323 GTX of Al Durham
323 GTX of Al Durham
The original Mazda 323 was a reliable entry level car. When the GTX came out, it had four wheel drive, an electronic gear lock for low traction, and a turbocharger that made 50 more HP than stock 323. The GTX cost nearly twice as much as a stock 323 and only 1200 were ever imported. Take the mild mannered 1600 cc 323 GTX with the coefficient of drag of a parachute, install a full cage, programmable fuel injection, variable cam timing, and water injection and make a rally car. No, wait, I’ve got it, let’ take the same car install a turbo the size of Texas, put 3 fire systems and parachute then run almost 180 mph on the Bonneville salt flats.
Mazda saw an opportunity for the 323 GTX in the 1.5 liter formula. A racing shop in Greenville, SC built 6, 323 GTX rally cars. I don’t know the rally result for this car but somewhere along the line the one I own was converted to a Land Speed Record Car. The car came with a full interior but also a full cage. The driver’s seat became a Kirkey. A very large turbo for high end performance was added (unbelievable turbo lag—unbelievable acceleration when it finally hit). The variable valve timing set up plus water injection and 25 lbs. of boost produced 450-500 hp out of 1500 ccs. The smaller 1488 cc engine ran 154 mph and the larger 1600 ran 177.301 at Bonneville. The car also set records in the Eastern Timing association years ago with the idea of making it a rainy day road race track event car. I ran it at VIR raceway. One thing I forgot is that rally driver only uses brakes to slow the car sideways and to stop at the end of the session. Road racers need more even in the rain. Coming on to the straight, there were faster cars behind me as I had the foot to the floor trying to build boost. I would always get the move over flag but would try to wave it off because when boost finally hit it almost lit up four racing slicks – funny but not too drivable. I was also the only road race car on the track with a parachute on the back bumper.
It was apparent, that the T4 turbo had to go, the car has the race motor with a knife edge billet crank, I beam connecting rods, variable valve timing, racing pads, lowered suspension with coil overs and a 944 turbo that spins up fast to 8500. There is a programmable fuel system for the fuel injection. Ironically by lowering the boost to 15 lbs., reducing the advance and making a smaller turbo has produced an ultimate street sleeper (full cage gives some away) with a Dr. Jeckyll and Mr.Hyde personality. The car has full liquid filled auto-meter gauges, variable boost, full fire system, water injection and is completely street legal. The car still has its official SCTA number for Bonneville and tech stickers.
The car has lots of personality, a real good sound above 7K rpm and lots of boost and traction. Probably the best use of the car is making Mazda’s reputation against turbo civics or WRX’s. The car is drivable as is but it could be put back to high boost but this time with no turbo lag. For right now, it attracts lookers and interest wherever it goes and people love the idea of seeing a Bonneville record car first hand. I probably won’t do rainy day road racing but is drivable enough to do it if I want. Right now it is fun to have one of the most unique low production Mazda’s in the world (only 8K miles).
