Hello, I want to increase the power of my mazda 3 Grand Turing engine 2.0L 153 HP, how can I upload a 50HP or 60HP, but he read in many forums that the skyactiv engines are somewhat complex, what do you advise? >:)

Thanks.

An SRI or cold air intake can add 5-8 hp at 4,800 rpm or so.

An axle back or cat back exhaust can add 15-30 hp or so.

Ummm.....no. Maybe on a dyno, hood open, fans on you might get a couple hp. Real world, driving in traffic, sucking in under hood air, the best you can hope for is no hp loss.

Wait, what? Which one?:laughing019::laughing001:
1-3 hp more like. Some mid pipe /resonator replacements actually cause power loss. Peak hp might be the same or a bit higher, but torque numbers are lower.

A tune might get you 30 hp, more if you use E85 or similar fuel. If you can find cams ($$$$$), 15 or 20 hp maybe. No headers that actually work are currently available. A forced induction kit, if you manage to find one (many more $$$$$$$$$$), can get you to about 250 hp. Anyhow, to get past 200hp you are looking at several thousand dollars at least.

Yes, I understand that putting a turbocharger for skyactiv engines is very, very complex, and there are few workshops that do that job, and the few that do, charge a fortune: c

NITROUS OXIDE. T here are 4 cylinder kits in use and yes they work great on D.I. engines. Been tested and currently used in late model 4 - 6 - 8 cyl. engines. Easy to do and the Sky engine can handle it.>:)
Just use as directed and don't get greedy ...then you blow your manifold...lol But seriously , yes it works.

I can tell you a 2.5 with intake and cat back loses on the bottom, gains on the top. A tune changes everything (93 octane, redline to 7k) and you need the bolt ons to get the most of it.

I’m seriously considering the NO2 for fun. It feels like it can take it.

Motor and trans mounts of course.

Catback, Intake, mounts, tune=new car
You won’t be disappointed. $2k

I'm thinking turbo isn't as hard as it seems reason being its been done follow the same blueprints as flying miata!
Not the same car, very little ECU support for the Mazda 3. You might be able to make some of the parts from that kit work on the transverse motor but getting it to run properly is going to be extremely difficult.

I dont think so, you can use the same mazda edit software that ovtune uses. Mostly gonna be fab work you can find the parts needed on ebay I found mock manifolds from the cx-9 I know this isn't saying much but I'll get it done. I ll have results just give me some time.

That's because you don't try the throttle controller, people who have tried that all have positive review on it
Ummm, no, lots of negative reviews in fact.
All it does is change the signal generated by the TPS to apply more throttle with less throttle pedal movement. Snake oil and gimmickry. You can get the same effect by just pushing the throttle pedal harder....:bash::bash: Save up a few more bucks, get the motor tuned properly and do the OVT throttle recalibration.

Again, what will a "throttle controller" do for power? Nothing at all. :eek:
