20b tb on my 13b-re
20b tb on my 13b-re
I picked up a 20b tb and was going to try it on my 13b-re.WIll I gain much ?I looked them over and the 20b is visually bigger inside .has anyone got this done ?
slightly bigger than the FD one IIRC.
I also have a nissan 90mm I was going to put on but need time to machine a few things .figured I would try the 20b tb for now .think I need to retune with this since it has more flow?
