Lightweight Flywheel and Turbo?

Lightweight Flywheel and Turbo?
I'm getting a little rusty on my automotive theory, mostly about if having a Lighter Flywheel is good or bad or ugly on a car that utilizes a turbo.
I would imagine that it would help the response of the engine while off of boost and really not have any downsides while on boost...but what do I know
I've got a 10lb flywheel (1.8L) sitting on my desk and have intentions to install a begi kit at some point this Spring. I was also going to have the flywheel and new clutch installed prior, but don't want to make a mistake.
Any advice?

You'll have no real problems with the flywheel. I find on my car it can take a second or two for idle to stabalize. Mine is a SPEC 8ish lb aluminum unit. If I had to do it again I would have stuck with a stock flywheel, any gain from the flywheel is overshadowed by the turbo.
I'd sell the flywheel to fund the turbo install.

I have a lightweight flywheel on my 240Z, and it's tricky - car tends to bog when the clutch is engaged. Of course, that's with a beefy cam and no low end torque.
So, I guess maybe this has nothing to do with your thread. Oh well.
I wouldn't bother with a lightweight flywheel again, on anything. Throttle response is nice, but that's about it.

I hear a light weight flywheels biggest downside is in traffic as the engine no longer is able to pull the car along at idle.
I was considering a light weight flywheel too but living in NY I sometimes get caught in traffic. its nice to just put the car in second and have the engine idle pull the car along at 5 miles an hour. I imagine it would be a problem with a lighter flywheel.
Besides the throttle response on the miata is pretty quick as it is, i cant imagine what it would be like if it was faster.

Due to the reduction of weight. The flywheel can not really give the same momentum as a heavier (oem) flywheel. This is what people have a problem with.
The lighter the flywheel the more you will lower your moment of inertia. That equals a faster up rev and down rev. Thats a good thing to me.

It isn't going to help spool directly. It'll help the engine reach higher RPM faster (in theory), so it'll aid the turbo getting up to speed quicker. It isn't the same thing. Not like the flywheel makes the turbo spool 500rpm faster, it might make the engine get up to 4000rpm faster. It's like saying light weight wheels help the turbo spool faster.
My opinion is that it's placebo. Any percieved difference with the flywheel will be lost in the gains from the turbo. It'll be like tears in the rain (sounds cooler when Rutger Hauer says it).
