Can you tell me what the extra fitting is for?

Trying to figure out what this fitting is for and if I need to have it hooked up. |

Still working on cleaning up the engine bay, trying to figure out how to route my IC piping and what size piping to use. Shooting for 10 psi with an MSD boost box, cartech FMU, 305cc injectors, 190 HP pump and RX7 afm. |
Explain to me, please, why your BOV is the only thing going to the turbo intake.

Infinite boost:rofl:

As for the original question, yes, you need to run a vacuum line to the BOV. It's designed to open when the throttle closes, and it does that by sensing vacuum in the intake manifold. For intercooler routing, my advice is to do it the way FM does. Clock the compressor to point down, run the outlet pipe out into the wheel well and past the radiator. https://www.miataturbo.net/attachmen...ine=1323627187 --Ian |

Looks to me like there's a T fitting pointing straight down (you can just see the red silicone coupler on either side of the BOV hose) about six inches out from the compressor intake. Presumably that's got a filter on it? Definitely a strange routing.

Yeah, that looks like one of the knockoff "Type S" bypass valves, wherein nipples are available at both sides of the diaphragm.
The upper nipple is connected to the manifold post-TB, the lower nipple is connected to the manifold pre-TB, though this connection can be considered optional, to be used when it is desirable to increase the sensitivity of the unit (bypass more and sooner), which would be comparable to removing the softer of the two springs in the "Type R" style valves. The lower nipple can be left VTA if desired. |

That intake placement is one puddle away from a world of hurt. I would pull it back up several inches or find another place for it entirely. |
Why is your catch can mounted side ways?

I have the real BOV.

it requires you adding some sort of vacuum port between the IC and TB. Otherwise just run without the lower port like you have it.

I have one that is capped off. No intercooler at the moment, I have 3 laying around including a FM one that came with the car but dont like the routing on it. I want to run 2 inch piping but cant find a kit that i like.

I certainly wouldn't put the filter 3 inches off the ground like that, sounds very dangerous even if you don't ever intend to drive it when it's raining. Also, the temp of the air going into the filter matters a lot less once you've got a decent intercooler in the system. --Ian |

Down where? If you route it like that, the AFM would sit somewhere up at the top. I dunno if it'll fit or not -- A 99 MAF fits fine, but is smaller than the flapper-door thingeys.
