Hi. for the past few days i've been thinking of going about different routes to make my wrx faster. really i wanted to reach a 400bhp mark. becuase of the high costs i decided to leave it for a while. am looking for around 310bhp on my wrx. what is the best way to achieve this. i would love to keep the cost down if possible. at the mo i have a FMIC, stainless steel exhaust with decats and boost running at 1.1bar. what could i do to get to 310bhp. is there anyone on here with a early classic wrx with the same mods as mine. what are your current bhp figures at. thanks for any input guys.

mickywrx has one running 330 bhp but i wouldn't go his route

Remappable ecu or remappable daughterboard and 440 injectors

£500 for the daughter board and you can pick up 440cc injectors 2nd hand and you will need Carl Davey, specialist Subaru Impreza parts supply to get them to fit

could my ecu be used as a remappable one or do i have to get one of those hks trendy thingys . i was planning on geting a walbro fuel pump and 440 injectors. what could be done to the ecu to run that much power. cheers myblackwrx

Your ecu isn't remappable as such but requires this Enduring Solutions Limited do the remappable daughterboard have a quick look on their site for what it can do.
Fuel pump is always a good idea as they are about £80 possibly a fuel pressure regulator about £200 unfortunately but the one on your car may is quite old and if you can afford it change it

does that ecu chip include mapping at £295. cheers

Unforunately not but it is the cheapest remappable option as far as i know(best thing imo is that it keeps the OE diagnostics)
