    2G N/T HP Upgrades

    Non-turbo DSMs that were built from 1995-99 have a 2.0 liter, 140hp DOHC Chrysler 420A motor. These motors are completely different from the Mitsubishi 2.0 liter motors and their parts are not interchangable. To get more performance out of these cars, we've outlined a few possiblities below. Of course, some mods may not adhere to various vehicle emissions laws, so perform at your own risk.


    All-Motor Upgrades

    1. Air Intake
      Replace your stock air box with a solid pipe and high-flow cone filter.
    2. Cat-back Exhaust
      Replace your stock cat-back exhaust with a higher flowing model.
    3. High Flow Cat
      Replace your stock catalytic converter with a higher flowing model.
    4. Exhaust Header
      Replace your factory exhaust manifold with a tubular steel header.
    5. Bored-out Throttle Body
      Increase the opening on your throttle body to increase air intake.
    6. Ported Intake Manifold
      Further increases air intake.
    7. Camshafts and Cam Gears
      Agressive camshafts and cam gears allow for more power through timing adjustment.
    8. Underdrive Pulleys
      Underdrive pulleys can be added at the same time to reduce weight, which means the engine will work less to drive the accessory belts.
    9. Cylinder Head Porting
      Greatly increase air flow through the cylinder head. You may need to compensate with more fuel, which means you'll need an aftermarket Air/Fuel Controller.
    10. Air/Fuel Controller
      Allows tune-ability of the air/fuel mixture to avoid detonation and major engine damage.
    11. Ignition Timing Controller
      Allows you to control the timing.

    Forced Induction Options

    1. Turbo Kit
      Bolt on a turbo kit for a huge power increase. Many of the All-Motor upgrades can and should be used along with a turbo kit for maximum power output. To learn the basics on how a turbo system works, click here.
    2. Nitrous
      The fastest and easiest way to bolt on big power. It's also the fastest and easiest way to destroy your engine if you don't know what you're doing. Read up on nitrous systems before considering one.
    3. Turbo Engine Swap
      This project is extremely time consuming, complex and expensive due to the amount of parts needed to perform the task. The parts alone can range upwards of $5000. The basic parts needed are: Engine, transmission, ECU, intercooler (and piping), fuel pump, complete exhaust system, and possibly a few more things not mentioned. The two options above are definitely better choices for the less experienced. Consider the cost of simply buying a factory turbocharged DSM before attempting this swap.
