Your motor should be a EJ205 which will make around 160kW of power at 5.6k rpm and have around 292Nm of torque at 3.6k rpm. It's a boxer engine which surely you have looked at your engine bay and seen the engine sits the opposite way to a SR20DET or RB25/20DET, it's same as a Porsche.
Just do basic mods to it like a
TBE and cooler if you want at least until you can drive it! Suspension mods to these cars are great if you set it up properly also.
Use the search and think about what you write before you post or call the fire bregade because you will get flamed
Happy WRX'n!
