flywheel options..
 

Im gonna be building a turbo 12a.. now i know i need a T2 fly etc etc.. is there any flywheel option that does not require the auto rear counterweight? Just looking at all teh options right now.

Years ago, Mazda sold a lightweight flywheel that did not use the auto counterweight. Good luck finding one, though. Most were made for the 215mm clutch, which isn't enough for a boosted application. I have seen one of these. It wieghed in at 12lbs, less than the aluminum T2 flywheel and counterweight that replaced it......
What you should be considering, is whether to use a light steel, or aluminum. The light steel is heavier than aluminum, but much lighter than stock.
Also, what trans are you going to use? That makes a difference on the flywheel. For a NA trans, you need to stick with a NA flywheel. To use a T2 trans, you'll need a flywheel designed for the T2. Regardless of which trans and flywheel material you choose, the counterweight will need to match the engine.
You cannot use a stock T2 flywheel on a 12A, unless you have the entire rotating assembly balanced.

Yeah i plan on using a T2 trans.. everything is going to be balanced anyways i was just wondering if a flywheel was made that didnt require me gettting an auto counterweight for use with a T2 fly....

Short answer, no.
Just get the auto counterweight that matches your rotating assembly, and a flywheel for a T2, and you should be good to go. Having the assembly balanced is the best way to insure it runs as smoothly as possible, vibration-wise.
