Looking for the ultimate turbo upgrade for your stock OM617? Want supercharger response? Don't want the hassle of adding an intercooler but want lower EGT's? This turbo is exactly what you need!


Seeing "Holset" turbos elsewhere for far cheaper? Do they look too good to be true? They are likely counterfeits. Ebay is certainly flooded with them. They're picking up on this, and I am now seeing counterfeits being sold for just dollars less than mine! Aside from a turbo that actually comes from Holset, what do you get with this purchase? You're supporting my testing of turbo's. Without these sales, I would not have been able to test 24 different OM617 setups. OM602, OM606, 4BT, and 6BT tests are soon to come, followed by even more engines.


HE200 5cm² differences. This is the HE200 5cm² with a larger, more standard 3" inlet. It has an anti-surge feature that keeps the turbo from barking when you are under load and suddenly let all the way off the throttle. This will reduce the stress on the turbo shaft and blades. It is marketed towards manual transmissions since you are constantly letting off the throttle to shift. Furthermore, you can remove the silencer ring that shrouds the anti-surge inlet to get an ear-bleeding turbo whistle. If you are going to run compounds or are wanting to run the Bolt-On Kit, you should purchase the 60mm non-anti-surge inlet version, instead. Again, THIS IS NOT COMPATIBLE WITH THE BOLT-ON HE200 KIT.


Doomsday Diesel has performed extensive testing on nearly a dozen different turbo setups to find the perfect match for the factory 5.5mm injection pump. While both factory turbo options are slow to start spooling around 1800 RPM, this HE200WG provides 5psi of boost by 1200RPM!!


Also works with the 7.5mm Dieselmeken injection pump upgrade! Just runs a bit hotter than the 7cm² turbo. It's certainly recommended you go with the 7cm² if you're planning to run a 7.5mm pump.


The factory turbos both offer excessive EGT's at mid-to-high RPM. This is partially due to their restrictive wastegate setups, but also simply due to their mismatch for the OM617. Drive pressures with the factory turbos put lots of extra strain/load on the engine, while pushing EGT's to unsafe levels. This HE200WG runs super-cool at lower-to-mid RPM. The trade-off for the low-end response is a restriction at high RPM. This HE200WG supports nearly 22psi in stock form vs. 9psi with the factory options, all while running MUCH cooler than the factory options set at 9psi! This turbo performs like a supercharger. You will have nearly immediate boost off-idle. You will be able to cruise with far lower EGT's than stock. When pulling a grade, you will find less downshifting is required, as well as lower EGT's. You will also find more power at lower RPM due to the increased efficiency of this turbo.


If operating at high RPM for sustatined periods, you must pay attention to EGT's, as they will start to climb when driving at sustained speeds of over 4000 RPM. If operating at high RPM for short bursts, such as before shifting gears or to pass a vehicle, you will find this HE200WG to perform better than the factory options.


What's included:


-T3 Gasket

-Oil Feed Kit for OM617 (Call/email if ordering turbo for different engine)

-90° Compressor Elbow w/ v-band clamp and Ø2.5" outlet

-Exhaust flange and gasket


When installing, oil feed and drainage are critical to the proper function and longevity of the turbo. Find the turbo mounting requirements in the Tech Info section. The oil inlet is M10x1.25. If you are unsure about your setup, contact me to discuss. This turbo has a T3 flange and will bolt directly to the OM617 exhaust manifold without modification.


Optional accessories include:

-OM617-specific oil drain (clear or orange) or just the HE221 drain flange with 10" of hose and clamps

-DIY Intake Manifold Modification Kit

-2.5/3" Downpipe Adapter Flange w/ V-Band Clamp


USED Turbo Option:

In an attempt to offer an economical option for those who really want to solve their EGT problems but can't quite afford a brand new turbo, I'm offering "factory take-offs" that do not include warranty of any kind. These are turbo's from completed engine assemblies that did not pass the final QA steps at Cummins. The engines get test-fired to verify everything works. These turbos are "used", but in reality, they've only been run on the test stand. The engines are painted before test-firing. The paint has been removed from these turbo's, but you may still find traces in some areas.




Intake Modification Service:
What you will receive is an intake manifold with the factory inlet and EGR capped off, and a Ø2.5" beaded tube welded to the center of the manifold. You will need to, again, clean the manifold before installation, as I do not have the capability to clean these in bulk at my shop. You must send me a CLEAN core to 3901 address on website. Clean both INSIDE and out. Use a pressure washer, Super Clean or Easy Off, and a toilet brush to THOROUGHLY clean. Any units not clean enough for welding are subject to a $50 fee. I usually have units in stock, already modified to expedite turnaround. If you want your own manifold back, just let me know in Notes at checkout. If your manifold is not received within 30 days of purchase, the service will be forfeited at your expense.
