Ideas on Upgrading the MS6 Power
 

The MS6 will come with about 287 hp, and 280lb's of torque at 4000 rpm. With the relatively small 2.3 liter 4 cyl engine, is this thing going to be pretty much maxed out when it leaves the show room, or will there be options for getting another 50-60 hp out of it?

I don't know much about how hard it is to get more power out of an already turbo'd engine.

humm... seems like u may be able to squeeze more juice outta it... but outta a 2.3... maybe just a little more... not much....

Should not be hard as turbo cars are so fun to mod. The main thing is always tuning which will get you a long way. Just don't go bumping boost and think everything is fine. The 2.3 has already showed that it can handle the MS6 power in NA (ready for turbo) form. I really like the 2.3.

Yea the thought did cross my mind, of getting the V6, and putting a Turbo in it. However I get the feeling that I would kind of be the only person on the planet trying this and not have much support from others.

And the MS6 is going to be AWD, and have a very stiff suspension/body.

I wonder how hard it would be to stiffen up a stock 6... Any thoughts on this alternative?

Aren't you putting the cart before the horse, Mr Postmodder??!!

Shouldn't we be having these discussions AFTER you've decided between the 8 or the 6....?

i am excited about the new ms6. i wonder if it will keep up with or even beat the STI and Evo. as far as upgrading an already turboed engine. simple. let it breathe. exhaust wise, the turbo itself provides enough back pressure so 3 or 4 inch pipes will allow all that extra air to get out of the way. its hard really to say what to do to a car we have yet to see let alone find its weaknesses. either way i think this car should be taken seriously or there will be a lot of kill marks on its doors.

i wounder if the MS6 will stack up against the STi... maybe the STi will be better...

I think the STi and Evo will be better performance cars overall whereas the MS6 will be more competition to the Volvos, R32 (now out of prodution), and Legacy.

You do realize that getting 500hp out of an Evo 2l engine is very easy and there are plenty of 2L 4 cylinder engines making well over that if modded properly. It's going to mainly come down to how well the aftermarket supports the car. The 2L in my WRX is will be making over 400hp when I'm done with it should I not decide to get an Evo or an STi. That is without N2O.

With 0-100KM/H times of 6.6 seconds how can you even think the Mazdaspeed 6 will be close to an STi? Thats about as fast acceleration as an RX-8.

The new 2.3L is a totally different engine, it is direct injection, which we will have to wait and see what kind of effect this has an aftermarket performance. Yes you will most likely be able to squeeze a lot more power out of the engine, but only time will tell as a lot of factors affect how much power you will be able to get out of the car especially with the stock turbo.

I think the 0-100km I mean the 0-62mph are kinda conservative. As all other times Mazda has released for this vehicle. I could be wrong but I would like to see other independent tests.

the car isn't even that close to being released here and people talking bout making more power? 280 not enough? The thing is I doubt many people will buy the car and "mod" it---it is modded. Only a fool or a ricer would want to void the warranty for a few hp on top of a already powerful 274ish.

if you want to talk about modding a Mazda6 or a MS6 then you should head on over to www.mazda6tech.com . they are the forum in the know.

Some of us do not consider 280HP very much. I had over 350whp in my last RX-7 and over 320whp in one of my current cars and they both feel slow. Both are cars that weigh quite a bit less than the Mazdaspeed 6 will.

How to increase the Mazdaspeed 6 HP? 3" straight through exhaust with a turbo muffler, 3" intake pipe, front mount intercooler with 2 1/2 intake pipes, reflash or replace the ECU. There ya go just added a bunch of HP.

...just because it's factory-boosted doesn't mean it'll be easy to make faster. Think MSProtege - few ppl I know make more than about 230whp without being scared. :)

:D

Yeah, lets hope Mazda doesn't make the same mistakes with the MS6 that they did with the MSP. Unfortunately it's kind of looking like it may be the case with the direct injection, the tuner market won't be strong to begin with and the little support it does get may be turned off by the direct injection.

Best way to make the MS6 faster would be dropping a few hundred lbs off the car. 3600 lbs is a giant land yaht of a car. Its heavier then every single car in its class, except the G35x Sedan. Even the new GT mustang is lighter.

Standard 6i MTX is just a scant over 3000, around 3045 lbs.

The other big thing with the MS6 is its tiny tiny tires. First off its got bling bling wheels on it, with 215/45/18 rubber...pathetic for such a heavy car...that thing should be sitting on 235's or 245's, which it can't cause of the 7 inch wide rim...so first mod would probably be dropping to 17x8's and rolling the rear fenders, then trying to see if you could fit some 245/40/17's on the beast.

I wouldn't bet on too much power mods for the ms6 for quite some time...at least a year. Of course you'll get the easy ones, like downpipes, catbacks, intakes...but most of the ecu related adjustments will be awhile off. Then there's the thought of how much the engine can handle. The 6i 2.3 I4 L3 engine has a stroke of 94mm and a bore of 87.5mm...so the rods will be a limiting factor as to maximum power levels. Supposedly they are beefed up in the MPS 6, but how much only time will tell.

The standard 6i MTX doesn't get boosted very high before the transmission starts snapping (3rd gear goes first), as seen the scca world challenge, and in the 6i and 3s owners forums...so at least in those cars its the transmission holding the engine back, not vice versa. Of course the MPS has a untested tranny, so only time will tell on that.

I'd say as long as the rods, and that watercooled transfer case hold up, the car will do fine with power mods. Maybe then it'll be able to compete with the car's weighing almost 300 lbs less then it does (with more power). Right now, given the weight and relative power ratio, its best compared directly to a Volvo S60R/V70R, which weighs about 120 lbs more, and has another 30 hp. Those car's run a low 14 second quarter mile. But then of course, their underrated, (only 11% drivetrain loss to bhp, and the wheel ft/lbs is over 300+ (rated 295)) so I'd say mid-low 14's would be a safe bet for the MPS 6, about the same speed as the modded 6s MTX's.

hey crossbow- have you checked out www.mazda6tech.com? ;) that seems to be a pretty good site for info on the mazda6. you should check it out :)

It should be, its my site :). (Along with Stretch and G-cubed). I still love the rx8 though...keep waiting for mazdaspeed 8 tidbits...or rx7 ones :).

Btw for continued discussion, here's the MPS spec sheet from late november 04.

Please Right Click and Save As. Yes this text...Right click and save as. You can do it! I have faith in you!

Maybe if you add Nitrous or bigger turbo, but beside that, probably not much. Unless you have deep pockets, you could change out the entire exhaust system, go CATless, port and polish, you could probably squeeze another 50-80HP.

Nice site.

Why thank you kind sir! I hope you have a tributeless day!

Man I'm soo Confused.

I want an Rx8, with a MS6 engine.

Good thing I have 6 months to decide, maybe one of our FI friends will find a solution to my problems.

Well, it's already known that the internals for the MSP are untouched. Most raise boost and don't care about the ECU. In this case the internals had to be touched for this engine. Cosworth got the same power out of this engine NA while making it turbo ready. Im sure it can handle more...with the right ECU.

Ya but unfortuantly you won't be able to put your track tires in the trunk...because you can't put down the rear seats in the MPS 6. Sigh. (Used as bracing)
