Upgrade for power?

[tom.mattin]

I got a 2003 blobeye WRX 2l with decats, hks air filter, remapped. If I was to go 565cc injectors ans walbro fuel pump, could I upgrade turbo for a quick boost in power? If so, what one would be best for huge power on stock internals? Don't care about spool as I love that Hit and when you want boost you just learn to drive it like so. VF22 seems hard to come by and is silly money for what I've seen. Anyone got an idea how much a vf34 or so would give me on top of my standard td04?

 

Thank youuu

You will need a STI intercooler aswel for better gains. Sti intercooler, vf turbo, pink injectors, decat, induction kit will see over 300bhp.
