I only want to port the exhaust not the intake just to let the exhaust get out faster, is this not worth doing? bhr e mailed me back they are not doin builds at this time. oh well ill keep looking. now I believe that these motors are very hard to build the first time I went on prodemand it has all the specs you need. I have built a good number of motors before. I'm torn, I know I have the skills just not the experience and as you all pointed out these motors are very finicky I just want to dive in. its hard to have patience.

If the message isn't clear enough, no, Bridgeporting is useless. The rotaryengine.com(RX7Specialities) you looked at have a porting service, but it's not Bridgeporting(which they actually don't do on the Renesis because even they know it's a waste of time and money). The shipping will probably be expensive, though.

General problem is simply that you can't open up the exhaust port much without hacking into the water jacket. Once you do, the whole side plate is useless.
