MS6 Turbo in a 3?

[RHAGEL]

The MS6 has direct injection so the whole intake system is different. As said before, by the time you bought all the parts from Mazda, a new ECU (and custom programmed it) a new clutch, and got it all installed, you are looking at quite a bit of money. Probably twice the cost of the hiboost kit.

 

[RHAGEL]

the reason that they put the 2.3L in the MS6 is because they wanted to keep the handling of the smaller engine. the V6 is to heavy and bulky for cornering and handling. so they decided to keep the lighter engine in it and turbo it so i can still have amazing handling.

This may have been part of the reason but it is mostly due to the fact that an inline 4 cylinder is much more resposive to a turbo than a V style engine. Not to mention it is cheaper to manufacture.

yeah the mazdaspeed 6 has a turbocharged 2.3L 4cyl I thought it was odd myself that they chose the 4cyl over the v6 but I'm sure they are smarter than I am

Have you ever seen the engine bay of a Mazda 6s? There ain't much room in there for a turbo

not one turbo two turbos... isn't that why the V set up is so sweet? you can turbo both sides of the engine... that way you have smaller turbos and can fit them in smaller areas... i am just dreamin here but it would be interesting...

I believe a bi-turbo set-up is used to reduce turbo lag. One turbo is set at a lower pressure so it will spool faster and create more power on the low end. The second turbo is used at a higher pressure to increase power on the top end. You don't have to indepenently compress the air for each cylinder bank because they use the same intake manifold. I think it is also harder to turbo a V style engine because of the amount of power working against the crankshaft. You figure the back and forth movement is hard on an engine, especially when boost kicks in. An inline engine is smoother and more linear because all the movement is struictly up and down, not at 30-45 degree angles from each other. For Mercedes, Bently, etc. to add twin turbos to a V-12 takes a lot of presision and balancing to get the engine to run efficiently. Whats crazy is the new Bugatti with a quad turbo W-16 and 1001hp.

Anyone feel free to jump in if I am giving inaccurate info.

OEM turbo's are usually safer,only because they are always low boost.

aftermarket turbo's are a lot more thought out(if you buy quality)

MS6 turbo is supposed to push up to 15 PSI stock (Mazda's info on the site).

Sounds right. The MS6 was originally supposed to be a bi-turbo engine, but that idea got squashed pretty quickly by some bean-counter.

That's one way to set it up (small turbo for minimal lag, then the larger turbo takes over at high RPMs for lots of peak power)....but many twin turbo cars have two of the same turbos. Works great for 'V' or boxer engines.

Turbo's are so much better designed today that a single turbo that is capable of supplying enough cfm for over 500 whp in a 2.0 liter 4 cylinder engine with virtually no lag with the aid of proper electronics. So that being said it has nothing to do with outright power but rather a package that is affordable to a broad base market also considering operational cost to the consumer including insurance and maintenance. I think Mazda made a good choice in going with this package. It gives some that would buy a Audi, Jaguar etc. a cost effective alternative.

Ok, enough with the blah, blah, blah...... after market turbo kit for the 3 such as Highboost is the most cost effective choice at the moment apart from going custom. We have a kit for the MZ3 coming out in the near future so that would also be an option. So far we have made VERY, VERY GOOD numbers and reliability is also inline.

Who's we?...if thier is another kit coming some details would be cool

i was going to ask the same question but it didnt make sense to me.
it will be cool to have a 3rd option.

The 2.3L just seems to be a glutton for boost doesn't it?

 

[doogie]

Yes, could say that..compression and head design and also a solid botton end make for a great candidate..(yippy)

did you guys see the new dynos from HiBoost?

all we need is someone to wrap their ms6 around a poll... so someone can buy the tranny and engine and get to swapping...

Although, that would provide ample opportunity for this engine swap, I hope not to be the donor. Driving home last night I thought it might be possible (-15 degrees Celcius, black ice ALL over the place, 8 accidents in a 5 km stretch), but I managed to make it home in one piece. Sorry guys...LOL...I thwarted your plan this time.
