TC Design in Campbell, CA is doing virtually all the fab work on the car. It'll be half done when it gets here. John has to bolt everything on and wire it. In the past we did most of the light fab here, like building sheet metal dashes and whatnot. In the interest of saving time on the build and getting much finer quality fab work, we asked TC to basically build the car for us.
Still to come, wing mounts, front ducting, front fender ducts, brake ducts, ducts in rear bulkhead feeding assfans, intercooler piping, 3" exhaust and other sexybits
A mentioned earlier in this thread, I wanted something more like an FIA cage given the speed potential of this car.
Primary reason for the Tilton pedals was the need to eliminate the booster to get a straight shot from the dash bar/door hoop to the shock tower. We ordered the cheap Tiltons
Dash. Canted towards driver with enough room for my long fingers not to swipe switches accidentally like I do in other peoples Miatas
Doorbars and floorboard detail
The doorbars will also get a big gusset plate tying them together in the "X". Hard to see in this pic but the doorbar tubes point out from the car centerline so the crossover point is like the top of a pyramid.
Oil cooler in the RF fender under headlight. We debated on whether to allow rear mount radiators. Decided it would be too costly and complex for most weekend warriors to do on their own. IC and rad will be stacked with allofit engine bay venting in the hood and inner fenders.
Driver seat is an HTE-R 400. Fits well in a Miata for small to medium drivers. Big guys need not apply.
Pax seat is a wider RSPT which has been superceded by the RSPT-2. I don't recall dimensions, go to OMP site for more info.
Cage was built to allow both seats to get as close to bulkhead as possible. Driver seat is slammed all the way back. It'll actually be too far back for me, which we can compensate for with the adjustable pedals.
Yarp. Ducts not built yet. They/it will be built into tops of rear qtr panel(s).
What about getting the air from the rear wheelwells instead? It's well-known that the front wheelwells are a high pressure area... I've always assumed that the same is true for the rear wheelwells. They're almost definitely higher pressure than the license plate area. Just hole-saw a 3" hole in the inner fender sheetmetal, weld a tube in the hole, and run a short piece of hose to each cooler.

Perhaps. To validate might require some field testing that we don't have time for. The fans will generate a pressure differential even if the inlet is at atmo. So we don't need an extreme high pressure source.

A little thread drift, so forgive me. Define "big guys", like 6' 200lb 34" waist guys are too big or much bigger than that? Currently eye-balling that exact seat for my future PTE/ST6/SPM/whereever-the-****-it-lands car.

Visit the seat mfr website for dimensions. I'm very skinny (6-3, 160lb bicycle racer) so any normal American dude is "big" to me. The HTE-R 400 fits in a cage Miata better than any other FISA seat I have seen. The 400 refers to the wing width, 400mm where most seats are 560-620mm. That's right where the door hoop/hardtop is. Too wide a set and you have to cut part of the wing off and compromise seat position and comfort. AFAIK, no other FIA seat is anywhere near that narrow.
I'm a sticker for getting the seat in the most comfortable and safe position while remaining centered behind the center of the steering wheel. This goes a long way to reducing driver fatigue in enduros. Crusher had a Cobra Evo with a TC cage build around the seat. Every driver that got in it said it was either the most comfortable Miata or most comfortable race car they had ever been in. For me, the seat was a bit too close to the pedals but I mounted it there so normal height drivers could fit in.
Te steering column is angled. In my cars I always have a very long extension on the hub adapter so the wheel is maybe 4-5" further back than OEM. Driver weight further back also helps weight distribution and is safer. The centerline of the wheel and the spot where the shaft attaches to to the dash bar are often a good 1/2" offset since the shaft is angled. I put my seats behind the center of the wheel, not where the shaft attaches to to the dash bar. With a wide seat, that's difficult. I have also driven Miatas that had their seat angled a few degrees to fit the tub and also radically offset from the wheel centerline. I found those excruciating to drive.
edit: I sat in/owned OMP seats other than the HTE-R 400 before buying it. Compared data on OMP's site so I could estimate how I would fit in it. IOW, sit in any OMP seat that you can still find official dimensions for and perhaps extrapolate fit into the HTE-R 400.

I'm 6'1 210 34" waist with a long torso and I fit fine in the HTE-R 400. I got tired of trying to find one to sit in and finally just said **** it and ordered one. It's really comfy and fits me really well, but it still puts my head too close to the roof. I'm selling it and going back to my Tillett.
Emilio is right... HTE-R 400 fits the miata better than any other head restraint seat I've tried, and I've tried a lot.

You lost man points by quoting the pics BTW
Awesome, thanks for the info. Lol @ quoting pics. I rushed the comment on the phone, I'll fix.

Sweet, just a tad bigger than my dimensions. I shall continue to stare at the order button for the HTE-R 400.
We used whatever I/C piping diameter TSE told us to use. We'll build an air deflector for the top of the rad. I/C mounting position dictated by airflow to rad, which we wanted to try to keep in stock location. If it doesn't work, we'll try something else.
For the health of the class, I want whatever we come up with to be as easy to copy as possible. Other than high quality fab work, the basic config if pretty standard.
Also, I/C is frickin heavy. So so we stuck it low and as far back as possible with out obstructing airflow to rad. Ducting will allow airflow underneath I/C to rad.
