I own a classic impreza turbo 1999
Current mods are
-k&n panel
-decat full 3inch exhaust ,
- 440cc yellow injectors
- ecu map
- 8pot ksport big brake kit
My next mods are gojng to be sti top mount , walbro fuel pump, japspeed fuel pressure regulator after these mods what horsepower would I be expecting from my car ? I am then hoping to get a vf23 turbo and remap the car hoping this will take me to close to 350bhp any suggestions on other required mods I'm trying to do as much as possible buying parts from other cars to keep cost down a abit aim is still to et around 350 bhp thanks in advance everyone

I think the TD04L will run out of puff first around 280-290bhp. Apparently the 440's will only make 330ish and will be at their limit. To be safe I would get 550's.

Once you get to 350bhp be careful with the clutch and gearbox as both will be stretched. People do run 5 speeds with 350-400 and higher but it's a matter of time before they destroy themselves unless you are one of the few lucky ones.
