Okay here is what I plan to do with my '03 Sub.

Vishnu Stage 2 which includes:
ECU Reflash
VF 34 Turbo
STI Injectors and Fuel Rail
Turbo Back muffler
Underdrive Pulley

Im also thinking of getting the XEDE add-on, I like the XEDE because you can change the MAPS . I want to upgrade the IC but not forsure if I want FMIC or a TMIC. I want a BOV but mostly for the sound, is it true that they can damage the engine? A turbo timer but not forsure what brand. Suspension is a must but i'm clueless there also. Please let me know what you guys think and fill in the gaps with what you guys think goes best with the setup. Thanks in advance.:banana:

 

If you are dealing w/ Vishnu at the same time i would get the JIC magic FLA-2's that they offer, the spring rates are different from the ones you get from JIC (Vishnus is made for WRX's)

If you are getting a Blow Off valve you have the PSI to make it work right, so i would get a GFB 50/50 , or a Forge blow off valve.

read this to make your decision on 50/50 or fully atmosperic or plumb back...

You don;t really need a turbo timer, unless you are at the track poundin the $hit out of you car...but I got suckered into getting one, i got an Apex-i tt and it works great.

 

I always vote for the top mount, unless you're pretty much only building a drag car. But if that were the case, you'd be getting a bigger turbo than a VF34.

Buy a BOV if you like the sound. Won't hurt anything, just makes the turbo re-spool slower whenever you lift the throttle under boost.

As for suspension, the Vishnu JICs are top notch. Great spring rates, make the car handle on rails without being too bouncy or jarring on the street. But that's a matter for the suspension forum.
