Scoot's 6-port turbo????

I understand that Scoot used a 6-port 13b to make 515ps. Isn't this better than the 4-port 13b? More port volume = more HP? Why wouldn't I wan to use a 6-port engine for a turbo application, ie what are the drawbacks?

Is this something new I haven't heard about, or is this just confused with the secondary PP engine? They used a normal 4-port turbo engine and modified it to have secondary peripheral ports in addition to the four side ports... total of 6 ports.

Considering the 6PI 13B hasn't been sold in Japan since, I dunno, '84-86 or so? I don't see why they'd bother with one...

That special manifold and port job is more often called a combo-port or a mystery-port.
