Hey guys,
Trying to decide on a new turbo for my 02' WRX. Should I go with either the VF22, VF23, or VF34. I know that the VF34 spools quicker then the other two but I heard it losses some top end. I wanna run around 17 psi as a daily drive and I want me car to be reliable. I heard the lag with the VF22 isn't bad. Let me know fellas and what kinda numbers can I expect with supporting mods and FMIC

i dunno about numbers but the turbo doesnt lose its breath on the top end like the stock turbo its fine
i boosted to 1.5 bar one time it holds its boost

Stock turbo can be boosted to 1.5 bar, but it is not efficient there at all. Just a bunch of hot air.
I would go with a 34. 22 is ok too, but not 23. 23 is too small.

a 34 is capable of slightly higher power output than a 23.
i have a 23 and am very pleased with it.

I drove my buddies wrx with a vf22 it really comes alive around 3500 and pulls hard
daily driven 18psi with a vf34 you will come on at 3000 but drop off sooner.

maybe I have a VF23 in my car then. I got it tuned yesterday and it made less peak power but it made more torque at lower rpms (that is what Shiv told me). I have the plots but no floppy drive to put it on my comp. If I get a hold of another PC I will post them.

I have a VF-34 that was ported and polished by Deadbolt Industries, and ceramic coated, it spooled quicker and made good power. From what I have seen and read VF-22 is just laggy and un-responsive. I have not heard much about the VF-23.
My vote is definatly for the VF-34. Port polish and ceramic coat and you will be good as gold !

the 22 can make an honest 400chp though. no other ihi has the compressor that can efficiently go >20psi. the #1 reason to buy a 22 though has got to be the price per hp.

do you guys have the site for the place that ports and polish the vf34?

http://www.deadboltspeed.com/ is the place I got mine done. I had the exhaust side ported and polished, intake ported and polished and both sides ceramic coated. Shiv from Vishnu said that my spool time was down and power was up a little bit from the normal VF-34 setup. Definatly get the ceramic coating due to the fact that subaru's have their turbo side right under the intercooler, so as much heat resistance you can get is great.
