I have not done a lot of research in the 5 lug conversion but if I remember correctly the s2000 and the 88-91 RX7 have a very similar rear. I am not 100% but I believe you would be able to run the 88-91 rx7 axles if you go the rout of the rx7 spindles. They are the same length of the miata and have the same spline count as a 1.8l rear and I think the S2k has the same splines as well. I will see if I can find the info from before. I have the RX7 turbo II rear and it was either that or the S2K rear, so I did do a good bit of research into it. Good luck with the swap I am looking forward to seeing how it comes out. Also look into modifying the older Ford Thunderbird Turbo Coupe spindles for a good lug pattern they did not look that hard to modify in.

Thank you, okay,there are some 4x100 17" wheels, but the widest I have seen is 7", and that just won't get it done. So if anyone knows of a good 17" wheel in 4x100 and 9 inch wide let me know. It would be nice to have a 4x100 wheel choice.

I will look into it, but I like the idea of being able to pick up a new wheel on short notice if needed. Also, even though I don't plan on tracking the car, it would be nice to have a spare set with track rubber if I want.

Also did you look into Diamond racing wheels I belive they make a 15X10 but they are steel. They look good but I know you want 17" just another option on the table.

Something like an FD hub conversion would be great, but there are strong, cheap 4 to 5 lug adapters.
Motorsport Technology is reputable & can make four 5x114.3 adapters for $360. They'd be 54.1mm hub/wheel centric 2-piece billet aluminum.
The bleh part is they add 35mm spacing... Widebody/big flares would be a must at that point.

Just a small update here. I decided that it would be a good idea to thin out the mazda engine management wires and airbag wires from the harness. What a pita. On the plus side, the quirk my car had where the ds headlight would only raise or lower it the high beams were activated, is fixed. They work like stock again.
Next on the agenda are valve retainers and keepers. The AP1 retainers have been known to crack and drop valves with over revs, without warning. The last time I checked they were good, but at only $100, it is cheap insurance to go with the AP2 retainers.
On a side note, I recently got into a dick measuring contest with a Viper SRT, 60mph roll and pulled on the guy, he guy turned out to be pretty cool. We pulled over after our run and I popped the hood for him, he broke out his phone snapped a few pics, I answered a few questions, we shook hands and parted ways. It's nice when you run into "real" car guys.
Not sure where my pics went of the wiring mess, but you have all seen harnesses pulled apart before.
On my quest for 4x100, 17x9 wheels I may be getting panasports blanks drilled. I have a buddy that is a panasport dealer and am going to talk with him about the possibility of going that route. I would talk with Emilio but the 17 inch 6ul comes with to shallow a back space.

Seen the carnage of this first hand. A customer at work has a built boosted AP1 that he over revved and blew a retainer out. Luckily the broken valve caught in the guide and didn't drop into the cylinder. All of the retainers were cracking and fracturing around the edges. The keepers on the other hand were perfectly fine. No stress fractures or anything. On the flip-side, this particular guy beats the living hell out of his car, and I wouldn't be surprised if that engine saw 12k.

One of the wheels I looked at, however, in 17's they don't come wider than 7" in 4x100
Still working on the panasport solution.
They got lucky, it is fairly straight forward procedure, and is the classic ounce of prevention being worth a pound of cure.
