yo guys, i have an Impreza turbo wagon 98 (GC8?)

im looking at maybe gettin some decent hoses to get stuff flowing better but dunno what to get or how much to spend

at the moment its all standara nothing has been changed but within the next year it will have:

dawes device
Fuel pump and pressure regulator
Knocklink and boost gauge
STI intercooler, and fit a scoop splitter kit?? (not too sure)
ECU Re-map (Apexi power fc?)


any help much appreciated and if any one got any better mods (keeping standard turbo for now) to gain more power then keep em coming

Cheers

Stig
