When it comes to aftermarket turbochargers for this particular platform, Blouch Performance Turbo is among one of the more popular choices among enthusiasts because they are built using careful manufacturing methods to produce a more powerful direct bolt-in option. On this page, you are looking at their TD05H-18GXT 7cm2 turbocharger.
Investing in a larger turbo as well as supporting mods is one of the best power upgrades you could buy. Blouch is the leader in turbo development; they consistently build the best turbos. This is a perfect turbo for your 400 HP WRX or STI. The new XT line of turbos from Blouch consists of a billet compressor wheel to optimize the aerodynamics of a turbo and increase compressor flow within the same inducer geometry.
The TD05H-18GXT features the 40 lb/min performance of the Mitsubishi TD06 18G compressor wheel combined with the quick response of the TD05H turbine wheel. To maximize compressor efficiency, the WRX/STi TD05H-18GXT 7cm2 utilizes a true TD06 compressor housing with custom actuator mounting in place of the TD05 housing. Standard wastegate actuator is calibrated at 9 PSI.
To maintain proper boost control, the TD05H-18GXT utilizes a ported turbine housing that is included in the price of the turbo. Like all of Blouch's WRX/STi bolt on upgrades, the TD05H-18GXT is shipped complete with coolant pipes and turbo oil drain tube installed to simplify installation.
