whats inside the ms3 motor??

[nig3]

New owner here(spin) uuuhhh so this 2.3 turbo motor...... whats the scooop on the inside components?? does it have vvt, oil squirters, any forged parts, how well does it respond to mods? whats the most whp you have seen on modified ones? are they able to take abuse/do they last?
all i know is that it makes great power from the factory and is a high compresion turbo motor with direct injection and runs a million psi of fuel pressure. please teach me, thanks!!!

No one knows how long they will last as that car has been out almost a year.

Here's the sure fire link to all you would ever want to know.

Well first you should search the forums...there's a lot of info on that very topic.

VVT? No if you're looking for that snag up a honda or mitsu.

The engine does have forged parts. I believe the rods and maybe the crank, but not the pistons.

Oil squirters? No I don't think so...although there is supposedly some sort of system that helps to cool off the turbo after we turn the car off.

I have a CAI on my MS3 and the car responded very well to it and some people claim up to an increase of 20hp with just that single mod...i don't think it's quite that much, but the CAI sounds incredible though and is worth the $$. CBE will give you a little extra hp too, but is probably not as good of a mod as the CAI. A few companies make upgraded TMIC, but I don't see the point unless you're going bigger turbo, although the TMIC install is supposedly and easy one and not very time consuming one. Other then that I would just keep searching.

The only other mod I want is a short throw shifter...i miss the msp nub shifter

good luck

just curiouos why you would say somthing like that? vvt would work wonders for a boosted motoer and most new motors have that feature. its not a honda or mitsu thing unless you meant to say vtec.

False...the MZR does have variable valve timing. Pretty much every good engine these days does, and our turbo version of the MZR is one of Ward's 10 best engines.

Here is some info on the base non-turbo MZR 2.3:

You can also go here and click on the "Engine & Mechanical" tab to see VVT listed in the spec for our turbocharged MZR engine:

Wrong !!!! , what r u guys talking about, this engine do got vtak on it. i hear it all the time on high rpm, thats when my vtak kicks in, s***, this is the best vtak engine eva made.










lol jk, just admiring the good ol days with the vtak

I think it might have pistons. Not sure though. Cylinders. Definately cylinders.

your an idiot. all mazdas are rotary.

On another forum I belong to (non-vehicle specific), and this is an exact quote from another member.

I was pulling out of school the other day, and another student has a Mazda. It has a V6 badge on the back. I thought all Mazdas were rotary powered. Is he just a huge ricer?

True story. Le sigh.

 

[Haltech]

With a conservative tune, this motor should easily hold 450hp to the wheels.

 

[Captain KRM P5]

there are oil squirters in this engine.

the rods are cast, the pistons are cast, the crankshaft is forged. same as every piston mazda engine before it, sorry guys. see the attached pictures below. if people want pictures of the pistons as well i have those.

left - factory cast iron mazdaspeed DISI rod
middle - eagle forged rod for 2.3
right - factory cast iron mazda protege rod bent

 

[tru-boost]

i'll be damned.... yep those are cast !!

This will tell you everything about the flippin' 2.3 disi turbo engine...
http://media.ford.com/mazda/article_display.cfm?article_id=24323

Creating the DISI Turbo engine involved more than just changing the injection system and adding a turbocharger, though. The form and materials used for the major components are optimized to bear the added load and heat of the increased output. The aluminum cylinder block and cylinder head are made using a new implementation of the Mazda Advanced Precision Casting process, which increases their strength. In addition, cross drilling between the cylinder liners and between the valve bridges in the head improves coolant flow and heat resistance. The crankshaft and connecting rods are made of forged steel, wrist pins are a new full-floating design, connecting rods have an optimized shape and larger journal size, and pistons are designed for maximum stiffness and durability.

the rods are not forged steel, i am sorry. the article is incorrect. we have disassembled three of these engines. all of them have had cast rods, with casting marks in them. they are definetely an iron rod as well. the bore for the crankshaft and wrist pin are machined, but the rods are cast. forged rods are made through a pressurization process that does leave the type of surface shape or texture that a cast rod does.

I love how even the old N/A KL V6 in my '93 626 had a forged crank. What I'd like to know is why mazda chokes off the boost/throttle plate at high rpm? Can the turbo not flow efficiently above 5500rpm? Are they just tuning extra-paranoid to avoid another warranty fiasco (like the FD RX7)? I love the torque, I just wish the engine wouldn't fall on it's face so early. That would make running through the gears a bit more enjoyable.

they'll never say that publically, but i'd say that has alot to do with it. why do you think we've never seen a 'mazdaspeed rx-8' ?

article is correct, they are forged. Not all forged rods look like what you show in your post, common misconception. Forged rods can look like cast rods as well, that doesn't automatically make them cast...

The article is most definitely correct...its from Mazda's corporate website. I think they know better than anyone exactly how their engine is manufactured. Plus the engine is a four popper making 280 ft lbs of torque! If you want a four cylinder to have any sort of long term life expectancy with that kind of power you need to make one hell of a strong engine which is why mazda's 2.3 disi mzr and even the new caliber srt-4 have forged parts that make up the engine.

And I've found no proof of VVT in the 2.3 disi mzr..our engine's power band drops off significantly at around 5500 rpms...if anyone can show me any proof of VVT in our cars please let me know as my ms3 certainly didn't come equipped with it. The same thing goes for oil squirters...no where have i read that our engines have this and maybe i'm wrong but i'd compare that to a dry sump oil system that are on many high performance autos like the new vettes...maybe i'm wrong though since 'oil squirters are on the new srt-4...

hahaha, yeah you forgot to mention, valves, rods and don't forget the crank!!

ugh again, VVT doesn't necessarily mean high rpm power. Its not like Honda's VTEC, its variable valve timing and yes your MS3 does have it.
