Check out the porting pics on Vosko's web site. Vosko.net/photos. I believe these ports are from Ito. If what he say's is true, his 6 port is making as much a my 4 port BP. Just something to thnk about.

 

SPZ510 - I had a wander through Vosko's pic collection but couldn't find a bridged 6 port. I found a 6port that had more metal removed than what I knew was there to start with.... and a 4port bp with one of the thinnest bridges I've seen.... but no 6port bridge. Got a link?

I'm not driving the 6port 13b in my recently acquired early 1st gen (almost called it and s1... darn us aussies) as it needs a few little things before I can road register it. But I did drive my 13b bp FA3TS today.... nothing like a car that will turn on a dime and pull hard (until the street exhaust chokes it ) I will be real interested in some back to back comparo's. Hopefully the engine in the rx7 will last long enough for me to learn to drive it around corners before it needs a rebuild and goes to the porting man.

editted coz buzz can't spell
