NA Power Stage 1: Basic Modifications

So I didn't even know about this and I started this "stage 1" thing.. lol, I have the K&N, maybe that's why it sounds deeper and has a little more throttle response?

You're always on M3F and you didn't know about this? It's a frickin' sticky on the modification's section! see what happens when you spend too much time taking pics of 3? :p


... unless you're different from M3F's BoostThat3...
 
I am new to this forum, and definitely new to modifying cars. I don't even have a 3 yet, but it is number 1 on the list when I return to the U.S. this year and buy. I have a question about the grounding. It seems interesting and easy, and I guess it explains the lights in the engine bays of all those Fast and Furious cars.

Step one is grounding the throttle body, and step two is installing the voltage stabilizer, which you said you attached to the fuel rail, left strut tower, throttle body. Do you then have two grounds on the TB, or when you installed the stabilizer, did you remove the previously installed direct ground from the TB?


Pardon the n00b questions, and thanks for the information and pics. This will really help me when I get my 3. I am eagerly awaiting Stage 2.

The voltage stabilizer actually covers the TB grounding. A simple 10g wire from the TB to the negative battery terminal will hold you until you get the funds fo the stabilizer. The Buddy Club kit seems to be a hit with the 3 crowd. There seems to be a new owner almost every other week- and they have good reviews.

Here's stage 2 (tons of dynos). It'd be nice if it was a sticky too :(

Thanks for the reply. I am not so worried about the funds for the stabilizer as I am actually getting a car. I currently live in Bangkok, and will be moving to VA this December. I know the 3's are popular cars, and I will need one fast once I hit the ground. Hopefully, the new MS3 will deflect some of the demand from the regular-old-boring-run-of-the-mill-NA-3 I want.

I read your stage two write-up. Very nice. Regarding the TB coolant bypass, I am surprised, considering the apparent collective knowledge of this forum, someone has come up with a manually or thermostatically controlled actuator to bypass coolant from the TB during normal operation, and allow coolant (warmant?) to flow when conditions might cause TB freezing. Were I a whole lot smarter, I might just be able to come up with something.
 
excellent thanks for the ideas, this simple mod is a new one for us in Australia...some have done the whole voltage stabilizer but not TB grounding as a simple go between.
thanks

You AU owners are lucky you don't need the TB ground as you have cable-driven TBs. I think the TB ground is actually grounding the throttle position sensor, not the TB itself per se.

Since you have no need for the TB to be grounded, what are the typical ground points for you?
 
i know from looking at a mates engine bay the block and body are earthed and from memory he had one on the TB but i will get back to you with exact details.

these worth doing to an ms3?

1. Throttle Body Ground - IIRC MS3 has a different intake manifold (not made of plastic like on the normal mazda3) so you should be grounded through that)
2. Full Ground Kit - Voltage Stabilizer/Condenser Kit
- Your call on that one. For the most part I think they are just an item for show, a pathetic attempt at padding a mod list, etc.
3. Intake resonator removal - MS3 has a different intake (obviously) so it probably doesn't have a similar resonator in the intake.
4. Panel filter replacement - A nicer air filter than the usual paper stock filters is always nice.
5. Short shifter- If there's a short shifter out for the MS3, hells yeah. It's one of the first mods I did to my Protege5, and I gotta say it is one of my favorites. After a while you might forget your car has a short shifter, but drive a car that doesn't have one and WOW it's a shocking difference. Before I turboed my car, I drove a friend's stock Mazdaspeed Protege and the difference I noticed much more than the difference in speed (the MSP barely felt faster than my Protege5 with lots of NA mods) was how long the shifter throws were, and the Mazdaspeed Protege even comes with a factory short shifter (fairly pathetic IMO).

lol, funny-- considering I even have a dyno and some files proving it's better than the apexi and even the basic throttle body ground.

EVERYONE who has purchased one who has installed the BCC like it.

so...padding a mod list? ;)
 
does anyone know if adding the k&n give you better gas milage because there are a few threads that say it gives you more power but less gas milage
 
Just finished grounding my throttle as my first mod.
I used a nice 4 gauge wire and some hardcore copper connectors, not sure if it's a bit of overkill using such a thick wire... but hey it was cheap and if anything is worth doing. It's worth doing right!
Next step is the intake baffle... thanks for a nice post.
 
Mazda Design Challenge

Mazda kicked off a user-generated-contest with Facebook on 9/20. The contest focuses on design.

College grads describe a hypothetical 2018 Mazda concept car with words or sketches. The top 5 get to

develop their concepts with the Mazda design team, and the winners design will be unveiled live at

the 2007 LA International Auto Show.
