I don't have a ton of cash, but make me an offer if you have one. Thanks!

 

find a VF39. They are a great match for the 2.5L w/AVCS.

 

vf34 has better spool and is a bit better on the top end, not to mention its superior waste gate design (ie not so small). So I am looking for a 34 .

 

if you find a late 05 VF39, then it will have the hotside from a VF34 (close enough) and you will not have the boost creep problem.

do a search and you will find all the markings to be able to accurately pinpoint a late model VF39

 

Yo man, a vf34 is a waste of time on the 2.5L. Its not much bigger than your Mitsu TD04. You will have torque, but that top-end is still gonna die....my 2 cents.

if you are going to upgrade.. then upgrade

if you do not have the money to do it now, save it and then when you do have enough, do the mod properly.

 

So would you guys recommend the VF34 as an upgrade for the 2.0L WRX motors?

 

in my honest opinion, the TD04 is as laggy as I would go. The 2.0L needs AVCS and a twin scroll setup. I've been tempted several times to go this route, but can't bring my self to do anything but a 2.5L upgrade.

It's all a matter of opinion, and purpose.

 

$400 with a ported wastegate

VF34 is a small upgrade for a 2.0L let alone a 2.5L. If I had to do it over, I would go 18G on my 2003 WRX. If I was upgrading a newer WRX with the 2.5L, I would go with a 20G minimum.

I think you should listen to others and wait until you can afford a good upgrade.

I can afford any turbo I want, but I just don't want to spend that much on my car considering the money I've put in thus far. For what I want to do, the 34 is a perfect turbo. The 16 18 and 20g's are all mutts - parts put together by whomever selling it. Everyone can tell me all they want, but with my own decisions thus far I think my wrx is setup very nicely, and its going to kill on the track. I appreciate everyones feedback on what I "should" do, but its not going to change my mind.

To mcdrama: Would be good, but it says that its waste gate was over ported :/. I dont really wan't to deal with that or go to an external waste gate setup. I really appreciate you keeping this thread in mind though .

 

Can't get mad at people trying to save you money in the long run by avoiding the mistakes we've all made. I wish I had listened to all of the folks that said I should spend a couple extra bucks and get the 18G. To each his own..............

 

Im not mad, I am just stating that I have my mind set on a vf-34. For my application, it suits me well. Its all about response. Its still going to be another like 60 whp up from what I am running now. Thats a big upgrade if you ask me.

 

Hey Guys

Personnally the VF-30 that I had on my 2.0 was a huge upgrade over the td04 that came on the car stock. For a (street driven) car that was more than enough for the 2.0 in my opinion. I actually thought it was a little laggy if you wanted a little boost on the freeway in 5th gear. That turbo was also enough to max out a set of STI pinks on my stg 4 set up. I street drove this set up for over 5 years and was happy with it

I now have a 06 wrx wagon and am looking at getting pretty much the same size turbo but no larger than the 18g. This size of turbo is a blast to drive on the street, not to worried about drag racing or hi-speed freeway runs. It also does not take a whole bunch of supporting mods to compliment it properly on the 06. It is also one of the best bangs for the buck out there, hands down!

Good luck finding your Vf series turbo!
