2002 WRX Not sure what I have

[subywrex05]

Just bought my 02' Wrx in June from a dealer. Trying to figure out what I have as far as mods and whats been done to the car.
Ive looked at enough pictures and read enough of the forums to get a general idea of whats under the hood of my wrex but somethings
under there seem questionable from the weathering, missing heatshields and grease stains etc. Just asking for a "Wheres Waldo?" type of advice as to what you might see with the posted pictures.
Perrin uppipe and Im pretty sure the headers are stock. Looks like an aftermarket downpipe with a full HKS "hi-power" turbo-back exhaust.
AEM, CAI and I think thats it

stock collectors and cross pipe (aka headers).

Turbo I can't tell... All I can say is that the turbine housing is small, the oil line is stock, and so more than likely it's a stock turbo. But it's not 100% without seeing what it says on the side of the compressor housing.

Looks like an HKS flat-flanged downpipe as well.

The oil stain by the coil pack in front of the upipe in the second picture.... Is that from the turbo because i dont have an Oil catch? Ive cleaned the engine with degreaser but thats the only area that keeps getting the same oil drip/stain coming down from the intercooler or turbo not sure what it is. I havent had a compression test yet and theres a smell of unburnt fuel/exhaust, is that just the norm with the full exhuast or is there maybe a blown gasket somewhere around the bov/bpv?

edit: also the stain on the left side/top of the transmission.

I have no idea. It's hard to say without looking at it in person..

I got an '03 and have the same problem. I'm going to upload it like this, but with more pictures and details.

Could be a number of things...doubt it has to do with not having a catch can cause most people don't. Hell, it could be a result of sloppy oil change techs. Smelling rich could be a result of a catless exhaust system...or possibility that you aren't tuned.

[subywrex05]

I change the oil and like I said I've decreased the engine couple different times. The exhaust is catless so I guess that's the reason I'm smelling rich and I'm not tuned.
