Hi.
I have just bought a 2.5 wrx on a 56 plate, Somone has already fitted new back box pannel filter and dump valve.
I am getting a 3inch de cat exshaust and remap done shortly and hope to upgrade the turbo next year sometime. Should I be changing my fuel pump and injectors? & What turbo would make a good replacement?
Thanks

 

for your first map both fp and injectors ill be ok, you looking at about 290bhp.
For next stage you will need to upgrade both alond with a list of other parts.
Im just in the process this now and bought a td05 16g from andy f.
You can get that or vf34, 35 i believe or a td05 18g if your brave
