrade Problems

When upgrading a 6.7 cummins turbo charger is it important to understand that you can create problems. In summary, the larger turbo is increasing the amount of airflow being pressed into the engine, as well as being removed from the engine. However downshifting with combination of using the exhaust brake can cause compressor surge. Compressor surge is when the turbo is trying to compressor more air into the engine than the engine is capable of disposing of out the exhaust system. The reason this is such a major issue with VGT model turbo chargers is because the VGT system is used as an exhaust brake. When the VGT System is used as an exhaust brake, it spools the turbo to high rpm, because it is closing the Vane for the VGT system to work as an exhaust brake which is also the same way the VGT System is used to spool up the turbo charger.

There is a fix for this issue. A blow off valve kit can be used to relieve the pressure between the turbo and the intercooler, but you need a kit designed for diesel. XDP has the best kit that i have seen, that is available here. Compressor surge becomes a major problem when the exhaust brake is on and the driver is down shifting into lower gears which is increasing the output boost from the turbo charger, but at the same time restricting the pressure from escaping turbo. I didn’t have a problem for years with the modified turbo chargers, because the problems of the upgraded turbo chargers for the 6.7 cummins is dependent on the driver. It depends on how the driver operates the vehicle. If the truck is has an automatic the transmission is controlling the gear selection when driving, the driver can also select tow mod, which will engage engine braking. With a manual transmission, the driver controls how low of a gear they want to select, in which the driver can control the amount of strain on the turbo.

The stock turbo failing from engine braking with the exhaust brake is not as common, but it is common for the strain of turbo to be heard, which is commonly referred to as turbo bark. Turbo bark term used to describe the sound of compressor surge. It is much more common for an upgraded turbo to break in compressor surge conditions because of the increased airflow. The t51r version of the turbo is much more likely to have problems because the anti-surge, doesn’t allow as much relieve as a stock compressor housing without the t51r.

If you plan to use an upgraded turbo, but you don’t plan on towing, you likely wont need the blow off valve, but if you plan on towing then you need the blow off valve to protect your turbo from ripping the blades off due to compressor surge.

89 – 02 12v & 24v HX35 HX40 67mm Turbine Housing & Wheel Upgrade

HX35 64mm x 76mm turbine Wheel and exhaust housing upgrade.
Please Read Carefully: This Housing is made to directly fit 1989 1997 24v turbochargers as a upgrade.  To work on other models modification is need as listed below:

1989-1997, have some variations of the factory turbo charger, this turbine housing and wheel work as an upgrade to the H1C and HX35, even though there are different version, in which some did not include wastegate actuators, this housing is still a direct fit on the factory turbo chargers in combination of using the turbine wheel included. This kit is intended to be used with a compressor upgrade 60mm, 62.45mm, or 67mm.

The turbine housing in this listing has 4 drilled through holes at the t3 flange, because the 12v engines use 4 studs threaded into the manifold. The 24v cummins (98- 02) has 2 threaded holes on the turbine housing and 2 threaded holes on the manifold to use studs. If this housing is used on a 24v cummins, 2 bolts and nuts will need to be used to bolt on the turbine housing because the exhaust manifold and turbine housing is not threaded for studs and the manifold is only threaded for 2 studs. If you are using this kit on a 24v you will not need to use the factory 24v wastegate actuator and mount on the compressor housing.

If you are using this turbine housing on a 12v turbo with a horizontal mounting wastegate actuator, no actuator, or vertical wastegate actuator, this is a direct fit.

Modifications Required to fit 12v model turbos: (there are 2 versions of 12v Engines)

-To fit 12v turbos normally using horizontally mounted actuators, the threaded holes must be drill on the t3 flange for the manifold studs to go through the turbine housing. (thats it!)

Some 12v models cannot use the horizontal actuators because they interfere with the oil drain which won’t allow the turbo to bolt on. However, the vertical mounting wastegate actuator is universal, there for this turbine housing upgrade is a universal fit for both model 12v engines.

Details of the listed items:

Upgrade for the 12v & 24v 5.9 cummins

Includes:

  • Fits 1989 – 2002 12v & 24v cummins factory HX35 turbo as upgrade
  • Direct fit for 1989 – 1997 12 valve turbo chargers / engines
  • 2 bolt and nuts are needed to fit 1998 – 2002 24v because no threaded holes on t3 flange (no threads for studs)
  • HX40 67mm x 76mm turbine shaft

98 – 02 24v HX35 HX40 64mm Exhaust Housing Upgrade

HX35 64mm x 76mm turbine Wheel and exhaust housing upgrade.
Please Read Carefully: This Housing is made to directly fit 1998 -2002 24v turbochargers as a upgrade. To work on other models modification is need as listed below:

Modifications Required to fit 12v model turbos: (there are 2 versions of 12v Engines)

-To fit 12v turbos normally using horizontally mounted actuators, the threaded holes must be drill on the t3 flange for the manifold studs to go through the turbine housing. (thats it!)

-To fit 12v turbos normally using vertically mounted actuators, the threaded holes must be drill on the t3 flange for the manifold studs to go through the turbine housing, and the wastegate arm must be repositioned to operated vertically rather than horizontally. The arm must be cut off and rewelded. (Some 12v models cannot use the horizontal actuators because they interfere with the oil drain which won’t allow the turbo to bolt on. 

Explanation of the fitment Modification:

This is a custom made housing, the t3 divided flange is threaded for 2 studs for the purpose of bolting onto an HX35 Dodge ram 1998.5 – 2002 24v exhaust manifold. If you want to use this with a 1989 -1998 12v manifold, the threaded holes will have to be drilled out larger on this turbine housing for the 12v manifold studs to allow the turbine housing to bolt on. (The 12v Exhaust manifolds have 4 threaded holes for studs on the manifold).  In addition, this turbine housing is designed to be used with wastegate mounted to a 24v 1998-2002 compressor housing or you can use a 12v horizontal mounting wastegate actuator + mounting hardware, but only on 24v engines or 12v engines where the horizontal actuator wont interfere with the oil drain. 

This turbine housing’s wastegate arm can be repositioned (cut off rewelded) to work with vertically mounted wastegate actuators, but not every 12 valve engine will allow a horizontal actuator to bolt on because the oil drain on some 12 valve engines will be in the way not allowing the horizontal actuator and turbo to bolt on. In summary some 12v engines can use a horizontal mounting wastegate actuator & Turbine housing and some cannot, but the turbine housing’s wastegate arm’s position can be changed to work with a vertical or horizontal mounting wastegate actuator, but you must have the matching wastegate actuator and mounting hardware. At the time of this writing, i only have the vertical mounting wastegate + hardware.
