Howdy! While I don't own an rx8 I have a 280z who's motor needs too much work for what it's worth to me so I have been thinking about swapping something else in. The option that seems the most tempting right now is a 6 port 13b Rew out of an rx8 which can be had with ecu and wiring for around 1.8k with a 6 speed manual on ebay. I have always liked rotaries and think it would make a great car as the 280z is super light and that engine will make it even lighter. Anyway i know some ecus freak out if they are not connected up to the correct gauge cluster with out reprogramming. I have been trying to find more information about swapping the 6 port 13b Rew into things but i haven't had really any luck finding information so I am here to try to get educated on the motor so I can figure out this swap. Also if anyone around Indy would be down to have me as a passenger that would be awesome. You can talk numbers all day but what really matters is how the engine feels and makes power.
