This is the EVO6.5 RS T.M.E Titanium shaft turbocharger with larger 10.5cm^2 Turbine housing. Fits all EVO4-EVO8 cars and offers a larger, less restrictive turbine housing made in A3N material that is less affected than the standard F5 material by anti-lag systems and elevated EGT's.
The Titanium Aluminide turbine wheel and shaft is 33% lighter than the standard Inconel 713C turbine wheel and shaft. This enormous reduction in the rotating assembly inertia is Mitsubishi's response to the demand for ever increasing shaft acceleration rates and decreasing turbocharger spool-up. The Titanium Aluminide material is also significantly more stable at 1600F than Inconel 713C.
The effect of increased lag of this larger exhaust housing is more than offset by the increase in spoolup provided by the lighter rotating assembly, resulting in faster than stock EVO8 turbocharger spoolup with increased top end power.
TECH TIP: Direct bolt on turbo.
Fits: Mitsubishi Lancer Evolution VIII
