STi Turbo

JJ · 04-19-2003, 08:12 PM

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

Agent Chobos · 04-19-2003, 10:04 PM

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)

Cheers

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 · 04-29-2003, 09:29 AM

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).

O4STi · 04-29-2003, 03:43 PM

i think people in hawaii should do everyone a big favor and take out the turbo. now wouldnt that be great so we get the REAL answer? LOL i wouldnt do that though =( but plzz?

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

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.

STIBLuE · 05-10-2003, 03:41 PM

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 · 05-10-2003, 05:04 PM

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.
