Does anyone happen to know the size of these 2 fittings? Are they 1/8" NPT?

^^update, they're not 1/8" NPT
I'm thinking they're M10-1.0 bolt size... not 100% sure though, since the only parts store within walking distance didn't carry that size.
Any feedback would be greatly appreciated. I'm either going to plug those holes or use different size vacuum fittings in them.

Good info in here. I will add that I used the OBX rails that came with my ITB kit....mostly because I had them onhand and knew I would be fabricating adapters anyway.

You can see the small adapters I made for the rails, as well as the 1" spacer welded to the .500" plate I had previously welded to the plenum. My throttle cable bracket is anchored to the lower boss on the plenum and the cable runs under the coolant crossover, up to the TB. It's a 70mm Ford unit with no IACV. This setup has no idle function aside from a programmed fuel/spark cut on the ECU side (aka GpN type).

Also note that most aftermarket rails will interfere with the oil fill tube. This will need addressed.

They are 1/8 BSP from the factory, but I chased those threads with a 1/8 NPT tap and used 1/8" NPT fittings (Thats my manifold pic).

Thank you so much for the info! I think I'll be ordering a 1/8 NPT tap as well.

I just want to bump this up for people. We should keep this thread alive for issues, solutions and ideas.

Seems to me that the biggest hurdles are DBC throttle body issues, and clearing issues when used with AVCS heads.

^^^ Zero drift sports makes a rail, contact ASF to get them. They have been installed on AVCS and DBW cars.

I have a 2011 STI and a 2.5 NA longrunner intake manifold. I used outfront motorsports fuel rails and 16mm phonolic spacers. (can go bigger if you want)

mine is NOT reversed, its a DD so I can keep A/C

you don't need to lose the A/C if you go rotated manifold, you'll need 8mm-12mm phenolic spacer and notch the alternator bracket to allow for it to sit lower, then you'll clear it with your cool charge piping.

With 8 to 12mm spacers the rails wont clear the head vent tubes. At least they didnt with the 2.0 head vent tubes. I needed 19mm.

Does anyone have that picture of all the holes and fittings and stuff we can shave off the manifold? Trying to save some money and do it myself.

I spent the time doing it and grinding it down to make it ready for powder coat, it was a lot of time with a carbide burr doing the EGR tube alone, if I could go back and do it all over again, I would send it to someone to do it

My good friend owns a metal polishing business. He shaved and polised my long runner NA manifold.

Been working on mine myself, regret it greatly lmao.

Deciding to have someone finish it, and have it ported/honed before powdercoat. Or just have it powdercoated once I am done doing it myself. Stock heads/motor I won't see gains so I'm not sure

I contacted Outfront a few days ago. As of then, they have the rails. $160.00 is what I was told. Does not include anything except for the rails.

For those of you who are running this mani in the non-reversed mounting position, how much room do you have between the throttle body and the firewall?
