i was reading some engine building information from an awesome first gen. performance website from japan. the website is www.22cworks.com. The basic idea of the way they port engines just makes so much more sense to me than a bridge port. it's a combination extend port/peri port, or small street port/peri. Because the placement of the peripheral port and use of the stock side ports, the driveability is significantly higher than a car of similar peak hp. i just thought i'd spit this out there and see what other thoughts were on it. personally, i'd love to try to build an engine like this one day. i would recommend anyone check out the site who's into rotary performance. just use one of those website translators.

 

sounds like a semi-peripheral.
