Aluminum flywheel?

[Rich Z]

I can think of pros and cons for having a lighter flywheel, but what have other people experienced trying them out? Would it be a better match for a turbo powered car? Is there more clutch wear to worry about?

When the time comes for my motor swap, I want to get more of these ducks lined up in a row.....

Well it all depends on the type of driving you are doing,
an aluminum flywheel package will rev quicker and decel quicker which is what a road racer would want, a drag racer would want a steel flywheel for inertia which is suppose to keep the rpms from falling as quick as the lighter flywheel and better for launching the car.
In my opinion with your car I would do a duel disc setup I know your car will rarely see the strip and supposedly the drivability is as good as the single disc setup without the clutch chatter of the stage 3 and bigger single disk clutch.

But what about the flywheel in just regular driving on the street? And what effect does this have on the turbos spooling up? Does a heavier flywheel give more load for the turbos to work off of, or does a lighter flywheel allow the engine to spin up faster delivering more air more quickly to them to spool them up faster?
