I have gotten word that the turbo in the STi is possibly a IHI VF30 Ball-Bearing. Not bad for a start..

What's the difference between the VF30 and the VF34? Which one is in the Spec C, which also gets a ball-bearing unit?

Actually I am hearing vf 39 !

Actually the VF30 is not a ball bearing turbo. I would say it is a rather old turbo. The VF30 ball bearing turbo version is the VF34. Which also has been around for a year or two.

People have mentioned that they have seen the "outside" of the turbo in the car and it seems to be a VF30/34 housing. But who knows for sure.


By the way the V30-34 have ben installed as part of staged packages by
the WRX tuners. It can do a lot more thatn 14-15 psi (probably easily 18psi)

Official press release w/hint of delivery date.

Trust me on this one. It is the Vf -39 Shares the housing with the vf-30 though.
Vf -36 is the twin scroll.

What are some of the specs on the VF-39? Will be upgrading to anything else, or does it have big power potential on it's own...

Can you post any of the specs on this turbo?

 

[alfredob1]

Mr. Glen Wallace over at NASIOC either first said it was or confirmed that it was a VF39. He has his source but it didn't reveal it (I believe).

FREE ICE CREAM!!

Yes Glen is the one that confirmed it to me. But he won't give the specs yet. I am pretty sure it is a completely new turbo cause I have not heard anything on it. Should be quite interesting. Wish I knew more guys. Give me time It's good to know people lol

I looked and read everything about the STI specs nothing about what Turbo there going to use. I would just like to know the Size??

Blue it's definately the vf39 we just don't seem to have the specs for it. I am going to try to contact ihi and see if they can give them to me.

The VF39 is the biggest turbocharger Subaru makes then? What size turbo does the EVO have? VF39 that sounds huge. I think the biggest I read was a VF34.

 

[CloNeGTS]

Subaru doesn't make turbos....IHI builds the VF series turbos. From what has been said, the VF39 is a new model made just for the STi.

The turbo 'size' (if you wanted to simplify it as a single magnitude) can't be determined by the number. The VF34 is not the biggest IHI found on a WRX. The VF22 is. The rule is, the higher the number, the newer the turbo. That's how it typically goes (there are exceptions irrc). So, the number/name doesn't tell you anything we don't already know.

 

[Need4Speed]

Hmmmm.... I had always understood that the VF-22 was actually, technically a larger turbo than the VF-30 ....... more of a drag type turbo ......

edit: that's funny, didn't see the post above ...

 

[BoostedBoxer]

well isnt the vf22 bigger than then vf30? so on that path....the vf39 would be smaller than that and the vf34

godspeed doesnt seem to think its very big...


the evo has a td05-16g....step up from the wrx td04

edit: didnt see the previous 2 posts

WHAT THE HELL DOES THE VF STAND FOR?

We have dyno tested and additional 57hp @wheels on the STi with the AVO 450hp turbo and 3" turboback exhaust. Not bad for just changing the turbo and some exhaust.
