Update 2023 - new cast cover with 90 degree. We no longer weld an elbow to the outlet of the SXE cover, we use our new casting.
Since SEMA 2014, we have all fallen in love with Borg Warner's factory-built SXE Billet (FMW) Wheel and 360 degree thrust bearing kits. Here at AGP, we've decided to offer up the perfect divided turbine housing specific to the 5.9 Cummins Common Rail (3rd Gen). We offer both a 14cm (.80 A/R) housing conjoined with all the different compressor and turbine configurations. We cast our own compressor cover to mate up with your factory boost tube, and the turbine outlet flange is the 4.4" HE341/HE351 with the correct offset to bolt to your exhaust elbow.
Here's the long list of all the available configurations, however the most popular ones are going to be the 62-68-14 and 63-68-14. But, some of you will run a ton of fuel and be able to light one of the larger 64.5 and 66-73 turbos, so go right ahead and slap that charger on.
--UPDATE 10/1/17-- We have decided to include a turbo just smaller than the 62-68 for those guys needing every little bit of spoolup and low RPM cleanup as possible. For high elevation and / or manual transmissions, this 61-65 fills that void between the S300G and the 62-68. We have dubbed the 61-65 as the newest smallest turbo in the SXE lineup. This slightly smaller turbine wheel will aid spoolup by 100-150 RPM and only slightly restrict airflow above 3000rpm. This 61-65 incorporates the Billet (FMW) wheel and the 360 degree thrust bearing. Unfortunately the cost and labor involved with this combination equals a slightly higher price tag, but for those who really need it, it's now available.
Turbo will come complete with two exhaust studs, 3/8" Flat Face oil feed fitting, divided turbine inlet gasket, and oil drain gasket. There should be no other parts you need to purchase to bolt this turbo on.
Non Gated vs. Gated:
Simply put, a wastegate on a diesel opens to control turbine speed and drive pressure. When the wastegate opens and it relieves that drive pressure, it also slows down the turbine wheel thus creating less compressor flow. When you decrease the compressor flow of the turbo, you are decreasing the amount of air that is flowing through the engine. If you are still commanding and delivering the same amount of fuel, you are now going to have more fuel than air when the wastegate is opened. When you have more fuel than air, your EGTs rise. The only way to decrease your EGTs, is to decrease fuel OR increase airflow. Having a non wastegated turbo will give you the amount of boost that the delivered fuel needs to sustain a usable EGT.
“But I want a wastegated turbo so I don’t overboost, what do you say about that?” Well, the answer to overboosting a single turbo is the fact you have too much fuel. If you are running a single S300 turbo and you’re running more than 50psi, you should be running a compound setup, or you should turn your fuel down. Wastegating the turbo to run less boost at that same fuel delivery is not the answer. The only thing that will happen if you wastegate the turbo in that scenario is high EGTs.
There are situations and systems that may benefit from a wastegated turbo, however for 9/10 customers, a non gated turbo is the simple answer. If you have head studs, which you likely do if you’ve done fuel modifications to your pump or larger injectors, then a non gated turbo is easy. We’ve matched these housings and combinations so they work very well on the 5.9 and 6.7 applications.

Much needed upgrade with simple setup and great customer support
These guys were awesome. I called them up and told them my situation and they got me steered straight no problems. My turbo rips and my truck is lifted 8 inches w/ 37s on 24s. Would highly recommend!
Great turbo so far! Nice and cool egts in my compound setup. Great quality looking as well!
So far I'm impressed, even going straight to the 66 from stock spools nicely very little lag and best part is bolt on with the t3 flange no adapter and clamps to stock exhaust elbow.
