cheapest way to get more horsepower

[Greenbread]

i have a 3's. i want more horsepower and torque. besides a cold air intake wut else can i do cheaply. Also how much performance am i gonna get out of a cai

 

[bluntman]

AEM dyno'ed a 2.3L before and after installing one of their CAI. The HP increased peaked at an extra 10hp, I would think that Injen created about the same amount.

Buy a CAI.

 

[sndsgood]

dump all your interior panels seats dash spare, etc etc etc. cost is free, downfall is u look ghetto

 

[bluntman]

Anything that will let the engine breathe better (CAI, header and exhaust) will increase your performance numbers.

[bluntman]

Well, the poster said "cheapest".

how do you take off the back seats? Ive tried before but couldnt figure it out.

I would suggest stepping down to a 15" wheels with a nice width on it. Reduce that rolling weight and height should help....

honestly nothing is really available yet. Give it some time.

horse power doesn't come cheap.... when you mod, do it right the first time and spend the money accordingly..and lots of it.....more money equals more mods, more mods equals more power, more power equals more speed, more speed equals another ******* ticket.....lol

My 2.3 lost alot of low end TQ from straight thru mufflers but being your exhaust is way difrent I can't say. Only way you really can tell is install a cat back and a month later remove it. but yeah cheapest way is weight redux and not using 89 or 91 octane fuel. CAI also works wonders. Anyone have cel problems for fuel trim levels? 2.3 was a rarety but some of us did get them from time to time comonly from going from a 50-75MPH freeway condition to a 3-5mph rush hour traffic in same drive cycle.

Do you mind elaborating on the "not using 89 or 91 octane fuel"

Thanks

I think he means keep using 87 as the manual states as you will not gain any performance until flashers come out to reprogram the ECU for the high octane. In other words it is just a waste of money to put 89 or 91 octane in an US Mazda3!

alot of people still beleve their non JDM(U.S./canada spec cars) need 89 and 91 octane cause of friends and shell with their V-Power promotions.

*edit* that 2 times we agree!

You can use 89 for better gas milage but you wont pick up any power from it.

e89 was used only in V6 with intakes and those 3i 3s and 6i pinging due to cold reigon they were in...car will not recignize (gainn ground pounding HP) over 87 unless you start touching fuel management, doing some FI, spark(ignition systems) or get ahold of a jdm pcm and be test goat for us spec.


Now the EVO ya got there...go as high an octane as ya want...That car will love you for it! (cool)

I'm pretty sure you will not get better gas milage from running 89. If it did I'm sure it would have been listed on the sticker with the higher MPG. Some people do buy cars by that number.

New Tuner/ NewMazda3s---HELP

Guys, 1st off this place is great. Exactly what I was looking for. Anyway, I need some help/opinions/suggestions. Been saving up some $$$ and I'm ready to start on my 3. So lets see what everyone thinks...
1-CAI---Injen vs. AEM, which & why?---PS, is this something someone w/ very limited knowledge about engines can do??

2-Catbak---Borla-thumbs up/down...other suggests?--same PS as CAI

3-strut bars---can anyone tell me where to find one for a 3??????

4-Perf. Chip---ANY INFO would be useful

5-S.PLugs & Wires---do these really do ANYTHING?

6-Body---All I can find is the basic rear wings, can anyone shed some light(and I'm not really sold on the cf hood thing thats was posted on this site yet, GREAT idea though-wouldnt mind seeing some more group discounts!)

What other suggests besides whats on these posts/threads? Not looking into stripping my car down just yet...too new for that!

PS-my ride is a 3s 5-door 2.3L, 5-spd!


THANKS TO EVERYONE FOR ALL YOUR HELP, VERY MUCH APPRECIATED
