Anyone have any ideas on how large of throttle body I need for my Renesis?
I really don't even know where to start to try to figure it out? I have a
RX8 workshop manual, but I can't find anything in there that would help in
that area, mostly just deals with Mazda part numbers and troubleshooting.
Unfortunately Mazda left out the Aviation R&D section in my manual.

  Also, I am interested in (and mostly curious) how many guys are using
the Renesis, and at what point you are in your build. I have spoken to a
few guys that are going to use it, but have found few that have started on
the FWF with it. Tracy obviously excluded.   Ben Schneider
