K so I have a fully built n/a b series and had a stock b16 trans on it. We'll I blew the trans up at the track ( I think the diff went). So now my question is do you think a b16 or gsr trans and then an mfactory lsd diff, or a stock OEM type r lsd would be a better route to go?

 

B16 trans, MFactory helical LSD, MFactory close gear set and/or final drive to match your setup and usage.
