T25-T3 Adapter Flanges are currently on back-order for 4-6 weeks.

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.

 

Wanting to upgarde your turbo and THEN your injection pump? This is the turbo for you! It performs much better than the 2 factory turbos, even with the stock pump. After you add your Dieselmeken pump, it gets even better! The HE221 7cm² offers the best compromise for all-around performance with an OM617 fitted with Dieselmeken 7.5mm injection pump. It offers quick spooling with 2psi boost by ~1200 RPM. Drive pressure's are minimal at the wastegated 26psi boost pressure. EGT's are extremely low compared to the factory turbo's. This turbo has a T25 flange.

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.

Please note that you may receive a turbo that says either HE221 or HE200. Because of varying availability, I sell multiple different part numbers that are all the same physical 7cm² turbo.
