It is a top-mount v-mount using the stock NB nose. Minimal cutting required for the body, and the framework was easy to fab as well. It is all boxed in (splitter and undertray) so all of the flow coming in the nose is forced through the radiator and IC (and a/c condenser).
Come on with the pics!! Although, Sav might prefer in your own thread so you don't hijack his. His/your call.

Sav -

If you have access to a welder, weld bosses on tabs onto the side panels, after you have tapped them. Then bolt the lower plates into place with a rubber gasket between the pieces.

Sav, I bought some extreme weather ducting tape at home depot today, might wanna look into it. I'm using it to tape some insulation to the tranny tunnel to control heat, but you might wanna think about sealing all your ducting with it. Not only will it hold up to the heat, but it'll blend in and really create an air tightish seal. Freaking stuff was $20 a roll though, good to 260*

I will look into the tape, and I like the welded boss idea. I think I can just cut the metal with the boss attached and then bend it to avoid the welding, as well. The plan is to use rivets to assemble it all.

Savington's set-up is fine. "We're" running a similar set-up on Matt's car and with the "splitter panel" between the FMIC and radiator at 1" enough air goes to the radiator that it never went above 200* at WS in 101* heat...and that car makes well into 400whp.

Direct link to tape since it's on the 2nd page of that thread. I'll be picking up a roll tonight!

Good stuff. That's actual duct tape used on real mechanical ducts. Inspectors won't allow the stuff that's called duct tape on ducts anymore since it dries up & peels off after a couple of years.

Ah, that stuff. I had a roll for a long time, just finished it off. It's great for covering holes in the firewall, stuff like that. I always just called it metal tape

Anyone have a link to a cheaper price? It was $20, and I was worried I wouldn't find a cheaper price and just have to go back. I needed to get it done anyways.

I'm considering cutting a hole in my bumper between the blinkers to feed by oil cooler, so I am currently reading through https://www.miataturbo.net/forum/t14760-2/ thread. I'm slightly discouraged by people saying "it won't work" but from what I can tell, they're saying it won't improve cooling for the radiator and intercooler proportionally to the size of the hole in the bumper. The one thing it will do for me it give air to my oil cooler, which currently has none. Anyways, I just thought I'd share one of Sav's old quotes, I find it funny considering the work he's now documenting in this thread.
