Car looks awesome!

Looking forward to hearing if you notice any sort of difference once they are swapped out.

Thanks! One cap in the spare ECU is starting to leak a bit already, I did use it briefly last year so I know it should be good aside from that. I don't know exactly what circuits they're part of so I don't know what effect each one might have but at least I shouldn't have to worry about a failure at an inopportune time.

In both my original and spare ECU, I've had to replace both 10uF 50V caps. One I did just recently (on my spare actually) and the symptom from it was the CEL randomly flashing and slowly illuminating on and off. I recalled it being the same symptom as the first incident from when it happened on the original years ago, so that is why I suspected this as the issue. When it happened years ago I bought a qty of two off ebay for $2 not paying attention to what a qty was. . . which was actually ten per qty of one LOL. Good thing because it was nice to have some on hand :)

I'm not positive about this but what I gathered from searching about the 10uF 50V caps in the past was that they are for diagnostics. . which makes sense given that my CEL was doing random things and I wasn't able to pull a code.

That might explain why a couple of times I haven't seen the CEL on startup. I ordered the parts and they were delivered the next day, I found that pretty impressive since I placed the order later than I would've expected anyone to be sending out shipments and it had to cross an international border. So a big thumbs up to Digikey for getting me overnight parts from Minnesota. I always find it funny that stuff I'm in no rush to get shows up immediately, and stuff that I need urgently seems to get delayed.

Not the best pictures, but it was cold and I was trying to figure out the rough idle issue it developed while parked at the ski hill. Turned out a vacuum line came off so it was an easy fix. Also rear strut tower bars are higher inconvenient for getting skis inside.

Lately I've been trying to decide if I should take more of a loss to get the car sold, or bite the bullet and do a bit more work to it to make it exactly what I'd want it to be. There aren't many cars that would fulfill my requirements (AWD, manual trans, 4 doors, newer than 2000, Japanese, decent ground clearance, under $20k). I have a pretty substantial dislike of Subarus but an Impreza is one of the few vehicles that ticks all the boxes so I test drove a 2014 WRX and I was genuinely amazed at how bland it was to drive. I told my wife I would go for it if we really needed me to have a more family-friendly car, but I wouldn't get any enjoyment out of driving it. She told me to keep the Celica (I'm a lucky man).

The tl;dr is the car is still technically for sale, but someone has got to really want it and be willing to pay for it to get it away from me.

I've also noticed a lot of people looking at the car while driving, and today I had a guy asking me about it while getting gas. I generally don't care what people think about my car, but it's still pretty cool. I highly doubt that would happen driving a bone stock Subaru.

In other news I finally got a chance to give it a nice wash. Work will slowly be continuing on the car, I've already got a pretty long running list of plans in my phone and I'll be updating this thread as they happen.

I get this on occasion and although it's typically only from people who know what they're looking at, it's very rewarding to receive any compliment no matter how small. . . it sure makes all the hard work seem worth it :) I'm sure you (and others) could say the same.

I can't say I share the same thoughts on them. . One of my favorite cars and the only body style Impreza I really like is a two door first gen WRX STI. But I can definitely see where newer models could seem more cookie cut and bland due to technology and creature comforts.

I've only met two people who knew what it is, the guy at the gas station initially asked if it was a Supra. I'm always curious how many people are looking at it thinking it's just a Celica with a funny hood.

I don't mind the look of the first gen coupe or the third gen hatch, I would imagine the first gen is a more sporty car given that it's from the 90's, but if I was just going to get another 90's coupe I'd buy a 205. I would expect a base model of any gen to be pretty meh but I thought the WRX and STi were always pitched as sports cars with that silly engine providing a low center of gravity and stuff. I can rant for quite a while about why I dislike Subarus but I figured I should put aside my biases and give the third gen WRX a chance and see if it was fun enough to overcome my dislikes. In traffic it was hard to judge but when I took it out to some twisty backroads it felt like driving the colour beige. The low rpm power was nice but stuff like the steering feel disappointed me pretty badly, to the point where I caught myself driving below the speed limit on a deserted back road and understanding why people buy automatics.

Obviously that's just my opinion, and opinions are like buttholes (everyone's got one, and most of them stink), and I seem to have slightly unconventional ideas on what makes a car interesting. But I'd genuinely struggle to understand how anyone could consider driving one of those cars as fun. Maybe there are some mods that improve the feel of it but I would think you'd have to make pretty big changes to make it feel significantly different from how it feels out of the box.

Well now that I'm fairly set on keeping it, time to start getting the stuff I need to get the car exactly where I want it. After someone on Facebook posted up about ordering a bunch of ST205 intercooler plates (which are now sold out unfortunately) I ordered a few spare OEM parts from Amayama, and stumbled across these snow version decals:

Image

I have no idea what they were originally used for as I've never seen them before, and I don't know what exactly I'm going to do with them, but they seemed neat so I bought some.

Also going off the suggestions of a few posts on this forum and a couple others, I ordered a Vibrant Ultra Quiet resonator. I tried an insertable silencer which helped a little but it kept breaking and rattling around in the muffler which was even worse. I had zero objections from my wife about ordering this for the car haha.

I took an evening and replaced the capacitors in the spare ECU, start to finish it took around an hour but a good chuck of that was me finding tools and remembering how to remove soldered components. I'll swap that one into the car soon and then repeat the process with the original ECU.

Awesome, I look forward to hearing the results. Was this a repair or preventative maintenance for your spare? I ask because if it's repair work, I'm curious which caps and on which board failed? I have been keeping up with other's failed caps and it seems that it's almost always the 10uf50v caps. I have only replaced the failed pieces but I'm tempted to replace all as a PM.

A bit of both, I ran the ECU last winter and it worked fine but when I looked inside last fall I could see two of the caps were starting to leak. I don't recall exactly which ones but I can check, one was on the main board and the other was on the smaller board.

Awesome, it was two caps and on both the top and bottom board for me as well.
