What gains would you guys expect?
first of all, 200hp @ wheels for a stock wrx is a bit high. Standard there 168kws (225hp) @ the fly.
Up pipe... whatever that is...
fuel pump and injectors
difference = not much
for a start, why change the injectors while running a standard turbo? I think they are a VF20.
Fuel pump might need to be changed if you run 17psi.
but you need to install a 3" exhaust and a front mount intercooler.
The standard top mount intercoolers on a wrx gets too much heat soak. Plus running over 12psi would cause some high intake temperatures. If they are high enough, it can cause engine pinging.
