The Mazda RX-7 is a front/mid-engine, rear-wheel-drive rotary engine powered sports car that was manufactured and marketed by Mazda from 1978 to 2002 across three generations, all of which made use of a compact, lightweight Wankel rotary engine. ... This featured a sequentially turbocharged 13B REW engine.
The Mk4 Supra was also powered by a 3.0-liter six-cylinder engine, but in its base form it was naturally aspirated and produced just 220 hp and 210 lb-ft of torque. The iconic 2JZ 3.0-liter engine arrived later, producing 320 hp and 315 lb-ft of torque.
Under the hood are twin ceramic intercooled turbochargers, which effectively eliminate turbo-lag. The RB26DETT in-line, 2568cc six-cylinder engine retains the 280PS at 6,800 rpm of the R33 it replaced. It also has better power delivery and more torque than it predecessor.
