New option of performance turbo for EJ Single Scroll!

The all new T390M turbo kit designed to best perform especially with EJ20 Single Scroll.  Well balanced for quick response from the low range to the top power at the high RPM range!  It comes with the same billet compressor wheel as the existing T440M turbo but covers wider range of different needs while the T440M turbo kit is mainly for tuned EJ25 and long-stroked EJ22/EJ26. T390M offers well tuned low-mid torque that a 2.0L engine can spool up smoothly to the high end range. Stress-free and easy drivability from the street to sport driving on small tracks. The ARMS series turbo kits all come supplied with all the required gaskets and fitting, no modifications required.

Compressor Wheel

The all new, forged aluminum billet compressor wheel increases even more efficiency and at the same time reduces surging that is one of the well known problems on tuning especially with AVCS applications.

New Housing for More Efficiency

Redeveloped from the material for more efficiency to convert the energy straight to power with better lubrication and cooling.

Floating Metal Bearing

 High quality floating journal bearing at the center shaft.

Reinforced actuator

Remarkable stability under high boost.
