Introduction/Ownership History

So back in 2017, I started looking for a fun, fuel sipping daily as my modified supercharged Xterra was getting 10mpg, but also aging and it's hard to fix or modify a vehicle you drive every day. The girlfriend's Avenger also wasn't doing well and needed some major work coming up to try to extend its life. I had a price in mind so that I could pay it off quick, and that the fuel savings would have the car essentially pay for itself. I also wanted to have it paid by the time I released from the army and went back to school in 2021, which was going to be a daily 110km round trip. I will not modify it, I said. Famous last words to be sure. What I wanted in my 2 was to have one under 100'000kms, with a manual, air conditioning and cruise control. After months of searching looking around at a few and making sure the girlfriend felt comfortable with learning stick on one, I jumped on a good deal. A 2011 with 73'000kms, even came with a remote starter and some winter tires near the end of the life, but enough top get me through its first. What I didn't know is what was a Yozora edition and how rare it was. It was however missing the (Miata) rims that it would have had from the factory and just had a set of steelies with hubcaps.



First thing was to replace the battery that was missing some CCA's to start when it was very cold. Come spring I found out the AC was not blowing cold. It had a leak in the condenser so I replaced it and got the system recharged. After a while, I grew frustrated with the classic AM/FM/CD radio. Not only with crappy phone holders and an AUX and charge cable in the way of the shifter, but also crappy Quebec radio. I installed an Android Auto Kenwood DDX-6509S radio, which really improved my daily pleasure of driving the car and made it fell much less antiquated. While I was at it I also installed a Black Friday special dash cam I had laying around for a few years that was supposed to do into the Xterra and also some heated seat pads from Amazon as the little 1.5 doesn't warm up quick when it's under -20*C out. It also does wonders for the back on long trips.

That summer I picked up some MX-3 5-spoke rims from a friend to replace the ugly steelies, with a tip of nostalgia.



While the radio did help improve sound quality, after some time it felt like it was missing in the SQ department. The next step I changed out the OEM speakers that use fridge magnets for some Focal speakers with a pair of tweeters. I also picked up a Bose spare-tire sub from a Mazda6 and along with a new 15" rimmed spare tire from a Miata to cover the low frequencies the Focals were missing.

Then the pandemic hit, the car sat for a few months and the rotors warped (as well at those in the girlfriend’s Avenger) so I took the time to upgrade the rotors to some PowerStop slotted and drilled rotors. I decided to take a page out of my MX-3 playbook and ordered from PBR ceramic pads, but this time round I couldn’t find a Canadian reseller and had to order them directly from them in the USA.

At this point, it has been a very pleasant daily, but this is where things go off-track. In 2021 AWR was doing a group buy for a passenger side motor mount. While their dog bone mount is well known to crisp up shifts and was on my to-mod list, the passenger mount group buy was missing a few people and likely be a one-off batch, and I just cannot let those get by. At the same time, I order up a DDM Works short shifter and bushings. To finish the combo, I ordered an MX-3 shift knock to get rid of the econobox-looking one that came with the car. The AWR mounts came in their softest 62-durometer bushings, and it did take a few months for them to settle down, they did have an unexpected, positive side effect. What I felt the 2 was missing was also what I had in my MX-3 was a strut tower bar. While it was always argued back then that it was useless but I swore by my pair of CorkSports and has dearly missed the front one until I could figure out a way to get it to clear the intake manifold of my KL-ZE swap. The same argument was said about the 2 and that it’s useless. I did look a bit, some being in heavy steel, others having issues clearing the brake booster in the left-hand drive cars. I also would believe it as the strut towers are much closer to the firewall compared to the MX-3. What the Passenger and Dog Bone passenger mounts did was give me the feeling I was looking for by reducing understeering and improving steering response. This is where the handling bug had bit.

For 2022, the 2’s suspension, especially in the rear, was showing its age and summer tires that came with the car didn’t have much meat left. I bought some Yokohama Advan Fleva V701 tires, which not only drastically improved grip over the cheap tires it came with, but also oddly, improved fuel economy, shaving about 0.5L/100KM from my average. Not long after I bought the last Bilstein B14 kit from RockAuto, install it that week, had it aligned the next day. She was suppose to get tie rods and an alignment but ended up getting a new steering rack to remove the play. The next day after we bought her to her first Autocross event. I haven’t done any since I was in my MX-3 back in 2007. This would also be the fist time the girlfriend would take a car on the track as she wasn’t a passenger but registered her as a 2nd driver. We had a blast and I can’t wait to go back.

Then to follow up, AWR then decided to come out with a new driver’s side motor mount, so I had to get in on that order as well. While I was waiting for that to come in, I got a brainwave. One thing that also bothers me with my 2 is the lag of the Drive-By-Wire system. Rev matching has to be deliberate and less natural, and on upshifts, I’ll power shift if I’m too quick with the pedals. I did read that you could get a tune to compensate, but I vaguely remembered someone using the throttle body from a 1.6L MZR. This had to come from overseas and found one from Poland. I waited to do the TB install at the same time as the AWR driver mount. With the new TB, the power s**** have greatly disappeared; rev-matching downshifts are can be done WAY more naturally. Low end was also significantly improved, allowing for 2nd gear rolling stops to the point where you could almost start it from a dead stop.

Since then I’ve been driving here and there but no real time to enjoy it as I’ve been hard into landscaping and using the truck (V8 Pathfinder) regularly for those duties. I’d love to head back to an autocross event before the end of the summer. Not too many other mods planned at the moment other then controlling a few rust spots, but I’m still contemplating getting a tune to further reduce DBW lag, raise redline a tag. You can feel the engine want to keep going above the hard 6300rpm redline. A cold air intake is tempting and so are some headers, but we’ll see as I get inspired with time.

Looks like you're having a lot of fun with your Mazda2! (y)

It would be great to know more about it...Is this going to be a build/project thread? 😁

Indeed. I really like it. It may be only 100hp, but keeps the skills in check and still a blast to drive.

At first I didn't think to bother as it was just a daily driver, but as I mod and use the car I figured I should have a place to document it and share my project and experiences.
 
So in 2023 was able to give the 2 some TLC. Seems to be a common-ish issue about water getting into the trunk area. It might be from the light wiring grommet, might be from the bumper mounting bolts, might be from the sheet metal seams, or everything. Still, the floor or the trunk wasn't doing well needed a replacement. I got the trunk floor from a friend's crashed 2 and the plan was to transplant it.

While I was there I wanted to add in some rear fog lights. After going through a winter storm I remembered how well they work for low-visibility daytime situations where the running lights aren't sufficient. The large majority of drivers don't seem to know that lights aren't just about seeing but being seen. Being a small car surrounded by larger trucks and SUV's this is for my safety. I realised after getting them in had that the EU fog lights can`t mount into an NA bumper, so I ordered one from the UK. It fits like stock but requires the extensions to be removed from the crash bar. Also while I was modiftying the crash bar I decided to add on a low profile trailer hitch.

The North American (Canadian) bumper, before its removal

First, was removing the bad section and using it as a template to cut out the new section.

It was a weird summer for rain, where it just came and went. There would be sun when I put my head in the trunk then eventually feel drops of rain of my lower back. The frustrating part was to lung the welder back into the garge, but the rain did help to show me where the water was coming in.

The rain didn't slow me down, it just allowed me to switch gears and work on modifying the crash bar.

The rear recovery hood was removed and grinded down. I'd made a mounting plate with captured bolts to add extra stregth to the hitch. I think an aftermarket hitch uses only the bumper bolts, but I like to go overkill.

The new floor got places, tacked and welded in.

I didn't like the grey lower section of the bumper so I masked it off and painted it using Krylon Fusion Gloss Black.

Once all said and done, the next thing was to go through every nook and cranny with seam sealer. Unfortunately I picked up the white tube of sealer so I went over and painted it over with a brush. However, it does snow where I sealed.

The trunk floor also some seam sealer, rubberized coating and finished with a grey paint.

20230806_090603.webp


I then made a new bolt to secure the (Miata) spare tire along with the Mazda6 Bose sub.

The underside got a coating of seam sealer, rubberized coating and black paint. I also made a bypass for that stupid low-lying the evap canister amd tucked it away.

For the wiring part is was pratty simple. First I had tested switch compability with a headlight-level switch for my RX-8 and then with some research, ordered a front fog switch for a 2001 626

I used a tap and had it fed from the fog light relay`s output, meaning the rear fogs will only work when the front are activated. I ran that line to the trunk along with a 12v power. The switch triggers a standard relay. The rear fogs will work with the brake lights in standard mode and when the switch is turned on they'll stay illuminated regardless of the brakes.

While doing wiring for the lights, I added a 4-pin trailer converter harness.

The front wiper arms also got some sanding and a fresh coat of paint

2024 the 2 didn't get much love in terms of work on it, not like I wanted to anyway. I was trying to get a rear disc conversion kit from Lapp Racing/Gold Coast Automotive but after an initial reply, they went silent. The fronts were done and I wanted to do it all at the same time. With that, I got a set of new OEM pads from a friend and went to joint him at the AutoX event he as working at. Weather was great and had a blast! I really love how it feels power and handling wise. It's not at all competitive in it's class, but I don't care. Too much fun!

2025 however is starting on the right foot. I deactivated the heated seats a few years as the drivers side pad has created a short and wanted to burn a hole in the seat. I ordered new pads a few months ago with the intent of doing them before winter. We had some slow time at work so I decided to do it there. I had figured the seat foam may need some TLC so I figured I'd have a go as refreshing those as well I cut out the bad sections and replaced it, using the original pieces as a template. What looked odd and didn't realize was how much they were compressed down and built it back look, using the opposing side as a reference. As per a YouTube video, I added some cloth to tie the repair together. I also added some extra padding and some lumbar, which I found was lacking on those long trips. The new heating pads were installed and everything went back together. I did also wrap up the seat and gave the rails a sanding and a fresh coat of paint. I left them to cure over the weekend and will reinstall it shortly. The plan is to check out the passenger seat as well to see if they need some work.

I do like using zip ties as I don't have the hog ring tool, but I find really facilitates working around the heated pad, isn't conductive and I can also adjust the tension on the cover and the foam.
