Do Mazda rx8 have problems?
Engine problems The RX-8 has the unique rotary style engine, and this version of the rotary engine has proven to be highly unreliable, particularly after 60,000 miles.
Warranty companies say that Mazda have unofficially said that these engines do become unreliable and susceptible to problems at over 60,000 miles..
Why did the rx8 fail?
Shrimpy Apex Seals But the apex seals in the RX-8’s engine are thinner and poorer than the ones in the RX-7’s 13B. They are lighter so they work better at high RPM, but they pose big reliability problems.
Are Mazda rx8 turbocharged?
Nothing can be compared to the feel of a rotary engine that is turbocharged. A turbocharged Mazda RX-8 provides for higher output levels and a smooth power delivery. It will also keep the heat away from the plastics in the engine bay and from the rubber hoses. …
Why rotary engine is bad?
Due to the long and uniquely-shaped combustion chamber, thermal efficiency of the engine was relatively lower compared to piston-cylinder counterparts. This also often led to unburnt fuel leaving the exhaust (hence the tendency of rotary engines to backfire, which is obviously as awesome as it is inefficient).
Why are rx8 so unreliable?
No, it’s not just one part of the engine, it’s the whole thing, as the Renesis 1.3-liter rotary engine that powers this sports car is known to be a gas-guzzling, unreliable machine. Instead of pistons, the rotary engine uses rotors to operate, and over time, they tend to wear down.
How much does it cost to fix a rotary engine?
A proper rebuild, one that goes beyond running (120+ PSI warm compression numbers) will be north of $4000. With upgrades for power and longevity, you can expect to pay $6k. A Mazda remanufactured engine comes with new housings, irons, rotors, seals, etc for as low as $2900.
Do rotary engines need back pressure?
No, they don’t need exhaust pressure, and CERTAINLY not to keep the seals from failing. The NA stock setup for the auxiliary ports needs exhaust pressure to open them, but some aftermarket systems account for that or instead you can rig them to open via RPM switches and little motors or an air pump.
Are rotary engines hard to maintain?
Rotaries simply have a different set of rules than a piston engine. A piston engine can get away with overheating, a rotary cannot, for example. But, you can over-rev a rotary and have no ill effect, whereas a piston engine you’d be looking at major damage. Maintenance costs should be in line with a piston engined car.
Is a rotary engine better?
Simplicity: rotary engines can have as few as three main moving parts, versus more than 40+ for piston-cylinder based engines. Fewer moving parts typically leads to better reliability. No reciprocating mass: this allows rotary engines to rev high, and also run very smoothly.
Will rx8 go up in value?
3. Mazda RX-8. Mazda have recently announced that they will not be reintroducing the rotary power-train, most likely due to high running costs, unreliability and high emissions that come with the rotary way of life. … Equipped with a manual gearbox and rear wheel drive, the RX-8 is sure to increase in value.
Why do rotary engines use so much fuel?
The thing is; the rotary engines end up producing excessive power. The engines, in turn, are not built to handle the excessive power. As a matter of fact, the more power the more fuel is burnt as the revs of the vehicle get higher. This is the simplest reasons that explain why rotary engines offer a bad mileage.
How much does it cost to rebuild a 13b rotary?

How long do rotary engines last?
Those apex seals don’t tend to last long before they need replacing, either. Rebuilding a Wankel at 80,000-100,000 miles is typical, and earlier than most piston engine need such exhaustive work.
How often do you have to rebuild a rx8 engine?
You won’t need a rebuild until after 200000 as long as you keep oil full.
Should I premix my rx8?
For the high risk groups (1989-91 RX-7’s and the 2004-11 RX-8’s), 4oz of premix per 10 gallons of gas is exactly what we recommend. Their factory injection rate is so low that you almost notice no oil consumption whatsoever.
