IHI Subaru Genuine VF48 Turbo - Subaru WRX/STI - 14411AA700 available on AfterPay. We deliver Australia-wide! – Sydney, Brisbane, Melbourne, Adelaide & Perth.
The Subaru OEM IHI VF48 turbocharger is a direct bolt-on option for the WRX & STI, utilizing the factory mounting points and attaching to the factory oil and coolant lines. This turbo is a great upgrade option for 2.0L WRX owners looking to make significantly more power and still retain OEM quality and fitment. 2.5L WRX models (2006-2007) will also benefit from a VF48 turbo upgrade, however gains will not be as dramatic as on the 2.0 models as the larger displacement motor will suffer from a taper in power in the high RPM range. STI owners should consider this turbocharger as an OEM replacement only. As with all turbo upgrades, this turbo will require fuelling and tuning upgrades to operate safely.
The IHI VF48 comes stock on the 2008+ STI. This turbo has shown to produce numbers of around 300-315whp when tuned aggressively.
This is the standard equipment turbocharger used on the Subaru WRX STI MY08-10. The primary difference between the VF48 and the VF43 used previously on STI's is the more advanced bearing design. Expect to achieve full boost with the proper mods and a quality tune between 3000-3500rpms.
2001-2007 WRX owners will need fuel upgrades for this turbocharger and proper engine management is highly recommended for all vehicles.
*This turbocharger is not a direct bolt-on for the MY08+ WRX.
