Well I finally replaced my clutch(with a Exedy OEM) with the help of 2 friends and while I was in there I went ahead and put in a lightened flywheel(10lb) from www.Sohfast.com. Its a factory flywheel that has been lightened, balanced, and resurfaced. It cost $140 plus a $60 refundable core charge. When the flywheel came in the mail the first thing I noticed is that it felt kinda heavy, so I weighed it, and it did weigh 10lbs.

The clutch job and flywheel install went rather smooth( I was ready for the worst) and took approx. 7-8hrs, it was a big help having 2 friends that had already done this. So with the help of a helms manual we tackled the job with almost no problems(THANK GOD!).

At about 8pm my time I started the engine and everything sounded fine(WHEW!), I revved the engine, still nothing weird except the engine revs faster, nothing crazy like Gran Turismo or anything but a definite difference. Then I put it in gear and there was a weird noise, I was like oh god whats wrong! But it was nothing to worry about just the new clutch breaking in, after a couple of times engaging the clutch the noise quickly went away.

So I take it around the block for a slow test drive and everything is fine, so off to my home I go.

My experience so far is this: the engine revs quicker(not crazy fast), the car accelerates faster (again nothing insane but a noticeable difference), I still gotta break in the clutch so I couldn't drive it too hard. The revs DO NOT drop that much faster, a little but again nothing absurd. Also the car doesn't seem to slow as much when its in gear and I let off the gas when compared to the stock flywheel.
These are my experiences with only 20mins of driving.
I'll write more when I get more driving time tomorrow.

Overall this is a very good mod for someone who wants better acceleration(who doesn't?), but replace the clutch at the same time and kill 2 birds with one stone.

By the way the stock flywheel weighs 18lbs, on my car at least.

Thanks for the good info. I considered getting a flywheel there when I did my clutch, but I decided not to go with one that was shaved from stock.

I was thinking of going with an aftermarket one but I didnt want to spend too much $ on this engine.
I really dont think that it'll really matter unless your making quite a bit of HP, which i dont plan on doing with my D16. I also asked them if it'll hold with a 50HP shot of nitrous and they seem confident that everything will be ok. But if you got the dough, more power to ya.

My Dad told me he had an aluminum flywheel on his Vette and he put on something around it called a shatter guard cause the flywheel is so light if it brakes you're screwed. I wanna put an aluminum flywheel on when I replace my clutch which I hope should be very soon

GJ Az... Good info to know.... Will do, but umm, have an automatic right now. When i do my engine swap i was planning on putting in a heavier clutch and maybe doing the fly wheel. I'll be doing the auto-manual swap at tthe same time too. Gonna have a shop do it though, that way if anything is frucked up i can blame them.

What he's saying though is not a bad thing. I don't remember the limit, but to race on drag strips you have to have one. NHRA rules.
