Turbo Info Needed

Im wanting to upgrade my stock turbo on my 04 WRX to a VF34, and im also running Cobb AP. The Cobb map calls for the stock intercooler with this turbo, so would it hurt or affect anything if i ran this turbo, the map for it, but with an Sti intercooler instead of my stock intercooler? Also, is there any other parts ill need besides my AP, and fuel system to run this turbo or with my stock wastegate, etc. be ok?

You should get (in addition to stage 2), bigger TMIC, 650cc injectors, and walboro 255 fuel pump. Be gentle on your transmission also.

Ok well im running the stage 2 right now, so id need say a JDM Sti TMIC, Walbro fuel pump, and bigger injectors. The map says 2 run the Sti pink injectors, but theyre only rated for 565 cc.

Garage
pinks are fine for a VF-34

If you're running somebody else's map, make damn sure you have the same fuel setup as the map says (IE pinks if it says pinks)

Yeah 565cc are fine, I just think a little extra room for an upgrade is always a good idea. But if the map says pinks, then pinks it is.

You dont need a JDM STI I/C, just an STI I/C would do you fine. But if you are running Cobbs OTS map and have what is in their map notes you will be fine. But if you change things a little, say injectors or a bigge TMIC you would probably be fine also, just wont get the gains from them.
