Rx7 how many miles
Making use of a pair of sequential turbos with one designed to deliver low-rpm boost and the other coming on around rpm , the engine was advertised as delivering horsepower at rpm and lb-ft of torque at rpm, with an rpm redline.
These numbers were enough to launch the RX-7 to 60 mph from a standing start in just five seconds, thanks in large part to its pleasingly-low pounds of curb weight. There have been entire volumes written about the saga of maintaining, modifying, and otherwise living with the high-tech marvel that is the 13B-REW, and nearly as much hand-wringing about its reliability.
Anything lower than 85 psi and you could be looking at a rebuild in the near future. Poor compression can often be linked to either a leaking side seal or broken apex seal.
A third option, which is what I run on my own personal cars, is to connect the metering pump to a secondary tank filled with two-stroke oil. This allows me to run a high zinc-content synthetic oil from Brad Penn without having to worry about the combustion issue. Shorter intervals than the factory mile recommendation are better, because it means that the previous owner was more vigilant about not just oil condition, but oil level, which is crucial for the RX Most recommendations are for oil changes in the to mile range, with the latter representing the outside edge.
Some owners are completely unaware that the engine burns oil at all, which makes checking those records that much more important. Heat is also the enemy of FD reliability, and it can manifest itself in a number of ways when inspecting the 13B. I also replaced all of my coolant hoses connecting the radiator, the heater, and the turbo at the same time. These cars are 25 years old at this point, and the harness is notorious for drying out and becoming brittle to the point where it can cause intermittent electrical problems.
General engine-specific test drive advice for the FD RX-7 includes hooking up a boost gauge to the intake manifold and have a passenger verify that the turbos are healthy. Due to their reliability and sporting qualities, low-mileage cars are very rare, which explains the price variance. But , mile cars still promise lengthy service, and wrecking yards will provide plentiful spares. However NOS parts are more difficult; there are few new cases for 12A carbureted engines, and the much rarer 13B engine cases are practically non-existent.

Filming today with something special thanks to lbilimited. Jean-Pierre Derdeyn of rotary-specialist shop Derwin Performance told Hagerty that rotary engines can last for , miles or more without issue if maintained correctly. This creates flooding, which can cause the oil on the rotary walls to thin, causing excessive seal wear.
In addition, revving a Mazda RX8 close to redline is actually beneficial. RX8 owner forum users report this is to help burn off excess carbon buildup, which can otherwise internal engine damage and corrosion.
But perhaps the most important difference between a piston and a rotary engine is with oil consumption. Instead, Derdeyn recommends using zinc-heavy conventional oil; some owners even modify their cars to accept two-stroke oil. All the better if it has the 13B engine, with the extensive aftermarket they are a fun, affordable option compared to the 3rd generation cars that demand a premium or are basket cases and the slightly heavier 2nd generation cars that are arguably less attractive.
