How Long Do Rx8 Engines Last?

Can an rx8 be reliable?

The sound that its rotary engine makes when you hit the 9,000 rpm redline is intoxicating and the way the car carves through corners is sublime.

All this emotion comes at a hefty cost, though, as the Mazda RX-8 is one of the most unreliable cars you can buy..

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).

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.

How many miles can a rotary engine 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.

Why are rotary engines unreliable?

Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the exhaust. They also have problems with rotor sealing as a result of uneven temperatures in the combustion chamber since combustion only occurs in one portion of the engine.

Do rx8 have alot of problems?

Problem: 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.

Why do rx8 engines fail?

The problem is that there are so many different ways for an engine to fail: Excessive carbon buildup accelerates seal wear, causing compression loss (particularly a problem in automatic RX-8s) Excessive carbon buildup unseats the seals, causing compression loss (particularly a problem in automatic RX-8s)

How much does it cost to replace apex seals rx8?

well stock apex seals and springs cost couple hundred bux but to replace it, u have to take the engine out, open it, re-do all soft seals, clean and measure all parts then the builder has to decide what will be re-use and he rest goes to garbage. the whole process can range from 3k to 11k depends on what you want.

How do you maintain an rx8?

Here are a few of the common failure points on RX-8s, and how to prevent them.Failed apex seals. … Use dino (non-synthetic) oil only. … Allow the engine to reach redline at least a few times a week. … Allow the engine to warm up. … Perform a compression test with some regularity.More items…

Can you engine swap an rx8?

Before any RX-8 motor swap, it’s prudent to research before you begin. Of course, no motor transplants are going to be easy on the RX-8, and it can be argued that swapping out the RENESIS is sacrilegious.

How often should you replace apex seals?

The Apex Seals are an integral part of the combustion process, and therefore shouldn’t need to be replaced any more than you need an engine rebuild, for regular driving that is. Somewhere between 100-200k miles maybe less.
