TiAL MVI 2.5 Compact Internal Wastegate Actuator

The TiAL MVI 2.5 Compact Internal Wastegate Actuator Will Help You Get the Most Out of Your Turbo

The MVI 2.5 unit is TiAL’s compact wastegate actuator standing only 2.2” in height without fittings and actuator rod. This compact design makes it easier for installations involving confined spaces. This is TiAL’s new line of fully configurable internal wastegate actuators.

For turbo applications with internal wastegates such as the TiAL IWG series housing and TiAL Alpha turbo systems. This wastegate actuator is also designed as a more robust, more reliable replacement for OEM parts. Like all TiAL parts, billet construction means they are stronger and more durable than a stock actuator. TiAL’s focus on performance means boost comes on faster and hold on longer so in some applications you’ll actually gain power from changing the wastegate alone, for example when you’re changing out a stock wastegate actuator that leaks. See the wastegate spring chart below for reference.
