hello, im currently in the process of of modifying my MY01 WRX. i have the following mods cobra sports cat and 2.5'' cat back, do-luck panel filter, prosport 3 port boost solenoid and an sti up pipe. is there anything else anyone can think of before i get it mapped ? might go for a walbro 255, is it a stright swap or will i need a fuel pressure regulator ? thanks !!

 

Walbro Fuel pump will be good addition and highly recommended,because your Fuel pump is little bit old..
Fuel pressure regulator you are don't need.

thanks for the reply jura ! have you got any idea what kind of power i can expect after the remap with these mods ?

 

With remap you should have 270-280bhp,if you want more you must buy bigger turbo as VF34,VF30 or VF35(from £250-£450) and STi pink injectors (£120-£160) and with these mods i would say 330-350bhp
