And to the op, I run a vf-34 and have had no issues with it whatsoever thus far. It yields great power, and I got it for like 850 from gruppe-s. <3 it. Fast, strong power. 
VF-34 for president! He'll end the war! Solve world hunger! House the homeless!

Hmmm.... Well, seems convincing enough. One good thing about the cracks on the VF39s is that people seem to freak out about them and dump the things on eBay for $300.00 
You're really certain the crack is no big deal? How much boost would it hold before the crack becomes a fail (assuming a stock wastegate spring and no hotside mods [external wastegate])? What about ceramic coatings, which trap more heat in the hotside?

I can't really speak for ceramic coatings but I doubt it would really change things significantly.

EQ tuning out of all the vf series turbo's your saying the vf-34 would be these best for a 2.5l wrx?
And what do you know about the vf-43's? I know there upgraded waste gate holds off boost creep. Wouldn't that be better for somebody looking to tune their car more aggressivly?

The VF34, VF22, and VF43 are all great on the 2.5's. I have a VF43 on my own car. The power difference between these is insignificant and I have never seen any of them creep with a good downpipe.

wow, this thread sure got a whole lot of attention all of a sudden. guess im not the only one interested in the question at hand
im glad those of you running vf34's in here are happy with the results, its good to know i made the right decision.
here's a question: my dad's a proffesional welder, couldnt the crack in a vf39 be welded? i mean, that would solve it right? if someone was to pick up a 39 for a great deal, and for another 50 bucks get it welded and for another, say, 100 get it ported......then you've got yourself a great turbo for under 400 bucks right?
