After i installed the NST ud pulley set including alt and pump 9mths ago i loved my xb more but lately I've been searching for a lightweight flywheel for a long time now and haven't found any solid info. all i've found is for the tc from either fidanza or clutchmaster. since both xb and tc share many same engine parts i wonder if the tc flywheel would work with the xb. have anyone tried replacing or upgrading their flywheel? thanx for any info
