I want to build a 6-port for power some day, but the secondary ports close too late with the sleeves out and flow too badly with the sleeves in. The 6-port is a lose-lose. You can get relatively good low end, but the high end is terrible, or you can get all high end and no low end at all. funny that this is exactly the issue that it was intended to fix...
I still wish you the best. What intake manifold and carb setup did you decide on?

Yes i have 6 port that im rebuilding just in the mean time while im waiting for my special project to become more feasible.
I think ive found a good way to solve the secondary port problem or at least make it not as bad. Well i guess it was pineapple's idea. They have inserts for the secondary sleeves that make the flow alot better. Im going to use them. Hopefully these inserts work as well as they say they do. They claim something like an 8hp gain from these alone on their website.
Ive also had my secondaries wired open since i bought the car. I had full exhaust (RB header,PS, and 2.5in pipe.) HKS intake. I was making really good, strong power at 3K rpms every time. never had an issue.
Right now im looking at getting a Weber side draft set up that Mazdatrix sells. I hope it all works out. Im gettin excited for it even though its just a temporary fix so i can drive my damn car haha. Thanks for the support DOHC.
