i am about to get a walbro 225 fitted soon.
will i have to get a new fuel regulater like the fse one or will the standerd subaru one be up for the job. or will it just blow the seals or some think ?

 

I've just fitted one to my STI V5 and was going to also fit a Fuel Reg ready for mapping in Jan.
However, even though I'm aiming for about 340 BHP with other mods, I was advised by Bob Rawle that the standard Reg would be more than up to the job at these power levels.
So I would save your money and maybe put it towards another mod

 

tar for the info mate i will see how it goes then when the pump terns up. im not after mega bhp just want a tad more fule for the mods i have now on the car.
