IHI Subaru Genuine VF34 Turbo 14411AA321

This model turbo is the latest bolt on upgrade for the WRX. It is standard on all STI models as of late 2001. The VF 34 has the same specs as the VF30 but features a ball bearing cartridge assembly. The VF34 will spool up approximately 250RPM quicker than the VF30, making it a good all round performer. Ball bearing turbo with a 479 comp wheel and P18 turbine housing.

All IHI VF turbos are a bolt-on for Subaru EJ20, EJ22 & EJ25 engines.

The VF34 is a good comprimise and is still capable of holding boost pressures to higher RPM than the standard TD04 turbo, but will spool up quickly. It will still be slightly more laggy than the TD04 but not really all that noticeable.

The VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30.

Warranty Notes:

• It is extremely uncommon for turbos to fail on their own and any failures are usually attributed to external influences such as oiling, debris and blow-by.
• In the event of a warranty claim the customer is reposnsible for any costs incurred for shipping and inspection. If a warranty claim is approved these costs will be refunded.
• If replacing a previously failed turbocharged it is imperative that the cause of failure be investigated. If the turbo failed due to another component on the car it is likely the new turbo will fail again, in which case no warranty will be approved.
