If not, then you need to consider alternatives engine options, even buying another rotary and have it waiting in the wings. Avid Formula 1 fan and motorcyclist, I enjoy chocolate chip cookie dough ice cream and long rides to the beach.
Mazda RX7s are one of the most popular enthusiast cars. Looking at RX7s for sale? Common Modifications for an RX-7 The car is small and light, but you can make it lighter. Best Used Cars. The engine was unusual for its use of twin sequential turbos. Indeed, it was amongst the first of its kind. The concept was simple, the first turbo boosting from rpm, with exhaust gases then fed directly from it into the second, identically sized, turbo to further reduce lag.
It was an effective, if complex system that relied on precise electronic control of boost pressures to work seamlessly. In Japan it was tuned to deliver bhp, but in Europe it developed a slightly softer bhp at rpm, with lb ft of torque at rpm. That still put it on a par with the four-cylinder , but some way short of the more potent six-cylinder M3, Supra and ZX. Nevertheless, the kg RX-7 remained an appealing and rapid machine, capable of hitting 60mph from a standstill in 5.
Just of these curvy coupes were officially imported to the UK, and this is one of them. The Fast and Furious movie franchise has plenty to answer for. Like all cars of this era, the RX-7 seems so small and compact.
The door handle is positioned unusually high, up above the waistline and nestled against the B-pillar. You open the door expecting the glass to be frameless, but instead you find a heavy black surround framing the side-glass lenses like a pair of thick-rimmed spectacles. The instruments are simple but really quite handsome, with a bold typeface, a speedo that reads to mph and a tacho that reads round to rpm, even though the red line itself starts at an altogether more modest rpm.
Gauges for oil pressure, oil temperature and fuel level sit to the left of the tacho to complete a proudly analogue binnacle. The view though the windscreen is dominated by curves, the rising line of each extremity swooping up towards you while each door mirror captures a reflection of the long arc of the door tops that flow into the rear wheelarches. Before it, Mazda had made the Cosmo sports car , as well as a whole line of other rotary-powered cars.
Rotary engines are lighter, smoother, and mechanically simpler than piston ones. They can also make more power per liter, which meant they could be more compact. This would continue for the second-gen FC and third-gen FD. These later gens, though, added even more performance. The FC RX7 came with a 1. The later Turbo II model had an updated turbocharger design and air-to-air intercooler and made hp.
The smaller one spooled quickly, to boost low-RPM torque. Is it hard to rebuild an engine? Rebuilding engines is not HARD work, it is fine work with much measuring, machining, mating, matching and such. Special tools are needed to clean the block and heads, mill their mating surfaces flat, bore the cylinders and line bore the main bearing and cam bearing mounts.
