1997 eclipse gst. how to reinforce automatic transmission?

Consider converting over to manual, running that much boost on a automatic will require forged gears which can get costly since you will require stronger gears to support the amount of torque/hp an the gears will require proper time tuning to shift at the precise time so you get as much power down to the wheels, not to mention upgraded internals/external bolt ons considering you want to run 16-18 psi continuously.
