ok the question is what are you willing to spend to get this thing to be a rocket... you get this thing chipped and moded you can make this thing take off.. im talking huge power and even more tourque..remember its a turbine, a freaking plane engine.. dio you think you want to race this?? start thinking bigger turbo.. straight exhaust.. nos... and reduce weight.. no cop would ever catch you!! think about what you want

Firstly to Darrin... Mazda=Ford nowadays Two, takek it to a track and find out for yourself. More fun than asking... Make sure your tires are speed rated though, and inflated properly. After all, it can only go as fast as you can make it go.

FYI, I work for the largest Mazda retailer in the Midwest and I like the RX-8. Originally Mazda wanted to make the RX-8 turbocharged but due to emission regulations in California it had to scratch that idea. A turbocharged RX-8 would not pass emission standards in California so Mazda went with the naturally aspired Renesis rotary. I hate California for this because if the RX-8 had a turbo it would sell a whole lot better. The car is amazing but it just can't compete in the horsepower category with the competition. You can top it off with the right mods to the car and go even faster.

I agree, a turbo RX-8 would have been an awesome car to follow up to the RX-7's standards. But today it's a failure to the Rotary Powered RX line because of no turbo. BTW, I drive a FC (2nd Generation RX-7), heavily modded, single turbo 13B, streetported, Racing Beat ECU, new exhaust, upgraded injectors, bigger turbine (14.8 PSI from factory 7 PSI). This can easily hit a top speed in excess of 260 km/h on long straightaways like the highway. An RX-8 will hit 150 tops. Only until a turbo is added.

I drive a turbo'd RX-8 as my daily driver. Beautiful car... flies to 100 (on the track, not on the streets) like it's nothing, and begs for more. I haven't found a track to test top speed, but from what I've read people with similar setups to mine can get to 170-ish. Attached a picture of the engine bay.

On Youtube. many of them can hit 160 without a Turbo.

Steve Hill

148 stock

Joseph Chambers

mayb km/h.....148 stock mph in 5th you can only get about 136 in 6th...ive poured money into mine like crazy and still havent found enough road to do 160 neways

The Wankel rotary engine is originally a German design, so it's not totally Japanese. American cars in the same price range are mostly crap anyways, but, to each his own.

Jos Clarke

top speed is reported at 146-148, however I have only been able to get it up to 140 (mine's standard). I bought it used so I'm not sure how well the previous owner treated it :(

Jacob Fraser

its a turbine.... sure cant be stock thiers only been one car ever made with a turbine engine....

Lukasz Szewczyk

How much power are you making on this best???????

Jake Schubel

For those that said its a turbine engine that is completely wrong. The engine is a 1.3 liter 2-rotor wankel. There is NO pistons, no cylinder head. If you really want to know more about it read up on


Apparently you are a moron and don't what you're talking about.

I have a 05 rx8 6 speed and when I kept my car stock I had no problem hitting 155mph in 5th gear Evey time and 165 in 6th. I haven't tried to go faster since I put a magnaflow exhaust and a Aem CAI

Paul Wilson

the real answer is "Faster than you will ever be able to go on most roads" lol. Fyi though before you try and hit the 180 mark in the car, upgrade the aerodynamics... otherwise the ending is not pleasant.

Jason LeBlanc

I've done 240km/hr in my 2004 RX8 6 GT. The auto's I'm assuming will have trouble hitting that with less power.

Calvin Howard

It doesn't matter the top speed of a car, a corvette can barely hit 100 mph in a 1/4 mile stock, I've seen that "jap" car eat a mustang gt for breakfast in a street race, say what you want but the rotary is a work of art and was band from insurance races because of its durability, you gotta hand it to the Japanese they know how to make more speed with less power better then anyone
