Would you mind elaborating on the ''threading of a fitting'' thing about the acv? If this is something that alows me to get the function of the acv without having to actually install the part then i would love to know.

 

the hole that goes to port air is round, so you can put a fitting in it. it does need a check valve to keep exhaust gasses out of the air pump when its off, but that isn't too bad. the FD has one, as well as the Rx8.

or even better you can use the FD check valve, and add a fitting to the block off plate, or gut an ACV....

 

Rotary Performance is has created a kit for the FD that requires 0 modification, and can produce 400+ wheel HP with all emissions intact. I just installed my kit and produced 411.5 at the wheels. Text me for pics and info. 254-290-6223

 

Sorry if im making this difficult but youre saying put a fitting in the hole on the inside of the lim where the acv normally goes? If so, other than tapping the block off plate what other way would there be to install the fitting and block the other two holes under it? Weld them shut?

 

its simple, see the round hole where the ACV sits? it goes to that rectangular hole under the intake ports, which goes through the center iron and then to the rotor housings for port air.

its round, you could thread something in there, or add a fitting to the block off plate or whatever.
