I'm saying that the stock intake will make the best power on a stock engine, because it was designed around the torque characteristics of the motor, something you can't do without a lot of understanding and experience, and money.
CAI is Cold Air Intake. It sounds pretty, but probably reduces your torque output down low, because it will be less efficient than stock down low. if you're lucky it might add some HP higher up.
your ignition upgrades won't make you any more power. I wouldn't mess with your fuel pressure regulator unless you had a wideband O2 to see what it was actually doing to your AFR. More than likely you'd just confuse the hell out of the stock computer.
I'd leave your clutch. Clutches only really need replaced when they wear out or slip under the power.
Exhaust, on the B6, I probably wouldn't go bigger than 2". The effect of the exhaust is using the vacuum behind exhaust pulses to draw out the following exhaust charge. This effect is primarily tuned in through the primary runner lengths, and the secondary lengths if you have a 4-2-1 header. This will cause a bump in power at a certain RPM range (and removing that bump from the stock header point). Additionally, the entire resistance of the system (sometimes called back-pressure, more accurately called head-loss) can change the point where the pulses draw most from the following pulse. Making your exhaust too large moves this point out of your use-able RPM range. Making exhaust too small can put it very low.
In order to TUNE anything, you need to rip out the stock computer and replace it entirely, with something like MegaSquirt or an AEM unit. Then you need to read lots and lots about engine tuning, unless you have a lot of money.
Some success can be had with a piggy back unit, which is a little box that can change a few things, but the versatility is way less.
I think you just need to start reading. read lots, and then some more.
These ebay chips, and the fuel orientation magnet are all total bulls--- marketed towards people who don't have a hot clue about how engines work. read more, and you'll get a better grasp on what making more power requires.
as for the intake i dont have the stock box anymore so i guess im SOL on that one ill just change the head it might be too old and dusty im thinking put a k&n air cyclone head on there. so theres nothing i can do to the intake to tweak it to take in more air?
fuel pressure regulator. ill change that maybe if i can find a performance one. theres this corner peice thats right before the fuel rail. my friends got the same car as me they changed that part and they said it gave better performance i forgot the name of the part ill talk to them later about it.
whats a wideband 02? and im not looking to sauder anything really just a few things i can throw on there to make it a little better. can i put some kind of performance distributor? i saw msd got a wire set with a cap and rotor and they DID have some kind of distributor.
so i can just use any 2 in pipe right? but i need a certain header, and cat, and resonator and muffler right? so if its just two inch pipe thats cool but what would you recommend for the headers and such? i do need to change the exhaust.
and i see about the tuning. well i think id just rather aim for a piggy back unit what do you think is good?
tuning will take too much time i dont want to rip out the computer if i dont have to....
BUT if i had to to put just one chip could you point out to me what kind of box. or is it just a performance box or is it specified for the mx3
i still need to do the brake lines and stuff but i want to get info from people first before i start doing things and wasting money. if anything i got a guy that could most likely help me with all that im learning everything from him. as for tuning stuff i think he knows but we never do that at the shop so if he knows i never been able to see him in action. maybe one day but he DID tune out these peoples cars in cali so they could race and he got money when they win the race and stuff.
any suggestions on what i should doto the car OTHER then a motorswap? if i could the only thing i would put is BTP GTR but thats imposable to find so i gave up. maybe ill put a turbo on this a long time later but for now just want to do a few things. i got some HID off ebay 8000k hopefully theyll be nice i only paid 35 bucks for it
hopefully tomorrow ill be doing that gear box fluid flush and that damn o ring and get my inspection to pass. i hate gear oil it smells so raunchy i hate it as much as working on the gas line. i bet ill hate working on the brake lines too. smh and mostly the antifreeze problem is almost gone but its leaving my fuel inject all screwy idk ill see in a week or two. and i got a flat tonight drove it all around then when i goto park it then thats it i fill it with air and see its the sidewall is cracked the tire is old. so back to the junkyard tomorrow. going to wait put the swaybars and get all new tires and an alignment
