I was going to ask,”did AU models receive detuned engines?”
the auction site listing noted these changes
A different intercooler, modified exhaust and new ECU resulted in a substantial increase in power (up to 204 kW) and torque (357 Nm), while other changes included bigger brakes, special 17-inch alloy wheels, a larger 110-litre carbon fuel cell and 4.3:1 ratio rear diff. A significant weight reduction was achieved by using Recaro race seats, lightweight bonnet, carbon-fibre nose and front spoiler – in all there were some 120 modifications over the standard car, the appearance enhanced by the dramatic rear wing.
Beautiful. Am I wrong for wishing it were Montego Blue?
Also, the SP had a mini-battery to make room for the larger IC, and did not come with a battery cover
So, nothing seems missing, here
Also the s6 FD was quoted at 255bhp, so 273 is definitely up
Number made is wrong, but you wouldn't expect great accuracy in a sales pitch.

Might be in the ausrotary link too, but according to one of the guys involved, they had some tech from Mazda Jp tweaking the nominally stock ecus in the race cars, which would make a few more shetlands over the production run cars. As the car was designed to hopefully run 12hrs and not going to need topping up every 1/2hr, it wasn't going to be a startling number.

I would think it was mostly reliability stuff. Cooling, oiling, brakes, and so on...
OTOH, what modifications actually required building a homologation cars to begin with?
Did this particular race have extremely tight rules?
Vince Tesoriero who was a production motorcycle road racing promoter (and MX) for a few decades, thought something similar would turn to rivers of gold using the same formula with revived 12hr car races - original ones at Bathurst were strictly production vehicles with safety modifications. Too long ago to remember now what changed, might have been with increased Cams involvement when the track hire got too expensive (a SCCA equivalent) and entrants dwindled or manufacturer pressure, specials were then allowed, minimum 25 for things made/modified locally, I think 250 or 500 min for cars made offshore?
Every part had to be supposedly off the shelf. Not unknown for nitpicking scrutineers back then to ping people for not meeting homologation docs, now half of them can barely turn a screwdriver.
Mazda had previously beat Porsche for the last three years with completely normal production RX-7s (safety gear added), so they didnt really have to go all out with the SP homologation cars.
To beat the new 1995 Porsche 993 911 Carerra RS CS version Mazda included some of these mods that I know of on the RX-7 SP version.
"Carbonman" carbon fiber-
Larger gas tank
Front bumper skin
wing
Airbox/air pipes
IC duct
"SMB" 3" turbo back exhaust
Uprated stock mount intercooler
17" BBS wheels w/ kangaroo center caps
Kangaroo stickers
_____
On the race SPs consumables and safety pieces were open (free from homologation clause) so-
Bigger brake disks
Endless brake pads
?Shocks?
Recaro SP-A race seats
Cage
Quick fill system for gas tank
Fire supression
Semislick tires
Some say larger SP turbos and ROM tuned ECU on the race cars... others say SP turbos were just dynamic seals instead of stock carbon compressor seals.
Nice, but at 40k miles the price is a bit steep (from the article: estimated winning bid of $120,000- $150,000 Australian Dollars (approximately $85,000-$105,000)). I get that it is a special edition and 1 of 29, but still...

considering the rarity of those factory parts compared to how much commonly available Mazdaspeed parts now sell for, I think you might have come up a bit shy on the value.
