Blouch 16G-XT Turbo

The Blouch 16G-XT offers you the most bang for your buck in a 16G upgrade platform for the WRX/STI.



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.

The Blouch TD05H-16G-XT features the 41lb/min proven performance of the 16G state-of-the-art machined billet compressor design combined with the quick response and high flow capacity of the TD05H turbine. The 7cm2 nozzle area turbine housing includes an internal wastegate port and standard wastegate actuator calibrated at 18 PSI.

The WRX/STI TD05H-16G-XT is a direct bolt on upgrade shipped complete with coolant pipes and turbo oil drain tube installed and requires no modification to intake, exhaust, oil and coolant connections for installation.

HP Bolt On:

"We still feel that this is just about the ideal turbo up-grade for any of the 2.0 liter WRX's out there because it offers good spool for a wide power-band, while also providing good top-end power as well."
