Lighten the stock fly wheel?
My buddys cusion works at a engine building shop so I can get my fly wheel lightend for cheap, he already had this done in his 400whp turbo 240SX..and liked the benifits from it.
How much can you take off a LS1 fly wheel? without causing much problems and still showing some gains
thank you

Probably nothing.
If you surface the flywheel, normally done during a clutch rebuild, you will lose only a couple ounces of weight(if not, less) and you will be increasing your chances of developing hot spots and wapring your flywheel.
When the flywheel warps, your clutch will probably start to chatter and it will only get worse from there.
You can buy lighter weight flywheels, but I would NOT lighten the stock piece.

Depends on how beefy the stock one is. I haven't seen what mine looks like or how much meat is on the backside, but you can usually turn down the backside quite a bit to drop weight. The guy I bought my old Nissan racecar from had the stock piece turned down on the back and dropped around 5 lbs. Of course, that's 5 lbs. less material there to absorb heat which means that heat will have to go somewhere, and that somewhere is mainly the clutch, but again, it depends on how beefy the stock unit is, how much you're taking off, what type of clutch you're running, etc. Hope this helps.
