The second generation RX-7 still known as the "Savanna RX-7" in Japan, featured a complete restyling reminiscent of the Porsche 928. Mazda's stylists, lead by Chief Project Engineer Akio Uchiyama, actually focused more on the Porsche 944 for their inspiration in designing the FC because the new car was being styled primarily for the American market, where the majority of first generation RX-7's had been sold. This strategy was chosen after Uchiyama and others on the design team spent time in the United States studying owners of earlier RX-7's and other sports cars popular in the American market. The Porsche 944 was selling particularly well at the time and provided clues as to what sports-car enthusiasts might find compelling in future RX-7 styling and equipment. Handling was much improved, with less of the oversteer tendencies of the FB. Steering was more precise, with rack and pinion steering replacing the old recirculating ball steering of the SA. Mazda also introduced Dynamic Tracking Suspension System (DTSS)in the 2nd generation RX-7. The revised independent rear suspension incorporated special toe control hubs which were capable of introducing a limited degree of passive rear steering under cornering loads. Mazda also introduced Auto Adjusting Suspension (AAS) in the 2nd generation RX-7. The system changed damping characteristics according to the road and driving conditions. The system compensated for camber changes and provided anti-dive and anti-squat effects.Factory SpecificationsEngine

- Mazda introduced a convertible version of the RX7 in 1988 with normally aspirated and turbocharged engines.
The convertible featured a removable rigid section over the passengers and a folding textile rear section with heatable rear glass window. Power operated, lowering the top required unlatching two header catches, power lower the top halfway, exiting the car, folding down the rigid section manually, and then further power-lowering the top. Mazda introduced with the convertible the first integral windblocker, a rigid panel that folded up from behind the passenger seats to block unwanted drafts from reaching the passengers — thereby extending the driving season for the car in open mode. The convertible also featured optional headrest mounted audio speakers and a folding vinyl snap-fastened tonneau cover. The convertible assembly was precisely engineered and manufactured, and dropped into the ready body assembly as a complete unit — a first in convertible production.
In the spring of 1992, the coupe RX-7 replacement, the third generation RX-7 (FD3S) was released, however Mazda continued production of the FC3C Convertible until 12/92 as a 92 model year. The 92 Convertible was identical to the 91 versions except that a tan interior seating and door surface color option was added to the line up. Infini
3 model were produced being INFINI II, III, IV. IV being the rarest of them all.
Although Mazda had produced earlier versions of the Infini, the IV was the first to bump up power and the suspension.
Stripped of all Savanna and RX-7 identification, this was the last limited edition ultra high performance version of the 2nd-generation RX-7. A factory hot rod, the Infini IV was lightened (to 2770 lb.), by stripping out the extras such as a sun roof, and using lighter parts including lightweight alloy bonnet and front fenders, perforated suede like material racing style seats, a smaller brake master cylinder, reducing the noise dampening material and using the 1986-1987 Sport/GS model's light weight carpet. And a red strut tower brace and a Momo 3 spoke steering wheel and Infini logo horn button.
With a revised suspension (shocks 25% stiffer, springs 10% stiffer and lowered 1") Special Pirelli designed P-Zero tires, ultra lightweight 16 inch BBS wheels and a bright red front strut brace, the handling improved to a skidpad of .91 Gs. The Infini IV (as with most 91 models) also came with the tighter steering rack from the 89-90 North American GTUs model and its engine speed sensing power steering. Molded knee Pads at the driver's door side and center console were added to help brace the driver's legs while cornering, while a "dead pedal" bar ran the length of the passengers floor.
Similar again to the US spec 1989 and 1990 GTUs the Infini IV came with the 4.3 rear end final gear (but also used a new Torsen Limited Slip Differential), and the options kept minimal with air conditioning, Infini embroidered floor mats, and a AM/FM radio the few options available (however it did come standard with a rear window wiper and power windows). Power was bumped to 215 HP (JIS), largely by changing the exhaust to a free flowing design. The Infini IV, also came with the Bronze tinted glass found in the US spec 10th Anniversary edition, and was available in one of two custom black/green metallic paint colors. Of the 600 made, the first 300 cars built on limited production runs between June - Dec 1990 were painted Mazda paint code GU (Shade Green) while the last 300 cars built starting Jan 1991 through February 1991 were paint code VQ. Of these last 300, 20 of them where sent to MazdaSpeed for the MazdaSpeed Package which only did minor cosmetic changes like MazdaSpeed embroidered seats, MazdaSpeed steering wheel and shift knob.
0-60 performance was reported at 6.5 seconds and the quarter mile time dropped to 14.9 seconds, with Infini specific brake pads helping make an impressively matching braking force of 60-0 in 141 ft (8 feet less than the standard RX-7 Turbo) despite the ABS being deleted off of the car at time of production.

- ABS, sunroof and cruise control standard, headlight washer jets(option), LSD (option).Sports
- NON-TURBO.Australian Motors Mazda released a limited run of 250 'Sports' model Series 4 RX-7's; each with no power steering, power windows or rear wiper as an attempt to reduce the weight of the car.Series 4 and Series 5 Difference's Interior:
The Dash - There is a very slight difference between S4 and S5 dashes in the way they fit to the existing fittings, these can be adjusted to fit however for fairly cheaply.
Series 5 Rx7's have the full circle water temp, boost, oil and fuel gauges; s4's have the half moon style.
Dash Gauge Cluster - If you want to upgrade say for example from a S4 cluster to a S5 cluster it is possible but you will need to change the loom or adjust the wiring in order to get all gauges to work correctly. (May Not be required for some aftermarket ECU's)
Idiot Cluster - The idiot cluster if it needs to be updated will not fit correctly and is quite expensive to fit.
Front Seats - are different shape but rails are the same.
- Cruise control including control unit and switch (not sure if interchangeable)
- All the switches and knobs on the cluster surround are slightly different as well as the cluster surround itself.(interchangeable)
-The radio heater surround and gear stick surround different.(interchangeable)
- Door trims and window switches (interchangeable) - Inner door skins (trim) are different on s5, as speakers are mounted.
- Logicon units have different symbols
- Idiot light lens is at a different angle on OZ spec s4s to all other models (except some us models)
- Bezel for idiot lens changes to suit above
- Shift knob redesign along with steering and facias

- Factory bodykit differences (Series 5 have side skirts, etc)
- Rear wings are different
- On an FC Rx7 from an s4 non-turbo to an s5 turbo the front bar supports (front and rear reos/reinforcements) are identical. If your after market body kit doesn’t fit it could be the kit it self, previous damage to the car or just the person trying to fit it.
- Front reinforcement bar for s5 has provisions for mounting fog lamp assemblies
- s5 Aus delivery has different side indicators imports don’t (interchangeable with slight mods)
- s5 guards have bigger lip to bolt on side skirts (interchangeable)

- same as above for 'no rear wiper' model
- s4 bonnets are mild steel, some s5 bonnets are aluminium and some mild steel
- rims differ between series/model
- 88 model Aus spec s4 has this middle brake light as well (the one near the key hole for the boot) Mechanical:
Series 4 NA: 146 HP @ 6500 RPM w/ 138 Ft/lb @ 3500 RPM
Series 4 Turbo: 182 HP @ 6500 RPM w/ 183 Ft/lb @ 3500 RPM

Turbo waste gate/manifold differ between series, series 5 turbine housing is larger and has two waste gate holes instead of 1 on the s4
s4 has mechanical oil metering pump and s5 has electric pump with stepper motor
Intercooler apparently s5 has a couple of extra rows of cores? (interchangeable)
Radiator and water pump are different (interchangeable with slight mods) Driveline:
Although they may seem similar, there are some slight differences between the factory Differentials. Both are LSD with the same spines.
Series 4: clutch-type LSD's
Series 5: viscous-type LSD's
S4 Manual: 4.1
S4 Auto: 3.909
S5 Manual: 4.1
S5 NA Manual: 4.1 (4.3 LSD)
JAPSPEC SER 5 turbo FC3C 90 build--convertible-- has an open diff as standard not an LSD.
Gear box different ratios between the two (interchangeable) Suspension/Brakes:
- ABS standard on Aus delivery s5 but not on all imports.
- Apparently sway bar ends are different?(interchangeable)
- The brake and clutch master cylinder between S4 and S5 are the same, however the non-abs model are different to the abs equipped model and are NOT INTERCHANGIBLE unless you have both matching booster and master cyclinder along with matching lines (or modify existing brake lines)
- steering rack ratios differ
- manual steering rack + windows and mirrors only released on early base model s4s Electrics:
- Alternators are different betwwen s4 and s5
- ECU and wiring loom not interchangeable including air flow meter, injectors and various other sensors.(NOT interchangeable) Other: - VIN Differences
It's possible to find out more information about the FC series you have or are looking to buy by cross-referencing the VIN number with the Make and Model plate to make sure it's correct.
Take a look at the 10th digit in the VIN and reference the info below.
The 8th digit of the VIN is for engine type
1: N/A Model
2: Turbo Model
You can tell the difference between an Aus delivered and a Jap import by looking at the chassis code.
Aus Deliver: FC10
Jap Import: FC3S
