I've done a few fully bridgeported 6 port engines. I also bridgeported my Rx8 renesis engine. It's my daily driver. I really like the bridgeported 6 port engines. They have some serious potential. many people just disregard them.

no dyno results. just a video of the 87 bridgeported rx7 vs a 91 turbo II in out local street drags. the bridgeported rx7 beat the modded turbo II. A friend of mine dynoed his 6 port bridgeport rx7. we are not happy with the results. We had some lost of power. best hp was. 180rwhp through the mufflers. he found some problems with the exhaust sytem in his car, soon he will dyno again.. I am lookin g for 230rwhp..

connect the dots. make the eyebrow larger. spend some time porting the back side of the opening of the port. (inside the runners) if you make the eyebrow larger, your going to need a differen t apex seal. I use atkins 2 piece 2mm apex seals with oem apex seal springs. works great. I could go on and on about how you could improve your ports. Are you bored? this could get long.. today is sunday. I guess we could write a little.. go ahead ask more specific questions..
