RX-3

March of 1972, the RX-3 was discharged in Australia – seven months when Mazda Japan had launched the RX-3 and also the Familia/808/818 (1600cc/1800cc) domestically.

With the addition of 3 new body designs, the rotary line up currently totalled 9 selections internationally. Following the ‘peoples rotary’ theory, the primary rotary auto was created offered in Japan and within the America. The Australian market (and New Zealand) was less lucky. Not solely missing out on the wagon however the 130hp 12A. Australian-model RX-3s came in 2 bodies – the Deluxe sedan and also the Super Deluxe machine.

Equipment variations between the RX-3 Deluxe sedan and also the Super Deluxe machine were several. The machine carried associate nonmandatory body stripe, clock, rear defogger and also the centre console/high rest and foldaway steering column. All Series one RX-3s came with the 982cc 10A. The manual sedan price AUS$3299 (3-speed transmission system was a $341 option) and also the machine AUS$3479. scrutiny the machine in value, Mazda priced the RX-3 against cars just like the 190-hp Holden Torana GTR XU-1 ($3455), the 144-hp Ford Capri GT V6 ($3490), and also the 218-hp valorous RT Charger ($3395). as luck would have it value did not play an awesome role in RX-3 sales – the rotary engine was Mazda’s main point.

Performance-wise the 10A RX-3 wasn’t able to match the RX-2 with 12A. With a power-to-weight quantitative relation of ten.9 kilogram per kW compared to the RX-2’s nine.9 kilogram per kW, the RX-3 was slower. denizen driving journalists did well to push seventeen.6 second quarters at 76mph out of the lighter sedan (16.3 for the RX-2).

In late 1973, Mazda discharged the Series two in Japan. outwardly the complete forepart flat solid was revamped and a distinct set of taillights with twin brake lights were enclosed (commonly called savannah taillights in Australia). The Series two RX-3 hit Australia in March of ’74 hopped-up by the 12A single dizzy (12B). The Series two was slower than the one0A Series 1 down the 440 yards even with the 1146cc 12A’s larger capability and fifteen % a lot of power. The Rotary Engine opposed Pollution System (REAPS) hurt torsion. As a result, the Series two was slow off the mark however had a far better prime speed. The loss of torsion and a 44-kilo weight increase slowed the series two to a seventeen.8 second 440 yards. further exterior colours for the Series two like green and Alexandria Gold additional attractiveness. Interior amendments were minor and enclosed a change from the kilometers per hour/mph meter to a two hundred kilometers per hour meter (180 kph for the 808), associate exhaust overheat lightweight, a fifty amp/hour meter gauge (up from 30ah) and style changes to the trims and seat belts. Notably the nondirectional antenna was increased by a twin post (rather than single) style. The ’74 model unbroken the 3 spoke plastic wood grain steering wheel; the ’75 received a faux animal skin wheel with slots dig its 3 spokes.

Mazda Motors Pty Ltd operated throughout Victoria, Tasmania and southern office – the remainder of Australia was lined by freelance distributors. Documented records show the peak of the rotary-powered era was between 1972 and 1975. throughout the commercial enterprise term of could ’73 to Apr ’74 Mazda Motors sold-out 2866 rotary hopped-up vehicles (including RX-2, three and 4) a complete of forty % of its overall vehicle sales. At identical time Mazda Japan was pumping out 5000 RX-3’s per month, with a lot of then half these being coupes with the balance split between the sedan and also the wagon.

In March 1976 the RX-3 was formally off from the Australian lineup. the worth had crept up to AUS$4525 for the machine, that was cheaper than the RX-4 machine however still costly by comparison with similar cars. Remaining RX-3’s lingered on the dealer floors well when the March time limit.

In 1976 the Series three RX-3 was discharged in America and Japan however not Australia or New Seeland. There weren’t as several changes this point around, however the few created were vital. The front wore a brand new lower spoiler-type lip, the gimmick rotor badges were replaced with a straightforward Mazda badge on the grille.

Of all the pre-RX-7 rotary vehicles Mazda engineered (930,000 in total), the RX-3 was far and away the foremost widespread. Of all the RX-3’s engineered, the machine exceeded fifty % of total sales – all facts that influenced the planning profile of the RX-7.

On race tracks, the RX-3 proven extremely competitive from its introduction in 1971. In Japan the RX-3 won the phaeton title in ’72, ’73, ’75, ’76 and ’77. In could of 1976 the RX-3 won its a centesimal Japanese domestic race. To celebrate, Mazda made ceremonial specials (tricked up AP-GT). The RX-3 conjointly won the japanese automobile race in ’72, ’73, ’75, ’76 and ’78. Locally, the RX-3 did fairly well. CAMS’ backward read towards the rotary barred any variety of porting to the engine; but, the RX-3 knocked up variety of phaeton category wins and often embarrassed V8-powered opposition. The RX-3 scored category wins at Bathurst in 1974, ’75 and ’79, and in 1975 Don Netherlands took his RX-3 machine to fifth outright. In 1977 associate RX-3 managed seventh outright.
For the 1979 race, CAMS finally allowed bridge porting. It wasn’t till the early-80s once clever lobbying towards CAMS allowed peripheral porting of the 12A RX-7.

When searching for real RX-3, look fastidiously. begin with the chassis number: the Series one ID starts with S102A and also the Series two with S124A. The 1300 808 ID range starts with STC and also the 1600 model with SN3A. As mentioned, the RX-3 was born in ’76 but the 808 continuing nonparallel three type till 1978. There square measure quite an few RX-808’s out there, some with range jobs. as luck would have it there square measure many ways that to acknowledge a well-disguised RX-808.

The Series one RX-3 features a rear registration code frame – the 808 does not. The 1300cc 808’s have a really tiny diff center compared to the quality RX-3 diff center; but, the SN3A diff is RX-3 sized. All RX-3 rear bumpers have sq. reflectors and also the Series two front bumper features a cut-out for oil cooler air flow. The 808 model bumpers do not have either. All RX-3 fuel tanks square measure sealed with the letter L and carry sixty litres. The 808 has associate S stamp and holds forty five litres.

The Series two RX-3 can have emission management relays in its ‘computer box’. Engine bay wiring can have a choke management associated an ignition relay or a minimum of its correct unused plug and also the harness are going to be usually thicker than the 808’s.

The best identifying attribute of the bunch is that the exhaust overheat thermosensor. set within the right corner of the boot close to the shock tower, this device would short out and illuminate the dash-mounted lightweight once the REAPS rear muffler het ‘beyond safe limits’. If the device is not there, explore for the mounting holes and/or the introduce the wiring loom.
