using a light weight flywheel will increase your turbo lag a very slight amount. a heavier flywheel puts more load on an engine, causing it create more exhaust which spools the turbo up faster. of course the extra revvability of the engine will overcome most of that extra lag and get you up to spool a bit quicker, so like I said, it'll be a VERY slighty difference. personally I'd go for the light flywheel because the it'll actually relieve some of the stress on the engine, increasing its longevity.
