Hello, this is a thread that I wanted to make for anyone having the same issues that I did. Hopefully this will help you and make things easier because I had to go through a lot different forums and just do it myself to figure out the issues I had with my car. It’ll be a long post. Also whoever wants to add to this post you’re more than welcome to. This is a great community with helpful and knowledgeable people.

So I’ll start with the alternator.
If you get an oem alternator from Subaru, you’re easily paying between $200-$350. I doubt you want to pay for that when there’s alternatives.
So after I did some research I found that the 2010 Subaru Forester has an alternator that will work for the bugeye model. I went to the junkyard where I live and paid $40. It works better, higher amps than the stock one on the wrx. Stock alternator has 75 amps and the 2010 forester has 90 amps.

So if you need a new alternator look at the 2nd gen(2003-2008) and 3rd gen(2009-2013) forester. Also this is another plus, if you’re able to find a forester that comes with the turbo engine, that alternator comes with a 110 amp! Also will work for the bugeye model.

Next the Evap system.
My car initially threw a code P0457, states a small leak (gas cap loose).
Which didn’t make sense at the time because I had gotten a new one. Also I started to smell fumes within the car which isn’t good. So I came on this forum and read through a ton of posts of people having the same issues. Everyone suggesting different things. From replacing purge solenoid, the charcoal canister, canister vent valve, a blue “T” connector that’s next to you manifold, and even your fuel system. After reading for a month and kind of looking at the parts in my car, I replaced the canister vent valve. The code still came up after I deleted it. At that point I didn’t want to dump money into parts that didn’t need to be replaced just because of what I read. So I took my car to good shop in town, they did a smoke test and apparently my whole system was a mess because whoever owned the car before me, when they did mods to the engine they messed with the Evap system. So I had 6 different hoses replaced and the code hasn’t came up since. Also my car is more fuel efficient now than before I would run through a whole tank in about 6-7 days max!! Now it’s probably been 5 days and I still have half a tank left.
So my suggestion to anyone is take it to your local shop and have them do a smoke test before you diagnose it yourself and change parts that you don’t need to. Save yourself money!
Hopefully this info helps anyone out and thank you for reading!

EVAP leaks are a pain. It's never a leak in one spot and they usually cascade after the first part is checked.
