What should oil pressure be in a Subaru WRX?
I don’t know about Subaru engines specifically, but most seem to run anywhere from 40-100 when cold, 15-40 when warm and idling and rise steadily as engine speed/load increases. That’s pretty general, but not a terrible rule. 85-90 seems quite high once warm.
Why does my Subaru Impreza air conditioner ice over?
2002 to 2003 Subaru Impreza, ( all models and trim levels) has an issue where the Evap core can ice over as a result of a design issue to the system, Subaru has issued a service bulletin about it. The fix is a new thermosensor (which is located in the Evap core).
What makes up the air conditioning system in a Subaru?
Typical Subaru Air conditioning Problems explained. The Air conditioning (AC) system in your Subaru is made up of the following. A compressor, Condenser, Evaporative (Evap) core, Expansion valve, receiver dryer, hoses and lines, thermo sensor and the controls.
Is it normal to lose R134a in air conditioning?
Adding to this is that it is normal to lose about 2 ounces of R134a out of an automotive system every year with no real leaks. So on the one hand the system could just be low enough to not function correctly after 4 years with no real problems or it can be low as a result of a leak. I wanted to point out some of the current issues we see.
What should the boost be on a WRX engine?
The lower the boost, the safer the setup (given all else is equal). As a general rule, 18psi (on 93 octane) is the boost at which the compression ratio of a stock wrx engine is pushed close to its limits. After this or even at 18psi on 93 octane, the timing will have to be retarded a bunch to avoid detonation.
Why does my WRX turbo keep going up?
With the exhaust gasses continuing to increase, the turbo speeds up and pushes more air into the intake side creating more and more pressure. If the pressure continues to increase and the wheel doesn’t slow down, many different parts of the engine/turbo can be broken (from over boosting/detonating and whatever).
What’s the stock horsepower of a Subaru WRX?
The stock intake (minus the resonator, See Exhaust for diagram) is capable of 325 hp. Intakes simply lean your car out (More Air Less Fuel) to gain power and can seriously hurt your engine and turbo if installed before engine management and injector upgrades. If you want to keep your car under warranty I would not recommend tuning at all.
