I'm looking at upgrading the turbo on my 06 WRX. I'd rather get a reasonably VF34 off eBay or whatever, get someone to fit it, then drive carefully to the tuner to get it remapped. If I do that though, I'd want to get any necessary supporting mods fitted at the same time, so I'm only getting the map done at the tuner. Given the list of current mods below, can anyone suggest what other mods I'm likely to need? This will probably be my last upgrade for quite a while - I can't really justify stumping up for new internals and gearbox! - so no need to leave lots of headroom for future upgrades. I'm guessing I *may* need a new fuel pump; injectors; boost solenoid; spark plugs; fuel pressure regulator; but I don't want too get anything unnecessary. I'm currently on about 290bhp, looking for around 340.

Current mods:
Powerstation performance upgrade (3" milltek exhaust, pipercross panel filter, ecutek remap)
Process West top mount intercooler and shroud
Resonator-ectomy with GP moto elbow and zero/sports intake pipe
Zero/sports cool radiator
Powerstation stage 2 handling upgrade
Godspeed 335mm front disks and slotted rear disks

Cheers for any advice

Fuel pump and STI Injectors on top of what you have and a remap obviously Oh and some PFR7 plugs

Should see you with 340Bhp approx

 

Decat d/p or sports cat, 255 L/PH fuel pump, NGK PFR7B spark plugs and Samco TMIC piping.

 

Cheers guys, that saves me wasting a bit of cash
