| IHI VF Series Bolt-on Turbos for 02-07 WRX & 04-09 STi |
 |
IHI turbos are a direct bolt-on for the 02-07 WRX utilizing the factory mounting points and attaching to the factory oil and coolant lines. Although these are a great upgrade for a 2.0L WRX, any 2.5L WRX should be considering some of the larger options as the power gains from the IHI turbos will be minimal (The VF39 is the OEM 04-06 STi turbo, the VF43 is stock 2007 STi turbo, and the VF48 is the 08 STi turbo so they are not upgrades for these cars). |
IHI VF39: The IHI VF39 comes stock on the 04-06 US Market STi, and is a well proven upgrade path for the WRX. The VF39 uses a thrust bearing setup with a P18 exhaust housing capable of 285 whp* on the EJ20. If you are considering the VF39, we highly suggest checking out the VF43 as it is a better setup in the same class.
IHI VF43: The IHI VF43 comes stock on the 2007 STi. It has almost identical features of the VF39 with a thrust bearing and a P18 exhaust housing, but the wastegate opening is larger to relieve boost creep issues. The VF43 is capable of 290 whp* on the EJ20.
IHI VF48: The IHI VF48 comes stock on the 2008 STi. Not much is known about this turbo yet as it has recently been introduced, but it has already made huge power numbers on the 08 STi.
* Wheel horsepower numbers provided are estimates to help turbo comparisons. They are by no means exact prediction of the power output as these numbers can easily fluctuate 15% based on many factors ranging from type of dyno to supporting modifications. |
