Turbos on Twin Turbo Subaru Legacy/s


gtlegacy

Recommended Posts

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?

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

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

Ray, you should have the 33/32

(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.

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.

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 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.

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.

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.

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

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
