The reason I am creating this thread is to spread information regarding the de5fs, to find other enthusiast of this chasse and to hopefully learn more since gathering information about anything regarding the Mazda 2 is not easy.

I have owned my car for around 2 years and have covered around 20k km. Most of those km have been very hard driving on windy roads. The car has for the most part giving me 0 issue, what I have replaced due to breaking are top engine mounts (still had original one and I blew it) and suspension (had the front left strut leaking) which where both mostly a result of my heavy driving. The car currently sits at 100k km and even after my driving style it still burns not a single drop of oil.

Currently I am running the stock tune so around 111hp and I have yet to have any issues with the gearbox, and I don't go easy on it.

These are some questions I have about this chasse that i have not been able to find any info:
1. How much power can the stock transmission handle?
2. How much power can the car handle, from the little information I found someone said at 160 crank hp a connecting road breaks
3. Has anyone fit a fiesta st rear subframe on the DE, this is to have rear disc breaks
4. Has anyone ever put ITB's on the ZY-VE

I ask these questions just out of curiosity as I don't plan to push more power than it has as I don't see a point. In the future I would like to possible play around with the engine as just a passion project since it's such a unknown platform that it would be interesting, but currently I am just a collage student and spending so much money on a mazda 2 is stupid.

I absolutely love this car and it has exceeded my expectations countless times. It drives great and is extremely fun driving it on the limit. It was a great first car to learn all the basics of racing in but now I am looking for a car that can take me to the next step. I wont sell my mazda 2, I love it to much.

If you have a mazda 2 DE and drive it hard I would love to hear your opinion on it as sadly I have yet to meet a mazda 2 owner that is a driving enthusiast.

Any questions regarding the DE you can say here and I will try to reply as I have done a large amount of research on everything regarding this chasse.

The three door DE is so nice looking; it's a shame we never saw these in the US.

The different transmission ratios are interesting. Your 5-speed gearing matches the US version (we only got the 1.5 engine), only the final drive ratio is different. That would be a sweet upgrade if I ever opened up the transmission to just swap the final drive to the 4.1.

I don't think rear disc upgrade is worthwhile. I know drums aren't sexy, but there's not a ton of weight overall, and being front drive, more of the weight is up front anyway. I've read of folks running in B-spec racing class, and I don't remember anyone complaining about being limited by stock rear braking power. Plenty of pad upgrades available for the front, and as with any car, make sure you have fresh, quality brake fluid.

Good to see legit enthusiasm on a little hot hatch that may not have a lot of power but man are they fun to try to drive fast.

Good luck with the project.
Look forward to seeing more.

I should have read more closely before my previous reply, as it looks like you've already made upgrades to the front braking with a higher performance pad compound. You mention that yours came with bigger front brakes; how big are the rotors? The US versions have a 258mm front rotor.

The Fiesta ST has a different hub drilling, it's not 4x100. You'd have to do something to sort that out if you made the swap. I hear the ST rear beam is stiffer, so that could be a plus.

Have you added a rear sway bar or beam stiffener to your current setup?

if the vehicle has an open differential, changing it to an LSD would be worthwhile.

Regarding my break rotor size it is 258mm, where I am from most are 1.3 and come with 239mm rotors. I have just ordered project μ rear breaks shoes from japan because I needed to buy replacement pads for the front so I got those aswell. I have heard a lot of good things about adding a sway bar on the back but at this state I am trying not to spend more money on the car because I already drive it really hard and it doesn't make sense to try and make it faster. Currently saving up for an Mrs (it's the 3rd gen mr2 in the US).

With the final drive I have it's very good, shifting at 6k rpm sets you at 4k rpm so you stay in the band of the variable value time and you stay in the shorter intake length path. That's one thing I forgot to mention, I don't know if it is on all models but with the intake manifold I have there is a servo that changes between a longer or shorter intake path to increase power or torque.

I know Cisco sell one for around 1000 euros but currently I don't see it making financial sense. I'm more looking at buying a better car so I can improve my driving skills.

Thanks for the support.

It was a great first car, learned all the techniques like trail breaking, left foot breaking, heel and toe and a bunch of other stuff.

My favourite part is that my car looks stock AF and since where I'm from they are all 1.3 and automatic no one knows the 1.5, so it even funnier when I pass some random on the street.

I'm surprised I'm getting any attention on this thread .

So I decided to share this vid of me and my friend just messing around, quite an old video where I had a slippery clutch and no NS2R on the fronts and stock suspension.
