Upgrading 07 wrx to sti turbo
so i was reading a turbo thread on nasioc, it says that for a vf43, 02-05 wrx's will need fuel upgrades. does that mean that 06-07's dont need fuel upgrades since they are all ready 2.5L?
if this is not true, what would i need to upgrade my 07 wrx to an sti turbo?
current mods: turbo xs TBE, Cobb AP v2

I also own the 2.5L engine on mine. From all the reading and research, I would change out the Top Mount Intercooler, maybe Walbro 255lph Fuel Pump. It really depends the turbo your upgrading to, just as 1sicwrx said. The stock fuel injectors on the 06-07 WRX has approximately 550cc stock injectors installed already.

I went VF39 a couple years ago. I did SSAC TMIC (larger top-mount, STI will work), Walbro FP, TUNE, and I think that was it...
After tuning the WGDCs for boost, I'd def. recommend a 3-port boost solenoid when tuning.
A 3-port BCS will drop your WGDC ~30% though, so I'd say bring it to your tuner and have it installed right before the tune. You really dont want to overboost!

I upgraded to a VF43, other things you'll need include a better TMIC (I got the STi one) and a tune via your Cobb AP.
If you get a VF39, yo ucan run the Cobb maps from their website. For something like the VF43, I went with an e-tune from Clark Turner. For $150 he sends you a base map and thus far I'm into a 2nd revision of the tune. You datalog on the AP and send him the logs for analysis/map tweaking.
The VF43 makes so much more usable power than the TD04, its not even funny. My mileage is still about 23mpg if not BETTER at times. And best of all, everything from the turbo up is factory hardware.

Did you do it yet?
I've got an 07 WRX TR with a downpipe, Borla Hush, MBC & a tune.
I'm having a VF39, STI TMIC, Walbro fuel pump, transmission/motor mounts and a tune installed next week.
Let me know how your VF43 worked out.
