Ok, so im planning out a build for my motor. Looking to fully build the bottom end, parts are harder to come by, so choices are obviously limited a little bit. But im curious to see anyones setups, andvice or literature anyone has to offer... my searches are comming up short..

also if anyone has any info on what would have to be changed if i was to do the 2.3L n/a swap ....


Thanks in advance for the help!
 
Mild:
Balance shaft delete kit (2.3l only) Short or cold air Intake Cat back exhaust Stage 1 clutch (manual) Lightweight flywheel (manual) Oil filter conversion (2.3l only) Stiffer rear engine mount Ground kit Lowering springs Strut bar Short shifter NGK plugs Decent brake pads (EBC, Hawk, etc.) Lightweight crankshaft pulley (You MUST tq to 80ft pds and then turn the nut an additional 90 degrees using a breaker bar)

Wild:
Stage 2 clutch Lightweight accessory pulleys Tq dampener Stiffer trans mount Valvebody upgrade (autotradgics only) A/F controller Intake mani Header Shocks Accelerator lag reducer (electronic throttlebody only) Launch controller

Extreme:
Oil sump Polished and rebalanced crank to desired rpm Forged rods and pistons Head gasket Valvetrain upgrade Cam and cam gears Standalone EMU Re-enforced trans gears (manual) Tq converter (auto) Spec clutch Performance radiator and fans Turbo kit Supercharger (eventually...maybe) Stiffer drivers side engine mount Coilovers Cable throttle body conversion High output Injectors LSD

Basic build w/info
Intake: Any one will do, none differ from the other except size and price, top of the ine is K&N and F2 but all will give the same amount of gains, which ever one you use make sure its black, this is to ensure you get the best heat dissipation possible to keep the air charge cooler Exhaust: If you decide to do just a custom cat back the recommended pipe outside diameter is 2.5in anything bigger you will loose back-pressure therefore losing ow end tq. If you can find a mazdaspeed 3 exhaust its a direct fit as far as the bends go, its just a tag longer though. If you want to get a header as well you can go the cheap route and get the obx setup but that is a 4-1 setup which is mostly beneficial to higher hp applications the other option is vibrant 4-2-1 mostly beneficial to higher hp applications the other option is vibrant 4-2-1 the price is extremely high but its a better setup Motor: If your feel good about this then i recommend doing the crankshaft balance shaft delete mod for the 2.3l. 4cyl are naturally unbalanced, all the balancer is also keeping down vibrations....its just a comfort thing, some say it promotes engine longevity but thats a myth, cheap and easy.

Lightweight crankshaft pulley, the only thing that i suggest is that you get someone who is 100% on how to do this, if done incorrectly, stripped bolts holes, wrong timing among other things could result in one bad day. If you didnt know a lightened pulley will dramatically increase the rate engine rpms ncreases. Motor mounts and/or engine tq dampener, if your complaining about too much wheel hop then you must be beating on the car kinda hard, a GREAT way to reduce that is stiffer motor mounts, downside? depending on durameter rating extreme vibrations that will diminish after a month or two Trans Short shifter, lightened flywheel, staged clutch are the norm. Careful when purchasing a short shifter even though the throws may be shorter thats not purchasing a short shifter even though the throws may be shorter thats not always the best. You can never go wrong with a lightened flywheel. When it comes to picking a staged clutch make sure its a stage 1 for a mostly stock comes to picking a staged clutch make sure its a stage 1 for a mostly stock build, otherwise severely reduced trans life may occur or premature flywheel glazing as well as a short lived clutch. build, otherwise severely reduced trans life may occur or premature flywhee build, otherwise severely reduced trans life may occur or premature flywhee glazing as well as a short lived clutch Suspension: A common mistake made is people who think lower is better or just getting springs and keeping the stock shocks/struts is a good enough to make it springs and keeping the stock shocks/struts is a good enough to make it handle better, well there wrong, if your looking for a better handling ride w/o getting coilovers and wanting a nice ride for everyday driving and spring and shock combo is a must. A strut tower brace along with front and rear anti-roll bars will also noticeably improve your 3's handling capabilities. bars will also noticeably improve your 3's handling capabilities.

Braking:
People also tend to believe that bigger brakes are better, well that may be somewhat true its highly unnecessary to spend that kind of money if your just daily driving your 3 or even if your in autoX, road race, or mt.climbs, but what you DO want is better brake pads and your NOT gonna find them at advanced autozone, or pepboys....nor your dealer .*Please keep in mind that above list is not going to add a major difference in power, what will be felt is a considerable amount of response.

There's a few repeats n typos cause I copied n pasted from my phone. But here's some info on a few building techniques...
 
Thanks!

Im looking more for specfic brands, if they bored the motor..etc..

Surly someone has built the 2.0
 
heh what urdaily3 posted is my thread on the other forum that im a mod on, tbh its a very basic concept for what to get when you start modding, if he had looked a little further he would also of found my basic turbo build.

c.smock i pretty much have a build out list for an insane 2.0l, if you have any questions i can kinda help.
 
definantly interested! I wanna go all motor for sure though... what setup ya got in mind? i like insane lol
 
well all motor is not the way to go if your looking for "insane" power, my best guess is a fully built all motor 3 would break 13's....thats it, the other problem with that is your going to spend more money going all motor than boosting it, the reason is there is no aftermarket cams available for the 3 w/o losing vvt, the cams or camshafts is where most of your power is gonna come from, if you boost it you really dont need to have the cams or camshafts (although would greatly help) and you would end up in the 12's or even 11's on a cheaper build than an all motor one. in short you have to go ALL OUT on a motor build...its not like a honda
 
Btw does anyone know where I can get a new or used 2.3 crankshaft??? I checked with the dealer and its a little pricey.
 
I've been wanting to stroke the engine.. up to 2.5l if i could. That would def bring up to the power I want and would make the car sound more beef. Don't know if into the turbocharging idea. At that point i'd rather a speed and in terms of vvt my 2.0 is a 2005 so i don't have that either way lol But yeah an insane all motor build would be really nice. Especially being able to feel it pull all through the rpm range =D

All mazda 3's have vvt, and ive already done the research on how to turn a 2l into a 2.5 (or atleast how mazda did it) but im not telling :D
 
im thinkin 2.0 bored .40 over with 12.5:1 compression pistons.... hmm...

12.5 comp means you cannot use pump gas anymore, .40 over is possible but i havent tore down the block to see if that would run into the water jackets.
 
12.5:1 i can still run 93 octane... if i went 14:1 then id have to run 103 or higher from what ive been reading...
 
did a little research a seems that you can run 12.5 on pump, but its highly recommended to get longer duration cams with it to reduce the chance of detonation, currently there is no aftermarket cams you can get unless you want to lose vvt, other than that you can send your stockers out to be reground
 
:O well if u know this little secret then what's the cost? i highly intend to do it once i start my courses in mechanics this fall. Also it's first time i hear of 04-05 2.0l having vvt, it doens't say it anywhere on my car
