What size are 04wrx injectors, and what max bhp can you get out of them

thanks

 

i was just about to post the exact same thread

 

lol same,
Im currently sitting at 286 bhp on a wrx after being remapped and wondering whats the max ill get out my turbo through a remap?

 

judging by your other post yur switching to a vf35 turbo, you'll need to uprate the injectors and you'll need to uprate the fuel pump and then get it remapped.

 

What injectors will i be needing, and what sort of power would i be looking at will full decate and panel filter as well

thanks

 

The version 8 WRX has 380cc injectors, my 03 was making 332bhp/311llb/ft but the injectors were maxing at 106% duty cycle. They should run at no more than 80-85%. I fitted used STI pinks 550cc and the cycle issue is resolved and the car is making 340bhp 314lbs/ft. It's had quite a bit done to it by the way.

 

550's

106%? So does that mean they were supplying more fuel than they should?

think it refers to the time there open for

 

I dont get it?

so how can it be open for any longer than 100% ?

think its to do with the piston cycle or some or certain section of it. not real that up on the specifics
