Turbos on Twin Turbo Subaru Legacy/s

Recommended Posts

Guest

just to hijack this thread, cause I dont want to create my own yet, Im pretty sure I have the 13/14 combo on my JDM 94 GT and have developed a nice little whistle, I was thinking of replacing them with the 18/19's

is this worth it

AND

what else would I have to do to the car if I where to upgrade the turbo's to this?

Will this bolt straight on to the BD5 1997 RSB? I heard the secondary is different.

The VF31/32 Combo is found on teh E-tune. Earlier BH/BE had the 26/27 combo (man) or 25/27 combo (auto) Not sure whether the rev. D used the 31/32 or 26/27 combo.

Rev d could even be an e-tune? I know not much about BH model codes.

etune was a cosmetic 'addition' that was found on the rev C or Rev D afaik. it affected nothing mechanically.

so i think you're statement is back to front in regards to etune & Rev D

so im picking a 31/32 on yours ray.

afaik, MY02 (RevD) came with VF33/32 and MY01 (RevC) came with VF31/32

Ray, you should have the 33/32

IHI VF22
(490cfm at 18.0psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the JDM V3 Subaru Impreza WRX and optional on the JDM Subaru Impreza WRX STi 22b. Of all the IHI models, the VF22 has the largest potential for peak horsepower, and is capable of supporting the highest boost levels. It is capable of running up to 25 psi. The VF22 is a roller bearing turbo that utilizes the P20 exhaust housing.
Expect to achieve full boost with the proper mods and a quality tune between 3200-3700rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF23
(388cfm at 18psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the JDM Subaru Impreza WRX STi 22b. The VF23 is a ball bearing turbocharger that utilizes the P20 exhaust housing like the VF22. This housing is mated with the smaller compressor housing of the VF24 for fast response and excellent low and mid-range performance. It does not have the same top end power of the VF22, but spools up slightly quicker.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF24
(425cfm at 18psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the JDM V4 Subaru Impreza WRX STi. This turbo shares its compressor housing with the VF23, however, this housing is mated with a smaller (P18) exhaust side. The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group-N rally cars.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF29
(425cfm at 18psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger on the JDM V6 Subaru Impreza WRX STi. The VF29 is nearly identical to the VF24, with the same compressor and exhausthousings. However, the compressor wheel in the VF29 has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such, this unit is typically chosen over the VF24. Has a different location for the pressure hose on the wastegate actuator.
Expect to achieve full boost with the proper mods and a quality tune between 2900-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF30

IHI VF35
(425cfm, 250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the JDM Subaru Impreza WRX. The VF35 is similar to the VF34. It utilizes the same compressor housing and the samecompressor inducer size. The differences are in the divided thrust-bearing design and the P15 exhaust housing. This allows the VF35 to spool slightly quicker than the VF34 at the cost of less top-end performance.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF36
(430cfm, 250-325whp, Modification Required)
This is the standard equipment turbocharger used on the JDM V8-V9 Subaru Impreza WRX STI Spec-C Type RA. The VF36 is a twin-scroll turbocharger that utilizes a ballbearing design, a P25 exhaust housing, and titanium aluminide (TiAl) compressor wheel for improved spool. It is essentially a fast spooling VF34.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles.

IHI VF38
This is the standard equipment turbocharger used on the JDM Legacy MY04-06. The VF38 is a twin-scroll that utilizes a Titanium turbine and shaft. This turbocharger yields tremendous spool-up but offers less top-end than the VF36/VF37. The spool capabilities of this turbo are demonstrated on the JDM Legacy GT, which reaches peak torque at 2400RPM.

IHI VF39
(250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the USDM Subaru Impreza WRX STI. It can be found on all model years from 2004-2006. The VF39 utilizes a thrust bearing design and the P18 exhaust housing.
Expect to achieve full boost with the proper mods and a quality tune between 3000-3500rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles that utilize this turbo aftermarket. Though they are prone to cracking, VF39’s can be had for very cheap if bought used.

Info
Info

IHI VF42
This is the standard equipment turbocharger used on the JDM Subaru Impreza WRX STi S203 and S204. The VF42 features a twin-scroll design with a slightly larger compressorthan the VF36/VF37 turbos and different turbine design (more blades). The VF42 is a roller-bearing turbo and is similar in size to the VF22 turbo, but the twin-scroll exhausthousing yields faster spool-up and a superior top-end.

IHI VF43
(250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the MY07 USDM Subaru Impreza WRX STI. It can be found on both base STI's and STI Limited's. The VF43 utilizes a thrustbearing design and the P18 exhaust housing. The primary difference between the VF43 and the VF39 used previously on STI's seems to be the stiffness of the wastegate. The VF43 has a stiffer wastegate designed to reduce boost creep issues.
Expect to achieve full boost with the proper mods and a quality tune between 3000-3500rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles that utilize this turbo aftermarket.

Info

IHI VF48
(250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the USDM 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. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and properengine management is highly recommended for all vehicles. This turbocharger is not a direct bolt-on for the MY08+ WRX.
Purchase

IHI VF52
(250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the USDM Subaru WRX MY09-10. This turbocharger is similar to the VF48 but utilizes the USDM Legacy GT-style housing.
Expect to achieve full boost with the proper mods and a quality tune between 2800-3300rpms. This is NOT a direct bolt-on for 2002-2007 WRX, but will fit the 2008 WRX and2005+ Legacy GT without modification.

Hi jumping this topic for some help. This list and many other lists are brilliant but none contain my turbo which is a VF51. Have been scouring forums and the net for more info on it but found nothing. Any insights from members would be appreciated
