Modding my 2005 wrx 2.0 turbo and the mods I am getting are sti pink injectors , walbro 255LPH fuel pump , TD05 16g turbo , 3" 100 CPI fast flow cat , 2ND cat removed , 3" centre section , prodrive back box , bailey dump valve , pipercross panel filter and a ecu remap and hoping for around 320-350bhp..........Will this be enough mods for that kind of power or is there anything else you would recommend ?

 

That's in the ballpark, yes.

The 100cell cat is a little less freer-flowing than a decat but you should get 320+ (I'm assuming the WRX's TMIC is okay for that bhp?)...

 

ide suggest a STi tmic too mate, not 100% that ide go for the bailey valve either,but all in all with the tmic im sure you will see 320bhp. have you concidered the vf34 turbo? could pick one up for less than the 16g td05 (i think) and still get the same results

 

Yeah, set your 'goal' on 320 (should make that) and anything over is a bonus...

 

I'd add a decat uppipe to that list, helps the turbo to hold boost at the top end. Powerstation do an upgrade for the WRX to around 320bhp with the standard intercooler so it will be ok, but if you can get an STi or front mount

 

you'll be very lucky to get 320 mark on them mods, id add full decat and bigger tmic, for near 350 you will want an 18g

 

Forget the bailey DV and either buy a decent one (ie a forge) or stick with the factory one. The WRX TMIC should be good for about 350bhp, but an upgrade can see a cooler charge temp and a mate has seen his car make 10bhp more with an STI cooler over the WRX one with similar mods. The TD05 is rumoured to be stronger than the VF turbos, but the VF will spool up quicker and cost less.

Get a decat up-pipe and fit a green or K&N panel filter rather than a foam one. That, with your other mods, will see you get to about 320-330 with a good mapper. Any more and you'll need an 18G but that, with the right mods such as a FMIC and ported headers, could see you in the 380bhp region
