Part # TB401A-SB01A

The new Tomei ARMS MX7760 Turbo Kit for the 2002-2005 Subaru Impreza WRX GD and 2004-2014 Subaru Impreza WRX STi improves on one of the the best 100% bolt-on turbo kit in the market for OE response and characteristics. It exceeds all figures of power and torque from the OE turbo kit while taking full advantage of the EJ engine.

So what do you get in the MX series over the old M series? The MX comes with a billet compressor wheel that is lighter than the old cast version making it more responsive and allowing it to spool quicker. on top of that the MX comes with a new Multi Rate actuator than can use a combination of 3 from 6 springs to adjust to your specific boost setting.

If you are looking for a hassle free turbo upgrade that maintains OEM characteristics with equal response and increase in peak power then this is the ideal turbo kit upgrade for you.
