This specific turbo is on back-order indefinitely. I will make an announcement when they are available again. Order only if you don't mind waiting.

 

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. 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:

-Turbocharger

-T3 Gasket

-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:

-Compressor Outlet Elbow (90°) with Ø2.5" barbed outlet

-OM617 HE-Series Oil Drain Kit (save $ by ordering here - leave preference of clear or gold anodize in comments during checkout)

-Oil Feed Line Kit (36" for OEM Filter Housing, 38.5" for Doomsday Filter Relocator)
