MitsuStyle - View Single Post - Important information for owners of MAP EF series turbochargers for Evo X

**v8klla** · 10-03-2012

Recently we received a handful of reports from Evo X turbocharger owners that seemingly out of no where began experiencing issues with loss of preload and as a result slow spool characteristics. Upon further inspection it was realized that the issue was not the actuator, rather it was the wastegate flapper and arm which were deforming due to prolonged exposure to high exhaust gas temperatures (predominantly road race vehicles).

As MAP turbochargers are intended for use in even the most extreme environments, a failure like this is simply not acceptable. With that being said, we have been working diligently with our supplier and have developed a solution that involves replacing the wastegate arm and flapper with components manufactured from a different, more heat resistant metallurgy. Effective October 1st all new Evo X EF Series turbochargers shipping from our facility will include these upgraded components.

Unfortunately, for existing turbochargers these new components must be installed into the turbine housing which requires removal from the vehicle (removing the downpipe first and then the turbine housing only whilst leaving the rest of the turbocharger and manifold in place is recommended) and forwarding to our facility. We will be happy to facilitate shipping both ways, there is obviously no cost for this service, and we are also offering an exchange program to minimize downtime for our customers.

If you find yourself experiencing issues with loss of preload and resulting slow spool characteristics (or if you simply want to be proactive) please follow the link below to submit a ticket via our support help desk and we will be in touch promptly to begin the exchange process.

Although this issue has occurred in a very small percentage of our turbochargers my sincere apologies go out to those that were inconvenienced by this situation. We will do our best to make up for this shortcoming and learn from this experience to ensure our products meet or exceed what the marketplace has come to expect from Modern Automotive Performance.
