Hello everyone.
I have a Impreza WRX STI 2003 ej207 2.0
Car have 22.000 kilometers.
Because I dont want to open the engine internals for more power, I want the best safe option to push the engine to the limit for more hp.
330 to 350 I believe is enough for enjoy the car if possible to reach these safe.
What is the most safe hp for this motor?
The car have exhaust system from middle to back, hks blowoff and green filter.
I plan to buy:
1) Downpipe (think for invidia)
2) Walbro fuel pump 255
3) a good ECU remap (what you suggested?)
4) for these hp I don’t know if need air intake, I think about injen cold air.
Give me you lights for more details or other set up..
