just got in my b18 GSR for my del sol and i'll be dropping it in once i get my shift linkage in, radiator hoses and drop in my lightweight flywheel. i'm looking at 2 different ones. the fidanza is 8.92lbs and i can get it for about 195. the ACT streetlite is 7lbs and will cost about 255. is 1.92lbs worth the extra 50 bucks? i'm building it for all motor purposes so i need every bit of help i can get.

 

Do you have an extra 50$? I'd get the fidanza. And I'd look on ebay :

i would just go ahead and spend the extra $50..

 

Id say 1.92 lbs is about equal to an extra 1-2whp up to you. I got my 7.5lb fidanza flywheel for $150 shipped from a special on honda-tech.
