Yeah, pretty much. It's like my definition of half-assing. I would equate it to slapping on a GT35 and leaving the stock exhaust.

Basically altering the port timing and velocity as much as a BP does requires a completely different intake manifold. It also requires much more fiddling with the fuel and ignition curves which you can't do. The potential in the port is there, but not really at a useable RPM without kinda sorta balancing the assembly to see the higher rev's, and at the higher rev's the stock mani can't keep up. How many superjillion yen did Mazda spend designing and tuning the stock intake to work with the stock ports? Ever hear of reversion? Do you think the mani is still doing it's job properly with such radically altered port timing?
