Subaru WRX STI Performance Parts Modification Guide

 

The Subaru WRX STI is an excellent performance car with its solid braking system, high-powered suspension, 300 turbocharged horsepower, and unadulterated all-wheel traction. It is an undeniably amazing vehicle, but you can still improve its performance with a bit of modification here and there.

 

Here is a short but brief Subaru STI performance parts catalog for your next modification project:

 

  • If you want to make your car a tad faster without voiding manufacturer’s warranty, we highly recommend reflashing the engine control unit or ECU. This modification will also add more horsepower to your stock engine HP and overall torque without any major changes.

  • One of the major factors that affects Subaru performance tuning is the exhaust system. Replace the stock exhaust system with a 4” Turbo Back Exhaust setup. After this modification, expect your car’s engine to be louder, with power not going lower than 80hp.

  • For more power without compromising your vehicle’s handling, reliability, and efficiency on the road, experts highly recommend the inclusion of front-mount intercooler, headers, boost controllers, and larger fuel injectors. These Subaru factory performance car parts may be added one at a time. You should never rush into replacing parts for your car as this may prove to be an expensive activity in the event that replacement parts do not function well with the rest of a Subaru’s other parts and components. f

  • For those with sufficient budget for major modifications, your end goal is to replace your stock Subaru WRX STI stock turbo with a powerful aftermarket beast. If your goal is to install a larger turbo setup with 450 AWHP power, at most you will be spending between $15,000 to as much as $80,000 or beyond to make your Subaru STI drive, sound, and feel like a dream.
