Maximum whp and trq on N/A MZ3 ?

[Simon99]

Hi guys Sorry if that as already been asked, but I couldnt find it ... If I were to put all bolts and basically all possible upgrades without turboing or switching to a speed, what could I get out of my 2.3 Hatchback ? Is 200 whp possible ? Thanks alot

Short story: no.

Long story: With basic bolt-on mods, you might get UP TO ~20HP. Keep in mind that the MZ3 is ~130WHP stock. That being said, more extreme N/A mods (ie cams, stroker, etc etc) will yield higher gains.

[Ozil]

yeah, not much you can do to n/a mazda3 unfortunately...

[Jackal]

As they said no. Get the big three: cbe, headers, and intake and you'll see some gains in performance and a better sound. It's still a pretty peppy car that's responsive and fun to drive.

There is a tuned gen 2 sedan that's been piggyback tuned and he got an added 10 hp to his 2.5L engine. He's close to 180hp. Check out member's ride "Kiyomi".

They aren't stock 130, my 2.0 is 148 hp

148hp/135 hp torque

They're discussing wheel horsepower versus crank.

A 200 whp NA mazda 3 is a big ask considering that'd be about 235 @ the crank.

Cosworth makes some race ready engines that run the same block (and same head I believe) right out of the box. It's actually a duratec motor for the focus which is essentially the same as a Mazda 3 but the cams are different (Mazda's are variable on the exhaust I believe). It's a great thought, and I'm sure with some new cams and pistons you'd see some great results but with the money you'd spend, a bolt on turbo kit would be much more worth you time and money.

isn't that the brake horsepower? hes talking wheel horsepower.

Here's another thread on whp:

20hp to the wheel is very attainable....i can attest to that with just bolt on's....the big 3 I/H/E gives you that

Thanks to all the replies I guess I'll start with these, and set my goal at around 160-170 whp with more in-depth mods after that Thank you very much !

The answer to your question is based on another question, what's your budget?

You can probably get somewhere around 275whp fully NA if you are ready to spend the money.

Budget ? Around 3K

Not even in the same ball park

Sadly no, maybe around $30,000.

Cosworth prepped engine and a Haltech or Motec standalone would be what you would need that that point.


The biggest issue with the 3 right now is tuning. The parts have been out for a long time. The lack of support regarding tuning comes from the fact that there is a Mazdaspeed3. People who want a fast 3 buy the Speed. So the aftermarket puts the effort into the Speed. There are other advantages to the turbo as well since you typically get a lot more out of it with doing a lot less. If you spend $3000 on engine parts for your 3 you may barely hit 200whp. You spend $3000 in a Speed3 and you are looking somewhere at an extra 50whp. I would really love to see the NA 3's come into their own which is why I helped Justin with the tuner. If everything works out well with it you may be able to achieve your goals while spending a lot less.

[Simon99]

So I guess headers, exhaust and intake is my only real option to see and feel decent powergains ..

[Impressive]

If you come up with a couple extra grand you could boost your 3 and see more significant power gains...plus you'd be part of a club with only a few local members (boosted MZ3s)

[Chris222]

Well, there's always other options. You could put nitrous on it but it's not cheap, and at that price range, I'd just go FI. You could also put a supercharger on it, but it's at the cost of a turbo kit. Another route would be, to get I/H/E then buy a good METH kit with a fail safe device. Then find a piggyback to use like the Haltech FX10 or the PCS XFC and have someone do a custom tune for you with the METH that will get installed. This is the route that I'm seriously considering.

[zzz3]

get 30 shot bruh. stock internals can handle it.

[silverstarmazda]

a gajillion to the back bitches. isnt nos outlawed on street legal cars? plus, where u gonna refill it?

[Chris222]

hahahaha I wasn't telling him to put nitrous on his 3. I was simply putting the options on the table. As far as i know, nitrous isn't allowed in a street car. But that hasn't stopped people. Again, i'm not suggesting that you do this. There's also light weight pullies that you can buy. Look up SR Motorsports. They say that it gives you 8-11hp but who knows. In my opinion, just do suspension mods or if you do engine mods, just do I/H/E. You'll be a lot happier. The 3 doesn't have a good aftermarket for it. The speed on the other hand does. The 3 is an econobox made to compete with the civic, not a power beast. I've done I/H/E hypertech tune, and a godspeed intake manifold. Now, where i'm sitting, there isn't much more I can do without tearing open the block. I estimate that I'm sitting at 150whp. That's not a whole lot. Would i do it again, ya probably, the sound it makes at redline is so full filling. My goal has been 200hp to the crank. I'll get there, but it won't be cost effective. 200whp is possible by going high compression, cams, intake manifold etc. But 200hp to the crank is much more feasible. Good luck

Nitrous is completely legal on a street car, but not legal for use on the streets. That is to say, you can drive around with a nitrous kit installed on your car, but cannot use it on the streets and the bottle MUST be disconnected from the lines, otherwise there are huge fines involved.

Nitrous, turbo, supercharging...you're going to spend way more money than it's worth to not gain a whole lot without a full engine build with the proper components/internals. Besides...I wouldn't want to use the crappy plastic intake manifold in a boosted setup...that's just asking for trouble.

balance shaft delete is also something we can do. its cheap ($35 last time i saw) and its pretty straight forward to do. basically lowering rotational mass of any spinning item on the car will gain a bit of performance acceleration wise. i always say your not making power unless you pay BIG money. and if you dont, you might as well free up power from what the car parts take from the engine.

i'm pretty sure if the engine has no crankshaft, the car's not going anywhere.

whoops, i meant balance shaft delete
