Interesting. Ihave a mate who is at about the same stage in his build. The great thing about this swap is that the nc and the rx8 are essentially the same car/chassis, with a section cut out of the middle of the nc, and they even come off the same production line. This means that the whole engine and subframe, with the electric rack and 330mm odd rotors all bolts straight in without modification. A quick piccie for you.

I take it you were never taught when you were younger that if you had nothing inteligent to add to a conversation to keep your mouth shut?

I love this forum, so many people happy to offer their useless opinions and bash random things for no good reason

Actually, the Renesis is a damn fine engine. It just has virtually no margin for shitty tuning, and even less if with a turbo. Those who are well versed can get them to do amazing things, very reliably.

We have rotary motors at work that lived through entire race seasons, including through 24 hours races. How can a motor run wide open over multiple 24 hour sessions and not be reliable? Oh, and we race on PUMP gas.

We have our own on site rotary machine shop, run by a man who's got nearly 40 years' of experience building mazda rotaries. We could have dropped in a fancy motor, such as the 620hp 4 rotor that sits in front of my desk at work, but went with the Renesis for a reason.

And can you tell us why? It's amazing how people can make loud declaration and are not even able to bring arguments to support their declaration.

Rotaries are great motors, it's just the lack of knowledge, and horror stories that affraid people. And for the horror stories, it's well known that most of the time it's the lack of good maintenance that kills these engines. They sure needs mor TLC than piston motors, but they're lighter, smaller, less complicated, less parts moving, and run smoother. They sure consume oil but IMO it's not a big concern as somtimes big mileage piston engines consume more... I'm pretty sure that if mazda did not have bought the exclusivity of this motor, these motors would have a greater place on our roads and would not affraid people like this...

i used to have a 88, it was a peice of ****. nothing but a constant pain in the ***

this explains it perfectly


ford spent millions on that motor, if it was such a good motor, everything would have one. and they dont just "consume" oil, they are MADE to BURN ENGINE OIL.

and here is another little tidbit, mazda doesnt even include the RX8 in its customer satisfaction surveys, and there is a reason why. and lets not forget that the motor has been recalled already for low compression

How funny... because at that time, the contemporary RX7 won more IMSA races than any other car, GTU was dominated by the RX7, which won 24 hrs Daytona 10 years in a row (1982-1991) and won the championship 8 years in a row (1980-1987). It was done on RELIABILITY, not by power. Most of the contemporary piston motors put out HUNDREDS of horsepower more. HUNDREDS. This was because IMSA kept crippling the rotary by restricting it, because it was so dominating.

The RX8, especially the earliest ones, has had its share of issues. Most of them were electronic/programming in nature. The US spec RX8 got a really shitty tune. But the motor itself, when treated properly, is typically pretty robust.

The great thing about the Rotary in my limited experience is that it can be beat to **** and as long as heat is controlled life is good. The part I don't like about them is how random they are when they fail. Park it one day and it has compression, go to start it the next and nothing. Bye bye apex seal. Carbon build up bad.

Good race car motor, shitty daily driver motor in my opinion. And nothing sounds nearly as horrible as a rotary with a wide open exhaust. Weed whacker from hell.

Still think this is a cool swap, the MX-5 is such a boring safe car it needs something a little edgy to make it cool.

Never owned a DD rotary - only raced them, but it would seem to be true form most reports I've read that it requires more maintenance. I don't care much for the sound either EXCEPT for one - the last Mazda factory GTP car. That car was the best sounding rotary ever- probably because it sound more like a small bore, high rpm v8.
