Turbo VF Series	VF35 The VF35 is the standard turbocharger used on the JDM Subaru Impreza WRX. The VF35 is similar to the VF34. using the same compressor housing and compressor inducer size.

This allows the VF35 to spool slightly earlier than the VF34 at around 2800-2900 at the cost of less top-end performance. Expect to achieve full boost (with the proper mods and mapping) between 2900-3300rpms and will probably max out at around 325bhp. £1450 inc VAT
