The Mazda RX8 runs on a unique type of engine – rotary engine. It is an early specimen of the internal combustion engine that produces rotary motion to move the vehicle forward. Sometimes, you need to do a Mazda RX8 engine rebuildbecause some of its components are susceptible to damage. Let’s find out the causes that require the engine reconstruction and the RX8 engine rebuild cost.

Damaged Apex Seal
Blown apex seals are the most common reasons for the death of rotary engines. In fact, a crack in the seal is not the main culprit but the trigger that sets everything in motion and leads to the ultimate engine failure.
When you drive the car with a cracked apex seal, it shatters into numerous pieces. These fragments wreck everything on their way – the next two apex seals and rotor along with its housing. It leaves almost half of the engine in bad condition. You have to purchase the rotor and its housing to reassemble such an engine.
Cracked Coolant Seal
A leaked or faulty coolant seal will leak coolant into the combustion chamber and combustion gases into the cooling system. The seal can wear out with time, for a bad coolant jacket, or an overheated engine. In either case, the engine will need reconstruction.
Carbon Lock
Carbon can build up in the rotaries due to an irregular oil change or lack of engine redlining. Over time, the carbon layers can be so thick that they can prevent the engine from turning. The condition is very rare, though.

Here is a breakdown of the expenses to give you an idea of the budget required (the final costs will depend on the conditions of the engine).
$1,600 or less– When the rotor and its housing are in a good shape. Restoring within this meager budget will not equip the engine with full power. It will run for a few years, though.
$3,500 or more– You are looking at the figures if the engine needs new housings and other parts. It is the minimal estimation given that you purchase the parts at wholesale prices.
$4,000 to $6,000– A proper Mazda RX8 engine rebuildwill cost this amount of money. The service will include a fully-restored to power engine with a few upgrades for high power and longer lifespan.
If you are taking a professional service, be ready to pay $1,000 to $2,000 in labor and a few hundred dollars more in other stuff like fluid, gaskets, etc.
