History
The Mazda RX-7 SP was designed to compete in production car racing -
particularly endurance racing. The Series 6 RX-7 had won the Bathurst
12 hour production car endurance race in 1992, 1993 and 1994. In 1995,
both BMW and Porsche released limited edition race special vehicles
(BMW M3R and Porsche 911 RSCS) which threatened to take the glory form
Mazda. Mazda Motorsport (Australia) responded by making modifications
to the S6 RX-7 to produce the RX-7 SP. Homologation rules for
production car racing required 25 road-going models to be produced. The
RX-7 SP was only produced in 1995, and only here in Australia.
The SP debuted at Calder in the GT Production category supporting the 2
litre series on 11-13 May and driven by Gary Waldon. This same car,
driven by John Bowe and Dick Johnson, won the 12 hour event held that
year at Eastern Creek. The RX-7 SP went on to compete in other
production car events including Targa Tasmania and the Poolrite 3 hour
"Showroom Showdown". It claimed pole in the 1998 3 hour event and won
the race in 1999 at the hands of Terry Bosnjak and Mark Williamson.
Eastern Creek, 1995
Mazda Motorsport entered 2 SP's at the Eastern Creek 12 hour - one
white and one black. Both cars were sponsored by MMM. The white car
driven by Bowe/Johnson won, the black car of Skaife/Waldon finished
4th. Allan Grice who was a reserve driver badly crashed the black car
during practise on Saturday. The car was brand new and suffered severe
damaage both front and rear. An amazing effort by the team mechanics
repaired the car for the race, albeit in average looking condition.
A 3rd SP at Eastern Creek was the privately entered Bosnjak/Jones car
that may have even led the race at one stage but finished early.
Speculation suggests that it was an ex Mazda car from the previous
12hour races privately upgraded SP spec.
The race result was protested by the Porsche team due to what they
claimed was a safety car error that gave the white car an advantage
early in the race, but the protest was not successful. Additional
controversy abounded over the Mazda team's use of chilled fuel,
allowing denser fuel to be filled into the tank.
Thanks to Greg E for much of this race information.
Production Numbers
The exact number of SPs produced by Mazda is vague and widely argued.
It is known that an initial pre-race batch of 25 road cars was
produced, with a minimum of 10 required to meet homologation rules to
allow the SP to race. Some view these as the "original" SPs. It is
widely, though not universally, accepted that Mazda built another 10
SPs after its racing success at Eastern Creek. Different sources from
Mazda Australia provide conflicting information on this. RICE RACING
has provided the following letter from Mazda, dated prior to the
Eastern Creek event and hence prior to any plans for a possible further
10 cars.
As many as 4 SPs were built as race cars, though only 2 were used in
the Eastern Creek race. Conflicting information abounds over whether
these cars were drawn from the initial batch of 25, or if they were in
addition to those 25. Terry Bosnjak commissioned the 1994 Bathurst
winning Series 6 to be upgraded to SP specification, though this likely
does not count as one of the "official" SP builds. There is also
speculation that 2 cars were used as press test mules, though it is
unclear if these were drawn from the initial 15 or built in addition to
them.
Ian Pollard, responsible for fabricating parts for the SP, is quoted as saying:

Performance
The following figures are for a completely stock RX-7 SP on street tyres.
Tested by Motor Magazine, June 1995
0-100: 6.07s
400m: 13.98 @ 100.66mph
The cars are fitted from factory with a reprogrammed ECU
Modified Performance
With exhaust restrictions removed and boost increased to 13psi, 1/4 mile times are typically in the high 12s/low 13s.

The SP list you see on this forum and on a couple of others was
originally consolidated by myself using the Mazda identification
program that I use everyday to find out trim codes,paint codes,warranty
expiry dates,ect.
The process involved was basically all chassis numbers in the series of
JM0FD1033......were punched in and if it came up as an SP then it was
recorded.
