I would say it's an older WRX issue then, not a boxer engine thing.
Almost all built engines with forged pistons have a fair amount of it until things are warmed up too.

I'm with @Pkush. I always prime the fuel pump on whatever car I'm driving. Since living with the push start though the though has never crossed my mind... I'll do some tests today to see how to get it to work, but I think if we put the ignition to "run" and press again, the power goes off.
On another note, I've noticed my valve overlap doesn't always seem to "kick in" when starting it in cold. This normal?

Because the AC compressor saps precious power when it's running, which is annoying at idle, especially in a manual car where it raises the odds of stalling.
The AC compressor is not bringing any value when it's -20 out; might as well lay it off for the season. |

If your idle is stalling your car, you've got a problem that should be checked. The compressor doesn't kick in at that cold a temperature, there's a lower threshold that the full auto climate control system has, unless you manually have the AC switch on of course.

The "stalling issue" is that if you do a slightly sloppy take-up at the instant the AC compressor kicks on, it's often enough to stall the car. I rarely ever have that problem, thanks to decent skill, but with the compressor disconnected, I never do, because it's not possible. Since I'm a commuter in a city full of morons, I like the peace of mind of having a predictable idle. |

I don't get the "stalling issue" when trying to pull away. It's simply when sitting at idle that I notice the rpm's dip slightly when the compressor kicks over, and sometimes the idle will drop so low that it feels like the car will stall.
Didn't seem to be happening yesterday, however, and I was sat in the car for the better part of an hour having a coffee with a friend.

But what about when you want to get some humidity out of the car?

As far as the stalling issue if the rpms drop too low the compressor will disengage same as if you go full throttle with the air on the compressor will disengage. As for not bringing any value the freon inside the ac system has oil in it to help keep all the rubber seals on the inside of the system from drying out and leaking the only thing you are doing by disconnecting the ac compressor is raising the chances of having the air conditioning not work when you plug it back in. |

I completely understand the theory as to why it runs in defrost mode. Still, with it disconnected, I don't have to deal with annoying RPM dips (stalling aside) and I can still see out of my windshield just fine.
Remember folks, you're not obligated to make this "mod" if you don't want to. Ask your doctor if leaving your car the way it is is right for you. |

I wonder if there's a way to disable it for the FRS guys (BRZ Limited guys are probably out of luck due to auto climate control).
In my old Celica, I disabled the A/C mode for the defrosters only (for some reason, Toyota engineers figured drivers were too stupid to turn on the A/C themselves to defog windows). However, it was easy to just loosen the one wire that linked the two systems. I'd prefer to be able to turn on my A/C myself.... |
