I am looking for a aluminum flywheel for my SE any one know which years are interchangeable if any? Thanks

 

As long as you have the correct rear counter-weight, you can go with either 225 mm (the orig size) or 215mm (thats if you don mind switching to a smaller clutch assembly).

 

Yeap its 225mm but you will need the automatic counter weight from a '74-78 Mazda Rx-4. Since there was not a automatic tranmission GSL-SE.

I can look up the part number if you need it, Mazdatrix still sales the counter weight.

225mm flywheel was used on '83 and later 12a and 13b engines (non turbo).

are you sure you want to go with the alloy wheel, and not the light steel wheel ?

 

Bring On Your 12a Thanks for the response if any one has one for sale I have cash

 

Mark - why not go with the 12lb Al flywheel in this instance?

I posted up here about 2-3 months ago basically asking the same question, since we have very few 'mountain' grades here in AZ desert, and the lightweight Al wheel will likely net me the most acceleration for the money and effort.

Just interested in people's perspectives on lightweight Al vs. Steel. TIA,

 

i read somewhere, mazdatrix, or rx7.com,,,, i forget. talking about flywheels alloy vs steel. the alloy's are what ultra high rpm racing type engines that get torn down between events would use,,of coarse. the light steel is said to be a better setup for street, be it 12a's or 13b's.... long duck his 5th and 6th ports do not work the way thier designed. the low-end torque that you and i are used too
in the 13b re-egi, he turned them off..i would think the 13b re-egi in the -SE's
make the power they do because of the 5th and 6th ports , right and even though it's a rotory engine the 13b re-egi is not the real, or best choice for a ultra high rpm street machine. of coarse with a light alloy flywheel the engine WILL spin-up fast. but remember it's an 13b re-egi and it's limited by the injectors and MAS sensor and won't flow any more CFM's so light flywheel or not it's only going to perform to a certain point. now a 4 port cosmo 13b,,,fresh is a different story. as far as alloy vs steel, the steel doesn't wrap as often as the alloys. counter weights is not the issue. i wonder how a -SE (13B re-egi) with 5th and 6th ports intact with a alloy flywheel would act, as a noticable differance. what the trade-off would be.

 

SE's are crap,let's run em!

 

crap

 

All im lookin for is a little quicker off the line for auto X, I think the Fidizna one on Ebay will work. Mazda trix says all 225mm up to 93 so I think Im good thanks

 

Since you are aware of MazdaTrix, you should read about the advantage and disadvantages of a lighter flywheel.

I have found that the engine will rev faster from the line but you will be moving slower. I like a smaller wheel-tire combo for autoX for faster accelleration.
