nice write up. now you can add this one:
Forced Performance - 68HTA (Bolt on)
FP's newest turbo is the FP 68HTA™Turbocharger for the Subaru STi/WRX unit which out flows both the E316g and 18g wheels and allows for higher PR operation without increased compressor outlet temperatures like the existing 16g and 18g wheels. Mass flow is increased to a whopping 47lb/min which is several lb/min greater than either the E316g or the 18g wheels are capable of. Rapid spool and large torque numbers are guaranteed by the TD05H turbine section.
These units are constructed from Genuine MHI 16g turbochargers which are reconfigured to 68HTA specs by Forced Performance.
