Blouch 18G-XT Turbocharger (WRX & STI)

The turbo experts at Blouch Performance Turbo could not resist applying their latest "XT" billet compressor aero to the venerable 18G.



Blouch Performance Turbo was founded by Robert Blouch Sr. in February 1980. His son, Bob Jr., joined the business in 1990 and spearheaded the development of bolt-on upgrade turbos for the emerging four cylinder sport compact market. Blouch Performance Turbo offers a complete line-up of custom performance bolt-on upgrades for popular vehicles such as the Subaru WRX/STi , Mitsubishi EVO VIII, IX and X, Porsche 996 and 997, Mitsubishi 3000GT, and Dodge SRT4 and Caliber. The components used in these upgrades are state-of-the art such as fully machined billet compressors with advanced aero, custom turbine wheel and shaft assemblies, and custom compressor and turbine housing castings that are machined in-house on our own CNC equipment.

 Here's the skinny:

  • TD06 compressor housing custom CNC machined at Blouch Turbo for the new 18G-XT aero
  • Closed die forged fully machined billet 18G-XT compressor wheel that is lighter yet stronger and more efficient with greater flow rate
  • Genuine Mitsubishi center housing with all genuine Mitsubishi parts
  • Mitsubishi TD05H turbine wheel
  • Options of 7cm2, 8cm2 or 10cm2 turbine housings tailored to your application
  • Upgraded actuator option
  • Complete drain tube/coolant line package with gaskets for a complete bolt-on package

 So what's the big deal? The new Subaru 18G-XT outperforms the "old" 18G by producing more peak torque and providing greater mass flow at high RPM's for even more peak horsepower. On the street, these turbos are incredible!

 If you order the Up-Graded Waste-gate or require a diameter turbine housing other than the 7cm2, please be sure to specify what pressure or size you want in your order notes.

 Because of all the possible options, these turbos are built to order, so please allow a few extra days for shipping.
