I have one on my RE, it is slightly bigger, but not by much. It's also
slightly bigger than the FD one IIRC.

I am running a FD TB on my 20B. I have heard the FD TB is better..

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?
