The VF34 is the standard equipment turbocharger used on the JDM V7 Subaru Impreza WRX STi Spec-C. The VF34 is nearly identical to the VF30 but has improved spool up due to its dual ball bearing RHF5HB CHRA design. It utilizes a P18 exhaust housing, F55 turbine, and model 479 60 trim compressor wheel as found on other STI turbos.
It is a bolt-on direct replacement for the single scroll WRX or STI application. When upgrading the WRX turbo injector and/or tuning will be required to ensure reliability and performance.
