boost

[oaklandopen]

This makes me wonder what all those 2010 mustang V8 owners are doing (besides kill themselves). Are they trying to throw money at their 4.6 or are they cutting their losses and getting rid of it for a 5.0? Poor guys

giving the variables and dumb luck 7-8psi is about all the oe internals will take, to truely build a sedan abel to take a respectable amount of boostl and when you properly do it will far exceed a stock speed in terms of whp, you need a serious grip of cash, say $10k, but put it in perspective, you buy the car for $18-22k depending on the package, ie base model or s-touring and add @ $10k = $28-32k total cost and you have a car that can lay the smack down on any stock evo or sti....stock ms3 is now a joke and not even worth the time in comparison....but the investment in time-work-research etc...far exceeds the $28-32k, basically boils down to the enduser really being into his car in the mechanical aspect....anything is possibel with enough cash and knowledge.....and a sucessful conversion project cannot be approached half ass manor and you need to know exactly what your doing beforehand.....not A good idea to go inot something like this green.

i dont like the hatch plus i think it would be pretty cool to have a boosted sedan

Don't listen to them, im boosting my sedan I will stomp the "real speed3's"

If you want to do it, I say go for it

 

[05Mazda3sp23]

or you can swap a MS3 motor and transmission into a sedan
and dont say it cant be done, because I have seen it done, in person, and its AWESOME

i would like to do this.... cuz its best way to have boost sedan, than to keep putting money just to boost.. also in the n/a, i read somewhere that the oil channels are 1/2 the size of turbo engine and tranny dont last long on n/a with boost lol... so ya swap is best way to boost sedan, i think

 

[infamouszoltan]

i thought about doing this but after some looking carefully i found that regualr 3's boost better then the mazdaspeed 3's.... thats just what ive read

Not in the corners...
All Speed3s come with swaybars. The Sedans don't.
If you're comparing the stock Speed3 to a boosted Sedan with everything else stock, you'll get ***** on a track.

depending on the driver!

 

[superdoughboy4]

That's true too, but I'm saying it as if both drivers are of equal level.

 

[infamouszoltan]

then i would say yes probably the speed would the boosted sedan. the reason i say i can beat speed 3's because in my non boosed car i've beaten a mazdaspeed protege and 2 1.8T jetta's

 

[superdoughboy4]

The Speed3s are tuned at 280lb-ft torque.
Our dinky Mazda3s are tuned at ~140-150lb-ft torque.
You won't get a 130-140lb-ft torque increase in power with just a simple low-pressure turbo.

 

[infamouszoltan]

But turbo isn't all I'm doing, that is just what is happening at the moment I have plenty more coming and soon enough my little 3 will be eating s*** alive! Haha

 

[oaklandopen]

Well its a good thing you decided to pump out as much hp as you can from a 2 liter mazda3 sedan instead of getting that bad '05 zo6. Although I'm sure when you are done with your mazda you'll be stomping vettes left and right

$ well spent!

Thats lots of cash to stick into a car tho

I'm not going to argue because yes you can swap a disi mzr into a sedan....but seriously not to sound like a broken record you would basically need almost a complete MS3 donor car, you would be running the ms3 ecm, ecm wire harness, engine, exhaust, fuel lines, transmission, slip shaft and cv's, shifter assembly, slave cylinder and cables..this would bring you to ground zero-the output of a stock MS3 about 210-220whp....the 260 the factory claims is at the crank not the wheels..and you would still be stuck dealing with the anemic borgwarner oe tc that falls flat on it's face at mid high end well before getting to the red line, it does have a little head room using a boost controller to manipulate the waste gate but not much, now add additional engine management, a fmic that doesn't heat soak like the oe tmic, a larger flow tc, etc.....can be done but why when you can easily accomplish the same and more with a built regular mzr.

I approached my build from the aspect of looking at what the MS3 package had that made it truely a good performance package.....the transmission stood out foremost to me, you would have to spend upward of 5k to build the 5spd to make it equal to the ms3 6spd...trust me I priced the parts and labor to build a 5spd that would be able to hold 300 plus whp without imploding and we are talking about straight cut gears and a qauife lsd....which would make it a track car only unless you consider yourself a saddist.

I'm not here saying I know everything there is about these cars but I do have a deccent amount of experience.

Performance wise think about the weight to power ratio, a 2005 Ford Mustang Cobra has a ratio of 12.5lbs to every 1hp, my car car has a ratio of 7.1lbs to every 1hp.

As I said before about the cash investment, think about it , how much does a evo or sti cost off the showroom floor? close to $40+k, how would you feel if you bought one of these 2 cars and you got your ass handed to you by a little mz3 that cost in total $10k less ? Look at what you would be getting for that investment (after you go through the set-up which I' am not going to lie can be a royal pia at times)

Umm btw my ouput on a Mustang Dyno is 368whp, on the engine dyno (crank) 435chp....um ms3 are like lol w/e...
Basic mods are a low end forged built mzr at 8:1cr, arp fasteners everywhere, gt2871r (26psi), ms3 6spd transmission, inline 255 walbro pump system, HKS full stand alone piggybacking the ecm on open loop aspect of fuel/timming, mechanical tb (to overide the oe speed limiter) about 5 months of buying, locating, sourcing, building and tunning....it is a daily driver with head room to hit 600chp with moderate additonal mod changes.

Umm odd my sedan came with sway bars lol, pretty much all cars have them.....a better arguement would of been "a sedan's 5spd transmission using an open diffrential will not out corner a ms3 which has a limited slip diffrential"

explaination: an open diffrential sends all availible power to the tire which has the least ammount of traction, which while cornering would be the inside tire because of weight transfer, inturn this causes excessive understeer, and a limited slip diffrential sends an equal amount to both the inside and outside tire -equal power distribution is always more better.
